This paper assesses the aspects related to sustainability of polymer composites, focusing on the two main components of a composite, the matrix and the reinforcement/filler. Most studies analyzed deals with the assessment of the composite performance, but not much attention has been paid to the life cycle assessment (LCA), biodegradation or recyclability of these materials, even in those papers containing the terms “sustainable” (or its derivate words), “green” or “eco”. Many papers claim about the sustainable or renewable character of natural fiber composites, although, again, analysis about recyclability, biodegradation or carbon footprint determination of these materials have not been studied in detail. More studies focusing on the assessment of these composites are needed in order to clarify their potential environmental benefits when compared to other types of composites, which include compounds not obtained from biological resources. LCA methodology has only been applied to some case studies, finding enhanced environmental behavior for natural fiber composites when compared to synthetic ones, also showing the potential benefits of using recycled carbon or glass fibers. Biodegradable composites are considered of lesser interest to recyclable ones, as they allow for a higher profitability of the resources. Finally, it is interesting to highlight the enormous potential of waste as raw material for composite production, both for the matrix and the filler/reinforcement; these have two main benefits: no resources are used for their growth (in the case of biological materials), and fewer residues need to be disposed.

This paper compares the mechanical properties of different natural fiber composites produced by rotational molding as a way of waste valorization from campaigns to control invasive plant species in Macaronesia. Rotomolded parts produced with polymeric matrices (polyethylene) and filled with up to 20% by weight of cellulosic fibers obtained from Arundo donax L., Pennisetum setaceum, and Ricinus communis plants were characterized in terms of tensile, flexural, and impact strength. It was found that the sieving of natural fibers allowed for their introduction in higher loadings, from 10 (for un-sieved material) to 20%; fiber size greatly affected the mechanical properties of the final parts, although some combinations were proven not to reduce the mechanical properties of the neat resin. This study is a first approach to the valorization of residues obtained from periodic campaigns of the control of invasive species performed by public authorities, usually at the local level. It is important to highlight that the main objective of this research did not focus on economically profitable activity; instead, it was focused on the reduction of wastes to be disposed from ecosystem maintenance actions and the investment of potential income into preservation policies.

This paper summarises the results obtained from the characterisation of giant reed (Arundo donax L.) plant and fibres. The research is part of a project developed in the Macaronesia region, of which the aim is to demonstrate the feasibility of using biomass from invasive plant species in the composites sector as a way of financing control campaigns and habitats conservation labours. An experimental procedure for the extraction of fibre bundles from this plant was developed, and the material obtained was characterised in terms of chemical composition, thermogravimetry and infrared spectra to evaluate its potential application in the production of polymeric composite materials as a strategy for the valorisation of residual biomass from this invasive species in Macaronesia. Thermoplastic matrix composites with fibre content up to 40 wt.% were produced and their mechanical properties under tensile, flexural and impact loading were determined. No references on the preparation of composite materials with polyolefin matrices and giant reed fibres have been found. Results obtained from mechanical tests show a good performance of the manufactured composites, with a significant increase in both flexural and tensile stiffness; the flexural modulus is almost tripled for PE-based composites and rises to 88% with respect to PP matrix. The ultimate flexural strength and the tensile and flexural yield strength are kept at acceptable values compared to neat polymer materials, although ultimate tensile strength and impact resistance are significantly affected when natural fibres are added.

A fire extinguisher is a portable element designed to fight emerging fires, with a useful life of around 20 years. After this period, they are withdrawn from the market. All their components (shell, hose, and so on) are usually separated and recycled, except the chemical powder used as extinguishing agent, which usually consists at monoammonium phosphate (MAP), widely used in the production of agricultural fertilizers. Although there are several companies dedicated to this task, in the case of remote areas or islands such as the Canary Islands, there are no options to recycle this component and the shipping is unaffordable. As a result, the companies of this sector (distributors of fire‐fighting systems) tend to accumulate them in large quantities. In order to give a second use to this dry chemical powder, this work analyzes its potential as an additive for a polyethylene matrix. This would not only take advantage of a currently unused raw material but would also improve the fire resistance performance of polyolefins thanks to the fireproof properties of the extinguishing agent. Samples with different proportions of dry chemical powder were elaborated and tested to determine their mechanical and fire properties, achieving composites with significant improved fire performance regarding the net matrix.

This paper consists in a review of environmental issues of additive manufacturing technologies, mainly in those related to fused deposition modelling. The versatility, reduction of equipment costs due to patents expiring and the great flexibility offered by 3D printers have driven the amazing increase of these technologies in the last years. On the other hand, the democratization of additive manufacturing also poses some issues regarding environment; it is important to also have into account the potential effects of these technologies in the environment, coming from energy consumption, materials, and wastes produced. A review of different research works dealing with environmental impact of additive manufacturing, such as products’ life cycle assessment, energy and materials consumption, and particles and gases releases (mainly due to health issues), has been performed. The assessment performed has helped highlighting the importance of environmental issues in additive manufacturing, according to the number of published papers. The main findings are the importance of establishing a method for applying eco-design principles taking into account the specific features of additive manufacturing.

This paper summarises the results obtained from the characterization assays from century plant (Agave americana L.), determining the chemical composition of different parts of the plant. Fibres were obtained by means of a mechanical device, specifically designed and built for Agave americana leaves processing. Obtained fibres were subjected to thermogravimetric analysis and infrared spectra, and their chemical composition was also determined by quantitative acid hydrolysis. Once obtained, fibres were blended up to 40% (in weight) to obtain composites by compression moulding, using polyethylene as matrix; mechanical testing show improvements in elastic modulus for both tensile and flexural tests; increase in flexural maximum strength were also found for the composites, while tensile strength is slightly reduced with the introduction of agave fibres. The research is part of a project developed in the Macaronesian region, which aim is to demonstrate the feasibility of using biomass from invasive plant species in the composites sector as a way of financing control campaigns and habitats conservation labours, which is the main novelty of this research.

The use of natural fibres allows reducing environmental impact, due to their natural renewable origin and the lower energy needed for their production and processing. This work presents the mechanical characterization of a newly developed technical textile, with banana fibre treated by enzymes, comparing experimental results with numerical simulation based on the definition of the unit cell at micromechanical level. The experimental test shows that the composite with the fabric of banana fibre presents worse mechanical behaviour than the one with commercial flax fibre. The presence of wool, necessary for producing the yarn, reduces the mechanical properties of the banana textile. The numerical simulation had an acceptable error compared with the experimental results, with a global average error of 9%, showing that the predictive modelling based on the multiscale method is suitable for the design process of this kind of composite.

Research about selection has been focused to the material and current process selection methodologies/tools have problems. Consequently, a methodology for preliminary process selection was created through its integration in a design process. It allows manufacturing influence in early design stages through creating organizational knowledge. This storage of learning, integration and minimum viable product are key aspects. This paper addresses its application in industrial and university environments: manufacturing companies, design professionals, subject and final degree project. The obtained results show that methodology is validated and that the use of existing Manufacturing Process Selection methodologies is not enough for a correct selection.

The purpose of this chapter is to describe experience in the development, use, and evaluation of interactive didactic material oriented towards the ISO GPS system that has been introduced into recent academic courses of subjects of various engineering degrees at the University of Las Palmas de Gran Canaria. The Educational Innovation Group Ingeniería de Fabricación sought to generate a tool that would help students with a learning difficulty that had been identified as generalizable across various degree subjects. Student feedback was utilized in the development and evaluation of this didactic material. The results obtained allow us to confirm that the introduction of these materials has had a positive impact and that this preliminary experience of adaptive learning should be supplemented further in order to extend the significant improvement observed, both in the students' learning and the lecturers' teaching, in the last academic year.

Currently, methodologies of manufacturing processes selection are not clearly oriented for the early phases of the design process. Industry 4.0 has offered new opportunities to improve the integration of design and manufacturing processes. As a result, a methodology based on Design for Manufacturing and Assembly and organisational knowledge was created through its integration into an existing design process: Gero’s function-behaviour-structure variables framework. This methodology, called Manufacturing Process Selection Integrated in the Design Process, has been included in Interactive Didactic Material, and its application is expected to contribute to the use of these kinds of tools which will be instrumental in training future Engineers.

Banana fibers have been extracted by mechanical means from banana tree pseudostems, as a strategy to reevaluate banana crops residues. Extracted long fibers are cut to 45 mm length and then immersed into an enzymatic bath for their refining. Conditions of enzymatic treatment have been optimized to produce a textile grade of banana fibers, which have then been characterized. This fiber has then been transformed into yarns and woven to produce a technical textile with different textile structures. Woven material was then used to produce a composite by compression molding, using polypropylene (PP) as polymeric matrix. Once the composite was prepared, mechanical testing was carried out (tensile, flexural and impact tests). Results were compared to those obtained with parts made only of PP and with results composite made with a commercial woven product made of flax.

The fourth dimension in 4D printing refers to the ability of materials to alter its form after they are produced, thereby providing additional functional capabilities and performance-driven applications. Stimuli materials provide this capability through the use of shape memory polymers. For this research, the property of programming the determined shape is achieved through controlled heat under laboratory conditions. This paper shows the potential to process and experiment with thermoplastic polyurethane as a shape memory material. Taking a step further, we ascertain the properties of this material through extrusion-based additive manufacturing processes and produce parts for testing. The results show that the characteristics of the 3D printed parts successfully retain the property of the shape memory and the recovery force allows this to be utilised as a mechanical actuator. The recovery stress has been recorded to be between 0.45 and 0.61 MPa (at feed rate 990 mm/min). The maximum level of recovery stress is similar to the same material being processed through conventional compression moulding. Lastly, we designed and produced a coil as an actuator to demonstrate that the same material can be extended to other applications.

This work is part of a methodological renovation project from Ingeniería de Fabricación Innovative Education Group, from University of Las Palmas de Gran Canaria. It has developed learning materials for courses in Manufacturing Engineering that can be used in several degrees. In this first learning material, it was decided to take a plastic injection mould as a teaching resource, and can be summarized into design and manufacture a plastic injection product whilst developing a teaching material aimed to explain the necessary stages to make an injection mould, as well as the manufacturing processes related to it. All this work has generated a lot of educational material for both laboratory practices and multimedia. Abundant information generated has been used to develop an interactive electronic publication. Finally this learning material has been chosen by the Publishing and Scientific Diffusion Service from this University, as a new line of work in publications of educational innovation.

The small wind energy produces electric energy using power turbines below 100 kW. This technology allows the electrical supply in places isolated, generates energy of way distributed (distributed microgeneration) and permits to produce electricity in the points of consumption. The rotomoulding process is characterized to allow hollow plastics parts, with great surface quality, good homogeneity of thicknesses and suitable mechanical properties, all this with a great freedom of design and a wide variety of materials. The Department of Economy and Competitiveness from Government of Spain, inside the Subprogram INNPACTO 2012, resolved to grant the project of title Development of new blades made for rotational moulding for small wind generators (RotEos). The main purpose of this project is focused on getting a viable and cheaper process to manufacture the blades to small wind generators without reducing the efficiency of them, and trying to increase the competitiveness of these turbines. This research work presents the initial results obtained in the design of the blades, materials characterization and in the manufacturing process of these components.
