Multiscale characterization of the textile preform made of natural fibers is an indispensable way to understand and assess the mechanical properties and behavior of composite. In this study, a multiscale experimental characterization is performed on three-dimensional (3D) warp interlock woven fabrics made of flax fiber on the fiber (micro), roving (meso), and fabric (macro) scales. The mechanical tensile properties of the flax fiber were determined by using the impregnated fiber bundle test. The effect of the twist was considered in the back-calculation of the fiber stiffness to reveal the calculation limits of the rule of mixture. Tensile tests on dry rovings were carried out while considering different twist levels to determine the optimal amount of twist required to weave the flax roving into a 3D warp interlock. Finally, at fabric-scale, six different 3D warp interlock architectures were woven to understand the role of the architecture of binding rovings on the mechanical properties of the dry 3D fabric. The results reveal the importance of considering the properties of the fiber and roving at these scales to determine the more adequate raw material for weaving. Further, the characterization of the 3D woven structures shows the preponderant role of the binding roving on their structural and mechanical properties.

The feasibility to manufacture a 3D warp interlock preform from 1000 Tex flax roving is investigated by means of a prototype machine developed to GEMTEX laboratory. The provided flax roving has low tensile failure load because of lack of twist so it isn’t suitable for weaving. The first step was dedicated to improve the tensile properties of the roving through twisting process and identifies the optimal twist level. Experimental campaign is conducted by applying different twist level and evaluates the roving tensile properties. The ultimate tensile load increases as roving twist level increases until a threshold at which the tensile load declines as twist level increases. While the failure strain increases continuously as twist level increases. Five fabrics are produced with the same flax roving, 3D weave architecture and warp number and weft column number per unit length. Only the number of weft layers varies. The physical and tensile properties of these five flax fabrics are characterized experimentally. A considerable effect on the thickness and areal density of the fabric is reported. The difference in the waviness length between the two types of the warp roving (reinforcing and binding) has a significant impact on the tensile behavior of the fabrics in warp direction through the appearance of two phases on the force-strain curve. Otherwise, the variation of the number of layers does not induce a remarkable impact of the fabric structure on the tensile performance of the constituting roving.

The present study carries on the characterization of dry reinforcement structure for composite material. Yarn properties were analyzed to select the optimal level of twist. The influence of 3D-warp interlock structure's bending type was also investigated. Structures, made with 1000Tex flax roving, were woven on a dobby loom. Physical characterization and mechanical testing (tensile test) were conducted on the four different binding structures (AL, AT, OL and OT) to provide relevant data and identify the influence of the binding warp yarns' path inside 3D warp interlock structure.

An increase in the use of composite materials, owing to improved design and fabrication processes, has led to cost reductions in many industries. Resistance to corrosion, high specific strength, and stiffness are just a few of their many attractive properties. However, damage tolerance remains a major concern in the implementation of composites and uncertainty regarding component lifetimes can lead to over-design and under-use of such materials. A combination of non-destructive evaluation (NDE) and structural health monitoring (SHM) have shown promise in improving confidence by enabling data collection in-situ and in real time. In this work, infrared thermography (IRT) is employed for NDE of tubular composite specimens before and after impact. Four samples are impacted with energies of 5 J, 7.5 J, and 10 J by an un-instrumented falling weight set-up. Acoustic emissions (AE) are monitored using bonded piezoelectric sensors during one of the four impact tests. IRT data is used to generate diffusivity and thermal depth mappings of each sample using the thermographic signal reconstruction (TSR) red green blue (RGB) projection technique. Analysis of AE data alone for a 10 J impact suggest significant damage to the fibres and matrix; this is in good agreement with the generated thermal depth mappings for each sample, which indicate damage through multiple fibre layers. IRT and AE data are correlated and validated by optical micrographs taken along the cross section of damage.
