In this work, an attempt was made to improve the mechanical performance of glass fibre-reinforced polymer composites by adding multi-walled carbon nanotubes (MWCNT) and graphene nanoparticles (GNP) and their hybrid combination at different weight fractions (0.1 to 0.3%). Composite laminates with three different configurations (unidirectional [0°]₁₂, cross-ply [0°/90°]_3s, and angle-ply [±45°]_3s) were manufactured using the compression moulding method. Characterisation tests such as quasistatic compression, flexural, and interlaminar shear strength properties were carried out per ASTM standards. Failure analysis was carried out through optical and scanning electron microscopy (SEM). The experimental results showed a substantial enhancement with the 0.2% hybrid combination of MWCNTs, and GNPs showed 80% and 74% in the compressive strength and compressive modulus, respectively. Similarly, flexural strength, modulus, and interlaminar shear strength (ILSS) increased by 62%, 205%, and 298%, respectively, compared to neat glass/epoxy resin composite. Beyond the 0.2% of fillers, the properties started to degrade due to the agglomeration of MWCNTs/GNPs. The order of layups per mechanical performance was UD, followed by CP and AP.

Lithium-ion batteries are the main bases available for electric vehicles and hybrid electric vehicles, because of clean energy transportation as compared to other power sources developed by traditional I.C Engines. In order to get high discharging Lithium-ion batteries battery condition, there is a significant temperature difference should be maintained in between battery temperature and appropriate local temperature. In this paper presents the model designed with different type of heat pipe shapes modeling in CREO parametric software and analyzes the heat pipe with different mass flow inlets (30& 50L/min) thermal thermal analysis done in ANSYS to determine the temperature distribution and heat flux for two types of phase change materials (RT50 & Li Fe PO₄). Also, Computational Fluid Dynamics analysis (CFD) is to calculate pressure (pa), velocity (m/s), heat transfer coefficient (w/m²k), mass flow rate (kg/sec) and heat transfer rate (w) for the different designs of heat pipe and different mass flow inlets. It has been observed that in thermal analysis the heat flux value is more for lithium ion phosphate phase change material (Li Fe PO₄) than RT50 phase change material at U-bend heat pipes. Similarly in CFD analysis observed that mass flow rate (kg/sec), heat transfer rate (w), heat transfer coefficient (w/m²k) values are increases by increasing the mass flow inlets and heat transfer rate more at straight type heat pipes as compared to bend type.
