Experimental and numerical analysis of tensile and flexure tests on a hybrid Aramid/E glass composites

This paper focuses on the characterization of Hybrid Fiber Reinforced Polymer (HFRP) specimens made through a hand lay-up process, consisting of unidirectional Glass Fiber Reinforced Polymer (GFRP) and aramid Fiber Reinforced Polymer (AFRP) plies stacked in the same direction with an orientation angle of 0 degrees and varying thicknesses. Tensile and flexure tests were conducted following ASTM standards, and the results were examined. Additionally, Finite Element Method (FEM) using ABAQUS software was employed to study the properties of these hybrid composites. A comparison between experimental and FEM results was made. The HF4 composite, with a high thickness, exhibited superior tensile strength and modulus of elasticity of 302 MPa and 14.26 GPa, respectively. The flexure test of the HF4 hybrid composite laminate demonstrated a flexible structure with a bending modulus of 9.96 GPa. The findings suggest that the inclusion of aramid fiber and glass plies as an extreme can significantly improve the characteristics of hybrid composites.
