Synthesis and effect of epoxy in lamination for Kevlar / E-glass hybrid composites

A combination of their unique stiffness and strength, hybrid composites has great potential in a variety of industries, including medium-duty automotive, aircraft, and submarines. In order to evaluate the performance of kevlar/E-glass epoxy composites in this article concentrated on their fabrication and testing. It is well known that the composition has a major impact on the mechanical properties and functional traits of the composite. In order to ascertain the ideal epoxy mix, we thus used a manual layup technique to produce three unique composite sheets designated as P (2:3), Q (2:4), and R (3:2). Research follow ASTM guidelines while analyzing the mechanical parameters, concentrating on tensile strength and binding strength to assess overall structural integrity. As a way to find the interlayer laminar strength between Kevlar fibre and epoxy provide information on interfacial properties, delamination experiments were also carried out. Comparing composite sample P (2:3) to other compositions, our results showed that it had the lowest swelling ratio and the best mechanical qualities. Composite sample Q (2:4), on the other hand, showed the best interlaminar characteristics and adhesion capabilities. The significance of composition mix in attaining targeted performance attributes in hybrid composites is highlighted by these findings.
