Design and Experimental Investigation on Tensile Strength Properties Using Different Forms of Layers for Epoxy Materials

Abstract

In aeronautical, marine and automobile industries the use of composites has increased due to their high stiffness and strength-to-weight ratios long fatigue life, resistance to electrochemical corrosion and other superior material properties of composites. In this paper, the experiments of vibrational analysis are carried out using Kevlar. Samples of Kevlar composites of different layers are used in this research. composites are truly materials of future, composites will help in developing components with better fatigue life and strength also these composite components can be tailor made to match the exact requirement. In this work we are developing and studying the behaviours of two different composites (regular and hybrid), hybrid composites are those which have multiple fiber reinforced lamina in their laminate.

Configurations of the composites are as follows 

E-glass/epoxy(0)_3, E-glass/epoxy(0)₅, E-glass-Kevlar/epoxy(0)₃,E-glass-Kevlar/epoxy(0)_5, E-glass/epoxy(0)₃(2mm – 2^nd layer thickness)_, E-glass/epoxy(0)₅(2mm – 2^nd & 4^th layer thickness), E-glass-Kevlar/epoxy(0)₃(2mm – 2^nd layer thickness),E-glass-Kevlar/epoxy(0)₅(2mm – 2^nd & 4^th layer thickness) in hybrid composite specimens reinforcement is changed in alternative layers.
