Abstract

Abstract The effect of mid layer on flexural strength and young modulus were studied using Instron testing machine. E-glass/epoxy composites were manufactured using hand lay-up technique. The laminated composites were prepared with dimension (4x10x80) mm, Epoxy composites were reinforced with multidirectional layer of woven glass fiber and random glass fiber of stacking sequence [M]16, [R]16, [M/R//M1/M1//R/M]s, [//M/R//]s, and [R/M//R1/R1//M/R]s. The effect of transverse loading on flexural strength and young modulus was investigated for specimens subjected to Three-point bending test. The results show that the mid layer (M1/M1) which had (homogeneous distribution) has higher flexural strength value and young modulus than mid layer (M1/R1) and (R1/R1).
