Abstract

The creep behavior, flexural strength, shear stress was investigated in this
paper for epoxy, epoxy composite reinforced with glass fibers: (chopped strand mat),
woven roven (90о-0о) and chopped strand mat together as a sandwich composite with
volume fraction (21, 25, 29) % for each type. The tests were done at constant
temperature (room temperature (23 ± 2) оC.
The results shown that the increasing in volume fraction increases the creep
behavior, flextural strength, shear stress for all samples also the results shown the
effect of fiber orientation in increasing the creep behavior, flextural strength, shear
stress in sandwich composites in comparession with the composites reinforced with
randomly glass fibers.
