The effect of fiber orientation on creep behavior and flextural strength in epoxy composites

الملخص EN

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 (90˚-0˚) 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) ˚C.

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.
