STUDY OF FATIGUE PROPERTIES FOR EPOXY / GLASS FIBER COMPOSITES

Abstract

This work is aimed to prepare polymer matrix composite material by Hand lay – up molding from Epoxy resin reinforced by woven Roving (W.R) or random glass fiber type (E-glass ) at different layers and volume fraction 25%. The experimental results show that the number of fatigue cycles to failure decrease with increasing the number of reinforcing layers for all samples in the dry and wet cases . Also the results show that the number of fatigue cycles for immersed samples in water less than that of the same dry samples.
