Study of the Effect of Reinforced Glass Fibers on Fatigue Properties for Composite Materials

Abstract

This research included the study of the effect of reinforced glass fibers on fatigue properties for composite materials. Polyester resin is used as connective material(matrix) in two types of glass fibers for reinforced. The first type is regular glass fibers (woven roving) with the directional(0-90), the second is glass fibers with the random direction. The first type is the panels with regular reinforced (0-90), and with number of layer (1,2). The second type is the panels with random reinforced and with number of layers (1,2). The results and the laboratory examinations for the samples reinforce with fibers have manifested (0-90) that there is a decrease in the number of cycles to the fatigue limit when the number of reinforce layers have increased . And an elasticity of this type of samples are decreased by increasing the number of reinforced layers with fiber .We find the random reinforced number of fatigue cycles for the samples with two layers of random reinforced are decreased more than the samples with one layer of random reinforced .
