The effect of volume fraction on the fatigue strength of unsaturated polyester-glass fiber composite

Abstract EN

In this work polymeric composites were done from unsaturated polyester as a matrix reinforced with glass fiber type (E-glass) with two different volume fraction 20 % & 40 %.

Fatigue tests showed that the number of fatigue cycles to failure limit for samples reinforced with uniform (woven Roving 0-90°) E-glass fiber and random (continuous fibers) with volume fraction 40 % more than that for the same samples with volume fraction 20 %.

Also the fatigue results showed that the uniform samples failed with fatigue cycles more than that of random.
