Yield stress of epoxy composites filled with quartz powder
The effect of the amount of quartz powder in an epoxy resin matrix was studied by compression testing. Compressive tests near room temperature and at several strain rates were performed on samples with different filler volume fractions. The data show that both the composite Young's modulus and...
