Abstract

The effect of mechanical and physical properties of polymer matrices on STRESS AMPLIFICATION FACTORs is studied in a composite monolayer. The LAMINA is subjected to an elliptical damaged zone of radii "a" and "b" while loaded at infinity by a force "P". The matrix takes both axial and shear loads. The ratio of a/b is allowed to vary in a range of 0 < a/b , to simulate almost a crack and a circular hole, for the two values of a 0 and a = b, respectively. Any reduction in STRESS AMPLIFICATION FACTOR Kr, and peak shear stress in the matrix (Sxy)max, appears to well depend on the value of matrix to fibre volume fraction Vm/Vf, and their mechanical properties, as well as shape and size of the hole. For polypropylene and epoxy matrices, at a/b = 0.5 and r = 5, increasing Vm/Vf from 0.5 to 2.0 decreases (Sxy)max by 62% and 73%, respectively, while Kr is decreased by 17%.
