Mechanical Properties ofi-PP/AI Composites

Abstract
Mechanical properties such as tensile, flexural, and impact behavior of Al powder-filled polypropylene composites were studied in the composite composition range 0–10 vol% Al. Tensile strength, modulus, and breaking elongation decreased with increase in filler content due to the formation of weak structure. Analysis of tensile strength data demonstrated the introduction of stress concentration into the structure. Flexural strength and modulus increased with filler content due to increase in rigidity. Izod impact strength at first increased up to a critical Al concentration, beyond which the value decreased.
