Abstract

Short mineral fiber reinforced polypropylene composites have been investigated in order to determine their static properties. Tests have been performed on composites with different fibers (basalt and ceramic) and with different reinforcing contents (5, 15, and 25 wt%). The composites were made of fibers consolidated by a carding technique combined with needle-punching. Composite properties such as tensile and flexural strength, stiffness and fracture toughness have been calculated. It has been realized that mechanical properties strongly depend on fiber content and the direction of fibers. These results have been supported by scanning electron microscopy taken from the fracture surfaces and by the acoustic emission method.
