STUDY THE EFFECT OF POLYPROPYLENE FIBERS IN SOME MECHANICAL AND PHYSICAL PROPERTIES OF RIGID POLYURETHANE FOAM COMPOSITES
A foam composite material was set by adding polypropylene fibers diameter of 18 μm and 6 and 12 mm length to rigid polyurethane foam with a weight fraction of (2.5-15 )%wt. The results had shown improvement on (flexural strength, compressive strength, hardness, impact strength) and increase in flex...
