Study the effect of polypropylene fibers in some mechanical and physical properties of rigid polyurethane foam composites

Abstract EN

: 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 flexural modulus, density and water absorption, with decreases in thermal conductivity of the resultant foam composite as compared with neat rigid polyurethane foam
