Abstract
Recent research on the mechanical properties of hot-compacted polypropylene composites is reported. It is shown that incorporation of new high performance polypropylene tapes leads to significant improvements in tensile and flexural properties. The high temperature properties of these new composites are outstanding, showing higher stiffness and very low creep under permanent load. Comparisons are presented with both chopped glass-reinforced and continuous glass-reinforced polypropylene composites. [ABSTRACT FROM AUTHOR]
