摘要：

A new material consisting of high-modulus polyethylene fibres in a polyethylene matrix (PE/PE) has been prepared and its properties evaluated. After first discussing what matrix characteristics are required to get a good composite with fibre volume fraction about 0.7, this paper describes the manufacturing method from prepreg preparation up to the moulding process including post-treatment by electron irradiation. Mechanical properties of the unidirectional PE/PE laminates are then presented. In the fibre direction, strength and modulus values are intermediate between those of carbon/epoxy and aramid/epoxy composites whereas the usual weakness is observed for off-axis properties. Material irradiation has a negligible effect on both fracture and time-dependent properties. Physical aspects like crystallinity and electromagnetic properties of PE/PE are also discussed.
