摘要：

The impact fatigue response of ultra-high molecular weight linear polyethylene (UHMW LPE), in a special test, has been examined and the results are presented in this paper. In an attempt to understand the influence of high molecular weight on impact strength, identical measurements were made on a normal molecular weight linear polyethylene (NMW LPE). UHMW LPE is found to have a superior impact and impact fatigue behaviour to the NMW LPE. Almost all of the UHMW LPE materials perform equally well in the present impact fatigue test. However, one of the high bulk density UHMW LPE materials, resin G, performs quite poorly. Photomicrographs of the free surface of this material show that this may result from poor interparticle fusion during compression moulding. © 1979 Chapman and Hall Ltd.
