摘要：

Tensile and creep tests have been conducted on monofilaments of gel-spun high-modulus polyethylene fibres. Fibre strength has been determined over a temperature range - 175-100-degrees-C. The creep studies have revealed changes in behaviour which depend on the applied stress and the temperature. The results of these studies are explained by a change in crystallographic structure from orthorhombic to hexagonal which can take place under certain conditions of temperature and applied stress. It has therefore been possible to determine the applied stress necessary to obtain the change of phase as a function of temperature.
