Abstract

In this study, the solid-state extruded high-density polyethylene with various extrusion ratios was prepared and the effect of molecular chain orientation on the fatigue behavior of HDPE extrudate was investigated. It is found that the fatigue fracture behavior of the extrudates is different from that of the unextrudate. The direction of cyclic deformation is same as that of the extruding direction. The fatigue fracture surface of the unextrudate was normal to the direction of the cyclic straining. The fatigue fracture surface of the extrudates exhibited characteristic feature depending on the mode of cyclic straining. In the case of the tension-compression type fatigue tests, the fracture surface inclined to the direction of cyclic deformation by 45 degrees.
