Effects of Milling Time and HA Contents on Microstructure and Mechanical Properties of HAlUHMWPE Composite
HNUHMWPE powder was mixed by ball milling. and then hot pressed into composite. The microstructure and the mechanical properties of the composite were characterized by XRD. SEM and mechanical tests. The results showed that the HA did not decompose. There was not new chemical substance produced. The tensile strength decreased with increasing HA contents. But impact strength increased then decreased. and reach to the maximum value when the HA content was 20vol％. The tensile and the impact strength of the composite showed an ascending trend with the increase of ball milling time. There are good combination of mechanical properties and fracture when milled 40h.
