摘要：
The present disclosure provides a polymer-ceramic based hybrid composite material for producing a biocompatible and highly wear resistant acetabular cup, wherein the composite material can include 60 to 80 % by weight of high density polyethylene, 10 to 30 % by weight of hydroxyapatite, 10 to 30 % by weight of alumina and 0.5 to 5 % by weight of titanate coupling agent. The present disclosure further provides a process for producing a composite material, wherein the process can include a number of sequential steps, (a) forming a first mixture comprising a coupling agent and a solvent (b) admixing the first mixture and one or more ceramic fillers to obtain a second mixture (c) wet milling the second mixture to obtain a slurry containing modified ceramic filler particles (d) drying the slurry obtained from (c) to obtain dried filler particles and (f) dry milling the filler particles obtained from (d) with a high density polyethylene polymer to obtain the composite material. Furthermore, the present disclosure provides a method to design and develop patient-specific acetabular sockets from the polymer-ceramic based hybrid composite material with wear resistance and biocompatibility properties.
