Abstract

Blends of ductile Ti metal with polyetheretherketone (PEEK) polymer were studied with regard to their mechanical properties and in vitro biocompatibility. PEEK/Ti composites with various Ti contents, ranging from 0 vol % to 60 vol %, were produced by compression molding at 370°C. In all composites produced, regardless of the initial Ti content, Ti particles were well distributed in the PEEK matrix. Addition of Ti led to a significant increase in mechanical properties of PEEK. Specifically, an increase in Ti content enhanced compressive strength and stiffness, while preserving ductile fracture behavior. In addition, the use of Ti for reinforcement of PEEK provided the composites with improved in vitro biocompatibility in terms of the attachment, proliferation, and differentiation of MC3T3-E1 cells.
