Experimental evaluation demonstrates reduced wear rate and elevated tensile strength in reinforced PEEK composites, highlighting their utility for artificial hip joints.
Key Points
Graphene oxide and hydroxyapatite reinforcement increases the tensile strength of polyether ether ketone, and the composite exhibits substantially lower wear rates.
Tensile strength reaches 65.10 ± 1.12 MPa with dual nanofillers—a 2.2-fold increase over bare polymer—while wear rate decreases by more than half under friction testing.
Assessment using compression molding and reciprocating wear testing demonstrates reduced coefficient of friction, highlighting viability for artificial hip repair applications.
