This article deals with very specific wear resistance testing of the biomaterials used for surgical implants. The abrasion is indispensable parameter for evaluation of the mechanical properties of these materials. This type of testing is very important for appreciation of new direction in total knee replacement, based on a new combination of biomaterials. The special wear resistance test is called "RING ON DISC". The experiments were carried out on the system MTS 858 MINI BIONIX placed in "Laboratory of Biomechanics of Man" at the Czech Technical University in Prague.

Carbon-carbon composite plates with three different reinforcement styles were manufactured and tested for mechanical properties and biocompatibility in view of their application as implants in bone surgery. Their stress state under load on bending was simulated by the Finite Element Method. The shape of the plates was designed to match the pig femur. The reinforcement was made of plain-weave carbon fabric lamina by stacking, coiling, or combination of both. Phenolic resin was used both as a precursor of the rnatrix and an impregnant. After final heat treatment at 2200°C a layer of pyrolytic carbon was deposited to reduce the formation of carbon particles. The plates with combined reinforcement yielded higher bending strength and lower stiffness on bending than those of human bones. Biocompatibility of the material was tested using "in vitro" and "in vivo" tests. The FEM stress distribution simulation yielded a good agreement of the failure location and bending strength value with the experimental data.
