"High performance radiolucent composite materials for use in medicine, providing suitable mechanical properties and high resistance against sterilization decomposition, will be prepared. The composites will be composed of carbon, aramide or glass fabrics embedded in polydimethylsiloxane or polyphenylene sulfide matrix. The desired mechanical properties and dimensional stability will be optimized by adjusting the structure of the composites. The fatigue properties, stiffness and strength characteristics, and abrasion resistance will be determined. The effect of multiple sterilization processes on the degradation of mechanical properties, dimensional stability, structural integrity and hydrolytic decomposition will be verified, as well as the radiolucency of the composites and their constituents. The ability to be formed by widely-used manufacturing processes and the influence of these processes on the mechanical behavior of the composites, namely fatigue properties and structural integrity, will be tested. A study will be made of the effect of the composite materials, as well as their individual components, on cytotoxicity (in vitro tests)."@en . . . "34"^^ . "34"^^ . . .
