Abstract

As material requirements become more and more sophisticated, there seems to be a substantially greater emphasis on the development of advanced thermostructural composites such as C/C, C/SiC and SiC/SiC, because of their high-temperature strength, thermal shock resistance, low thermal expansion coefficient, good heat conductivity, hardness, abrasion resistance and low density. The excellent mechanical and thermophysical properties of such thermostructural composites provide many potential applications for these materials, including re-entry shields, rocket nozzles, disc brakes and prosthetic devices. Nevertheless, these materials also have their weaknesses, C/C composites are tough and elastic, but have poor oxidation and abrasion resistance and poor thermal conductivity. On the other hand, C/SiC and SiC/SiC have good oxidation and abrasion resistance and good thermal conductivity but are brittle and rigid. The aim of the proposed applicative research is to develop a material that will unite the good properties of above-mentioned composites and avoid their weaknesses. Various possibilities for the production of C/C-SiC composites with a gradient structure of ceramic matrix, from carbon matrix in the core to SiC matrix on the surface, will be investigated. The use of various new ceramic-forming polymers for the preparation of the matrix will be researched and the interactions between constituents of the composite will be studied.
