Effect of the Matrix and Filler Phase Composition on the Erosion Resistance of Carbon-Carbon Composite Materials Fabricated by the Gas-Phase Infiltration Method

Abstract

The erosion factor of the matrix and filler phase composition having influence on the C-C composite resistance has been shown. The main mechanisms of such an effect are determined and the steps of improving the functional characteristics of composites are determined. It is assumed that the erosion and sublimation resistance of C-C composites, obtained by the gas-phase infiltration method using the radially-moving zone of pyrolysis, is due, first of all, to a highly-ordered crystalline pyrocarbon matrix. It is shown that the C-C composites have a unique temperature resistance and workability at high temperatures.
