COMPOSITES INCLUDING SILICON-OXY-CARBIDE LAYERS AND METHODS OF MAKING THE SAME

摘要

Composites comprising at least one silicon-oxy-carbide (SOC) layer deposited onto a polymeric matrix substrate to enhance their thermo-oxidative stability are provided. The SOC layer is formed onto the polymeric matrix substrate by atmospheric plasma deposition to produce an thermo-oxidative barrier coating or an adhesion-promoting layer to enable the deposition of a variety of known (or future developed) metallic and/or ceramic materials as oxygen and/or thermal barriers.
