Effect of boron carbide particle addition on the thermomechanical behavior of carbon matrix silicon carbide particle composites

摘要

Carbon-matrix composites are important for lightweight high-temperature structures.However,carbon suffers from the tendency to be oxidized. Due to its superior oxidation resistance,silicon carbide is used in combination with carbon,whether it is a part of the matrix or a part of the oxidation of carbon through the gettering of oxygen,boron carbide and other boron compounds are also used in combination with carbon [3-5].
