Effect of heat treatment on the flexural properties of a titanium matrix compositeTitanium matrix composites (TMC) reinforced with carbon fibers are widely used in the aerospace industry due to their light weight, high strength and modulus and the retention of their strength and modulus at elevated temperatures. Liquid infiltration, a low cost technique for making TMCs, has been little used due to the extent of the reaction between titanium and carbon during fabrication. Rapid infrared processing (RIP) has been developed as a technique for reducing interfacial reaction during composite fabrication. The strength and modulus of composites produced using RIP were higher than or comparable to those for other composites. This paper examines the effect of heat treatment on the room temperature flexural strength and modulus of TMC produced using RIP. The experiments carried out are described and results are presented. Results showed increased flexural strength of the composites upon aging at temperatures of 800 and 900 degrees C. This increased strength may be due to increased strength of the matrix.
