Abstract

Fiber-reinforced, heat resistant ceramic composites are made from a fiber material and a ceramic matrix. The ceramic matrix includes nanoparticles to improve heat resistance and strength of the composite material. The nanoparticles in the matrix composition disperse more evenly through the fiber material and penetrate into small pores on the surface of the fibers. Once cured, the dispersed nanoparticles improve bonding between the ceramic matrix and the fiber, thereby improving the overall strength of the composite material. In addition, the ceramic nanoparticles improve the density of the ceramic matrix and render the composite material exceptionally heat resistant. The strength and heat resistance of the ceramic composites of the present invention are particularly advantageous when used to make exhaust pipes for helicopters. The light weight, strength, and heat resistance can improve the performance of the helicopter.
