Abstract

The need for new materials for structural applications at ultra-high temperatures (1000 - 2000 C), under high thermal gradients and aggressive environments renders the investigation of ceramic materials and ceramic matrix composites (CMCs) very interesting, and even fundamental to the development and realisation of many future technologies. The material described and characterised in this study is a 2D CMC made of carbon fibre in a SiC matrix. Composites of this type are being developed for use in several components of aerospace engines and thermal shields of spacecraft. This work presents values of elastic moduli determined by different methods, and also describes the tensile and mechanical fatigue behaviour of the material at room temperature.
