A Global Approach To Fibre Nd Architectures And Self-Sealing Matrices: From Research To Production

Thermostructural composites (TSC) improvement is one of the key factors to ensure future competitiveness of aeronautical and space engines. The TSC technology developed in Snecma is based on continuous fibre-reinforced composites and carbon or ceramics matrices deposited by chemical vapour infiltration. This article presents a status of the latest improvements for cost savings of composite reinforcements and specific matrices developed to increase both durability and temperature capability of previous ceramic composites, operating in oxidative environments.
