A Global Approach to Fiber nD Architectures and Self‐Sealing Matrices: From Research to Production

Abstract

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 Propulsion Solide is based on continuous fiber‐reinforced composites and carbon or ceramics matrices deposited by chemical vapor infiltration. This article presents a status of the latest improvements for cost savings of composite reinforcements (so‐called texture) and specific matrices developed to increase both durability and temperature capability of previous ceramic composites, operating in oxidative environments.
