Cost-Effectiveness Concept applied to the development of advanced materials

Abstract Now that the aerospace industry is no longer a dream, but a promising market, high performance structural materials are in great need. For such applications, Ceramic Matrix Composites (CMCs) are hopeful candidates. However, one of the most important problems actually hindering CMC research and development is the high cost of common process routes. To try to solve such problem, a new concept for the R&D of advanced materials such as CMCs is proposed, namely, the Cost-Effectiveness Concept (CEC). This concept is one way to bring together scientific and technological targets. In this work, this strategy will be defined and then illustrated in the case of the elaboration of 3D CMCs and of the development of oxidation protection materials.
