FORCE is relevant to the development of damage-tolerant and oxidation resistant materials for use at high temperature in oxidizing atmospheres. The basis objective is the development of novel buffer layers able to prevent fibers degradation during sintering and oxidation, which will be fundamental for the design and production of functionally graded ultra-high temperature composites (FG-UHTC) containing short carbon fibers with enhanced thermo-mechanical properties for applications under extreme environments.
