The competence center for composite materials & processes meets the challenges of industrial competitiveness to develop lighter aeronautical and spatial structures that are both resistant and multifunctional by using high performance composite materials. It focuses on the development of materials from thermostable organic matrices (PEEK, PEKK, PAEK, high temperature polymers), thermoplastics or thermosets, and from ceramic matrices (aluminum oxide Al2O3, silicon carbide SiC) resistant at very high temperatures.
The applications targeted are the critical mechanical structures of aircraft, launchers, satellites and motors whose reliability has to be guaranteed in all circumstances.
The competence center designs, develops and operates on a semi-industrial scale. Going beyond the technological error testing approach often found in industry, the competence center develops modeling tools for materials and processes to understand the influence of setting parameters of development means on the micro-structure and properties of materials.
It develops the skills of technicians, engineers and PhDs, and trains PhD students for careers in the formulation and the implementation of new generation high-performance composites.
The research deals with:
- the formulation and the deposition of sizing adapted to thermoplastic matrices
- the formulation of high temperature heat hardened prepregs and thermoplastics
- the integration of electrically conductive particles
- the introduction of piezoelectric charges in the polymer films (vibration damping)
- the integration of sensors for structural health monitoring or electrical power conductors
 A prepreg is a half-finished product formed of a matrix impregnating a reinforcement that ensure high breaking strength. The matrix may be thermoset or thermoplastic resins impregnated with reinforcement fibers (glass fibers, fabric, carbon fibers) This highly charged composite is earmarked for hot molding under pressure to manufacture a finished product. In the case of CMC the matrix is a ceramic powder the reinforcement in ceramic or carbon fibers). This composite highly charged in ceramic particles of low gran size is then consolidated at high temperature to manufacture a finished product.
