The field of application of oxidic fibre composite ceramics (O-CMC) is constantly expanding. This material class is established in many special high-temperature applications for which only small quantities are required. Potential applications, such as components for gas turbines, will go beyond the scale of small series production. In future, such components will have to be produced using series production technologies that have not been available to date.
The project was to develop a prepreg technology suitable for series production, preferably based on established processes from CFRP production, with which O-CMC components can be used for sintering and bonding.
temperatures < 1200 °C can be produced. The requirements for O-CMC materials made of Al2O3 fibres and a matrix system of Al2O3-ZrO2 were bending strength > 200 MPa, interlaminar shear strength > 14 MPa and elongation at break > 0.3 %. The mechanical properties of the O-CMC components manufactured on the basis of the prepreg technology developed were to have a significantly lower scattering and thus higher reproducibility than components currently manufactured by hand.
