Resumen
The need for structural components with excellent specific stiffness and strength also at elevated temperatures results in high efforts in the development of advanced particle and fibre reinforced composites [Gadow, 2003]. With the focus on metallic matrices the highest potential to increase the specific mechanical properties are provided by fibre reinforcements. Misfits in thermal expansion coefficients lead to high normal and shear stresses at the interface, so that the mechanical properties of the composite can be reduced. During melt infiltration processes, in fibre reinforced performs, also the wettability plays a decisive role for optimized fibre incorporation [Whalen, 1975; Ebert, 1974]. Optimization of the interface means to provide sufficient fibre matrix bonding without damaging the fibres chemically or mechanically. The “solid-phase” techniques avoid fibre damage by chemical reactions, but the design of the component is strongly limited to extruded or rolled ...
