Abstract

A process has been developed which allows the adjustment of fibre volume fraction in a range from 30 to 60 vol.-% for unidirectionally long fibre reinforced metal matrix composites (MMCs). An impregnation method with a water-particle suspension is used to introduce ceramic particles as spacers in a carbon fibre roving. The amount of particles and the resulting fibre volume fraction can be varied by changing process, tooling and material parameters. The main parameters influencing the fibre volume fraction are the roving winding speed, the particle concentration and particle size. After fabrication the fibre preforms are infiltrated by a gas pressure infiltration technique with the magnesium alloy AM20 and characterised mechanically (Young modulus, tensile and bending strength) as well as physically (thermal expansion). In conclusion a locally fibre reinforced shaped part with a graded fibre content is presented.
