Abstract
Boron fibre reinforced aluminium composite was produced by a resistance sintering process. A mixture of atomized aluminium powder (-150 mesh) and boron fibre (200 μm in diameter, tensile strength 320 kg/mm2) was resistance-sintered for 1.2-1.5 sec. When a composite was produced with appropriate power input so that the aluminium matrix does not fuse excessively, a sound fibre-matrix interface without a reaction layer could be formed and the mechanical properties of the obtained composite was excellent (for example, Al-20 vol%B: 50 kg/mm2).
