ABSTRACT:
A process is described for producing fiber-reinforced light-metal castings in which a loose fiber tangle is placed in a casting mold and is saturated with molten light-metal under low pressure. Subsequently, the excess of molten light-metal is squeezed off while the fiber tangle is compressed. The outflow of the molten light-metal is then stopped with the molten light-metal being solidified under high pressure. The process is especially suitable for utilizing the solution-spun inorganic fiber tangles that up to now had not been especially suitable for the reinforcing of light-metals.
