Abstract:
A fiber-composite material comprising:a plurality of first yarns arranged in a first layer, each first yarn extending in a first longitudinal direction, and comprising a bundle of carbon fibers and an additional carbon component; a plurality of second yarns arranged in a second layer, each second layer extending in a second longitudinal direction and comprising a bundle of carbon fibers and an additional carbon component, said second longitudinal direction being substantially perpendicular to said first longitudinal direction; and a Siâ€”SiC matrix for three-dimensional integrating the yarns to one another, said matrix being interposed between adjacent yarns within each layer and between yarns of adjacent layers; wherein said fiber-composite material is formed by a method comprising the steps of: forming a plastic coating around each of said first and second yarns; stacking the plurality of first and second yarns on one another along said first and second longitudinal directions, respectively, to form an intermediate product; heating the intermediate product to burn the plastic coatings and form a burned product; and infiltrating molten silicon into the pores of the burned product to form said fiber-composite material.
