Fibrous material for composite materials, fiber-reinforced metal produced therefrom, and process for producing same

DETAILED DESCRIPTION The present invention eliminates the above-mentioned disadvantages in the prior art technology.
Accordingly, it is an object of the invention to provide a reinforcing fibrous material for composite materials and a process for producing same.
The reinforcing fibrous material has an improved wettability with the matrix metal when used for FRM.
The reinforcing fibrous material can be evenly dispersed in the composite material at a properly controlled fiber volume ratio.
The reinforcing fibrous material may be composed of different kinds of continuous filament fibers, in which case the reinforcing fibrous material improves the mechanical properties of the composite material through the reduction of thermal stress between the continuous filament fibers and the matrix.
It is another object of the invention to provide a fiber reinforced metal and a process for producing same.
The fiber reinforced metal has improved mechanical properties such as low anisotropy and residual stress and good abrasion resistance.
It is formed by evenly dispersing continuous filament fibers in a matrix metal, with a controlled fiber volume ratio.
The improved mechanical properties are obtained by combining continuous filament fibers with short fibers, whiskers, or powders of different properties.
