Abstract
The present invention relates to a fibrous material for composite materials, a fiber-reinforced metal produced therefrom, and a process for producing same. The fibrous material is composed of continuous filament fibers selected from heat resistant substances and short fibers, whiskers, or powders selected from heat resistant substances. The fiber-reinforced metal is composed of the fibrous material and a matrix metal, has a reduced anisotropy of mechanical properties, and can be made at my desired fiber volume ratio.
Claims17
A process for producing a fibrous material for composite materials, comprising:
- loosening a bundle of individual continuous fibers made of at least one heat resistant substance selected from the group consisting of ceramics, carbon, metals and intermetallic compounds, and
- dipping said bundle of individual continuous fibers in a bath containing a suspending medium and short fibers, whiskers, or powders made of at least one heat resistant substance selected from the group consisting of ceramics, carbon, metals and intermetallic compounds,
- thereby attaching said short fibers, whiskers, or powders to a surface of the individual continuous fibers.
