A fiber and fibrous material for producing composite materials, fiber-reinforced metals, fiber-reinforced plastics and fiber-reinforced ceramics, in which short fibers, whiskers or powders made of heat resistant material are deposited on continuous fibers made of heat resistant material. The composite materials, such as fiber-reinforced metals, plastics, and ceramics, contain the fibrous material in a matrix, and have improved control of the fiber volume ratio and mechanical characteristics. Processes for producing the fiber, fibrous materials and composite materials are also disclosed.

Fibrous material for composite materials, fiber-reinforced composite

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.
