  • Patent number: 4740428
    Abstract: This invention relates to a fiber-reinforced metallic member in which an essential part is reinforced by inorganic fibers. The fiber-reinforced metallic member is reinforced by means of a fiber shaped body having a low fiber volume proportion which is formed by mixing powder having the same composition as the metal forming a non-reinforced layer thereof or powder consisting of principal components of the metal with inorganic fibers, the particle diameter of the powder being 1 to 20 times as large as a diameter of the inorganic fibers, and compressing and shaping the mixture. It is also possible to place the layer which is reinforced by the fiber shaped body having a low fiber volume proportion, adjacent to the non-reinforced layer, and to increase a fiber volume proportion in the reinforced layer in the direction of separating from the adjacent reinforced layer.
