ABSTRACT:
A method of producing an object of fiber reinforced metal material, in which method a plurality of fibers or fiber bundles of a material of high strength are arranged at spaced positions, and a matrix material, preferably metal or metal alloy, is brought to closely surround each fiber or fiber bundle and is formed to a shape corresponding to the desired shape of the object. Earlier attempts to produce objects of fiber reinforced metal material have encountered problem regarding the arrangement of the fibers in a uniform pattern and in obtaining a predetermined volume fraction of the fibers in the completed object. According to the invention each fiber bundle is inserted in a tube, made of the matrix material and having suitable wall thickness to give the desired spacing between the fibers or fiber bundles, the tubes are placed in a casing, which is intended to give the object the desired outer configuration and preferably is made of the matrix material, and the casing with the tubes and fibers or fiber bundles arranged therein is subjected to hot isostatic pressing at high pressure and high temperature during an interval of time that is sufficient to give plastic deformation of the material to a substantially dense material.
