Abstract
A method of manufacturing fiber-reinforced composites from a fibrous material, includes the steps of infiltrating the fibrous material with material from which a matrix is built up; preforming the infiltrated fibrous material into a green body against as shape-imparting body; encapsulating the preformed green body and shape-imparting body; consolidating and sintering the encapsulated green body by means of isostatic pressure sintering into an essentially dense composite body while preventing deformation of the green body with the shape-imparting body; and removing the encapsulated green body and shape-imparting body after isostatic pressure sintering.
