Abstract
In a process for manufacturing fiber reinforced composites made or inorganic sinterable material and inorganic fibers the fibers are continuously passed through a bath which works acccording to the fluidized bed principle and which contains a solution of at least one metal alkoxide of the elements of the first to the fourth main groups of the periodic table and the forth and fifth subgroups of the periodic table, which solution already comprises products of hydrolysis and their condensation products, and the fibers moistened with the solution are wound one upon the other to form layers, the moistened and wound fibers are dried, the metal alkoxides on the fibers are completely hydrolyzed and the products of hydrolysis are polycondensated, and the layers of the fibers being adhered by the powder and the polycondensation products of the products of hydrolysis of the metal alkoxides are hot pressed.
