Abstract

Composite materials consisting of heat-resistant thermoplastic polymers and metal oxide reinforcing fibers having diameters of less than 1000 nm are prepared by hydrolyzing an organometallic compound, preferably an aluminum alkoxide, in a melt or solution of the thermoplastic under the action of a high shear gradient.
