Abstract
A method and apparatus for manufacturing composite materials. In a first embodiment, a binding material is placed on a heat-resistant filter that is placed on hollow particles in a pressurizable container. Under pressure and heat, the binding material flows through the filter and infiltrates the spaces between the hollow particles. In a further embodiment, composite material wire is produced by coating the surfaces of inorganic fiber bundles with a metal oxide by dipping in a solution of a hydrolyzable organic metal compound and hydrolyzing and heat-treating prior to continuous infiltration under pressure. In a further embodiment, the apparatus includes orifices with enlarged diameter sections. In a still further embodiment, an apparatus is provided with ultrasonic vibration.
