Method of manufacturing articles utilizing a composite material having a high density of small particles in a matrix material

摘要

A method of manufacturing articles utilizing a composite material having a high density of small particles such as microspheres in a matrix material is disclosed. In accordance with one aspect of the present invention, at least first and second layers of flanking material are disposed in a generally non-parallel relationship with respect to each other and then are pulled through a die. While the flanking material layers are being pulled through the die, a composite material is injected into a space defined between the at least first and second layers of flanking material. The composite material and the at least first and second layers of flanking material are heated as they pass through the die to cure the composite material and bond the at least two flanking material layers to the composite material, thereby forming a cured article.
