HIGHLY FILLED PARTICULATE COMPOSITE MATERIALS AND METHODS AND APPARATUS FOR MAKING SAME

摘要

A composition comprising a high volumetric loading of near spherical particles in a high temperature matrix is disclosed. The matrix material encapsulates the solid particulate material, wherein each individual particle of the solid particulate material is in close contact with an average of at least (6) adjacent particles. A method comprising providing a solid particulate material, providing a mold, providing a means for packing the particles in the mold to provide the high packing density which may include : evacuating the solid particulate material of gas in the void spaces between the particles of the particulate material, evacuating the mold, introducing the evacuated solid particulate material into the mold, providing a fluid matrix material, and introducing the fluid matrix material into the void spaces while constraining the solid particulate material.
