Method/apparatus for making a composite wherein reinforcement or filler material, such as, for example, ceramic fibers or whiskers, are confined in a microwave-transparent envelope, the reinforcement or filler material is microwave heated, and a gaseous reactant stream is flowed through the envelope so as to infiltrate interstices of the heated reinforcement or filler material and chemically vapor deposit a matrix, such as a ceramic matrix, from the interior toward the exterior of the heated material. The envelope imparts a desired shape and size to the composite. After infiltration, the envelope typically is removed from the composite.
