NOVEL METHODS FOR MAKING PREFORMS FOR COMPOSITE FORMATION PROCESSES

摘要

The present invention relates to novel methods for shaping a filler material into a porous preform and subsequently filling at least a portion of the porous preform with a second material to form a composite body. Specific aspects of the invention include novel combinations of materials to form the preform in combination with novel processing techniques for shaping the combinations of materials into a porous preform.
