ABSTRACT:
Translaminar reinforcement structure for localized Z-direction reinforcement of composite structure includes a body of thermally decomposable material that has substantially opposed surface, a plurality of reinforcing elements in the body that extend generally perpendicularly to one body surface, and pressure intensifying structure on the other opposed body surfaces for applying driving force to the reinforcing elements for insertion into the composite structure as the body is subjected to elevated temperature and decomposes.
