PREFORM FOR COMPOSITES HAVING DISCONTINUOUS REINFORCING AGENTS WITH IMPROVED RIGIDITY AND STRENGTH, AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A preform for composite having discontinuous reinforcing agents is provided to reduce failure rate remarkably by improving strength and rigidity, thereby improving productivity.;CONSTITUTION: A preform(10) for composite having discontinuous reinforcements comprises a 2D-preform(12) and a plurality of reinforcing agents(14). A 2D perform is laminated by multi-layer. A plurality of reinforcing agents are inserted into the one end of the inside of the 2D perform along the laminated direction.;COPYRIGHT KIPO 2012
