Research and development at LAC/BIAM has focused on polymer matrix composite system possessing excellent damage resistance and processing ease for aerospace industry.The goal has been achieved by development of an innovative toughening technology platform,so-called Ex-situ concept,both for prepreg-autoclave and liquid molding technique like RTM and RFI.High-performance epoxy and bismaleimide matrix composites have been developed by using the LAC/BIAM's proprietary concept.Processing conditions and mechanical properties of the trial products have been demonstrated.Particularly the interlaminar toughness and impact damage resistance and tolerance have been significantly improved,with balanced in-plane properties even at hot/wet conditions and excellent processabilities.
