- Abstract
Describes a new concept aimed at increasing the compression strength after impact properties of laminated-graphite systems by periodically interleaving solid thermoplastic thin films into the graphite plies. Success of the concept in many epoxy-based laminates; Compatibility of the thermosetting polyimide LP-15 and thermoplastic toughening agent PEK-C to form polymeric blend for a wide range of composition ratios; Detection of the superiority of the toughness improvement obtained by powder coating to that by film interleaving and in far distance to the overall concept.
