Abstract

Laminated composites made with layers of fiber reinforced thermosetting resin prepregs and with thermoplastic film interleaf layers are improved by using thermoplastic film coated with thermosetting adhesive as the interleaf layer. In composites having a honeycomb core with thermosetting prepreg skins, the thermoplastic film is a moisture barrier to exclude water vapor from the honeycomb cavities.
