Interleaved Bismaleimide Composites

Abstract

This report examines interleaving as a technique for the improvement of delamination resistance in composites. In particular, the influence of the deformation behavior of the interleaf film and film adhesion on composite fracture energy is studied. Teflon, E, and Kapton interleaf film materials are compared. Kapton and E films display predominantly brittle deformation behavior. Teflon exhibits substantial deformation before failure. All films are plasma treated to vary film-resin bond strengths. With the Kapton and Teflon films, plasma treatments are shown to increase film-resin adhesion and fracture energy. The effectiveness of Teflon as an interleaf material may be limited by the toughness of this film. Film-resin adhesion with the E film is determined to be optimized. Fracture energy is greatest with composites interleaved with the E film. Polymer matrix composites, Interleaved composites, Plasma treatment, Bismaleimide
