Abstract

Fibre composite sandwich panel made up with glass fibre reinforced polymer skins and phenolic foam core can be glued or cast together to produce a large structural beam section. To ensure the structural integrity and composite action, the sandwich panels should be effectively bonded with polymer matrix. However, the bond behaviour between sandwich panel and polymer matrix is not well understood. This paper experimentally investigated the effect of epoxy polymer matrix properties, bond length, bond thickness, and bond width on the bond behaviour, and evaluated the optimal parameters for effective bonding. The experimental program was designed by Taguchi method to reduce the number of experiments. Results showed that the polymer matrix consist with 40% filler and 60% resin (by volume) is the optimal binder. A bond length of at least 70 mm and bond thickness of 5 mm were found effectively to utilise the strength of the composite sandwich panel. The bond width however has insignificant effect on the bond strength.
