<p>A composite laminated article comprising: a first layer 4 of a closed cell foam of a thermoplastic material, a second layer 6 of a fibre-reinforced resin, the resin adhering a surface of the second layer to a surface of the first layer, wherein the closed cell foam has an average cell size less than 100 microns. The closed cell foam may comprise a plurality of expanded beads having an average size of 2 to 4 mm mutually bonded together. It may comprise a blend of polystyrene and polyphenylene oxide (PS/PPO). The fibre reinforced resin may comprise epoxy resin. Channels 20 or conduits 22 may be present along which resin may flow. The resin required for bonding a foam core to a fibre reinforced layer is thus minimized as also weight and material whilst still achieving a given structural performance providing particular mechanical properties. The laminated article may be used for manufacturing wind turbine blades, boat hulls, decks and bulkheads.</p> |
