Title: LAMINATED COMPOSITE MATERIAL AND METHOD FOR MANUFACTURING LAMINATED COMPOSITE MATERIAL
Abstract:
A laminated composite material has a core, skin layers and adhesive mat layers provided between the core and the respective skin layers at each side of the core. Each adhesive mat layer comprises a network of natural fibres at least partially impregnated with a resin- based binder component, the resin-based binder component bonding to the core and to the skin layers. The skin layers comprise paper. The skin layer has sub-layers, at least one of these sub-layers being a paper sub-layer. The skin layer includes at least one moisture-resistant sub-layer. The skin layer has a moisture resistance which is expressed in terms of Water Vapour Transmission Rate (WVTR) which is not more than 24 g/m2 x d at 23°C, 85% r.h. (grams of water per m2 permeating over a 24 hour period).
