The present invention relates to composite materials and the use thereof as energy resistant, for example blast-resistant, materials. Preferred aspects of the invention relate to layered composite panels comprising solid foam materials which have both a blast attenuation function and an anti-ballistic function. In further aspects, the invention provides novel composite panels which are suitable for use as blast resistant and/or anti- ballistic materials. In some examples described, the layered composite panel comprises a polymeric material (10) bonded to a first solid open-cell foam panel (12), and a cured polymeric material (14)penetrates a surface of the first solid open-cell foam panel (12).

The present invention relates to methods of manufacturing composite products having a surface effect. In some examples described, a composite product has a simulated surface, for example a stone-effect surface formed by pressing a particulate-form surface material (30) and a sheet-form curable material (40) onto a substrate (44) having an open-celled structure. In other examples, a laminate product having a veneer is formed by pressing a veneer and a sheet-form material onto a substrate including a porous structure. The veneer may comprise a wood material. In other examples, a surface effect material is bonded to a skin by pressing a sheet-form curable material to a mould surface and the surface effect material. Where the surface effect material has a high thermal conductivity, the composite product formed can feel cool to the touch.

The present invention relates to methods for forming a composite product having a patterned surface. A substrate including a porous structure (136), a sheet-form material (134) and a patterned sheet (131) are pressed together to form the composite product. In preferred examples, the patterned sheet is permeable to curable material in the sheet-form material.
A method of forming a composite product is described. An example of the method comprises providing a layer (34) comprising a sheet-form moulding material and providing a substrate (36). The layer of sheet-form material is applied onto a surface of the substrate (36); and pressed to the substrate in a mould (30). In some examples, the substrate (36) is an open celled foam and gas and/or vapour can be displaced from the pressing region.
