<p>A board which can be conformed to a desired shape, for example, when fabricating a curved wall of a boat hull or gas tank, consists of a plurality of core strips, preferably of polyurethane foam, with mating edge surfaces of complementary shape, with webs of fibrous material, for example, glass fibre matting, interposed between the mating edge surfaces and lying flat against the outer faces of the strips. The webs are held in contact with outer faces of the core strips, for example by stitching passing through outer cover sheets, also of glass fibre material. When "wetted out" with resin the board can be conformed to a desired shape by virtue of the mating edge surfaces of the core strips. The structure forms a rigid internally reinforced structure or wall when the resin is fully cured.</p> |
