The difficulty of producing composite materials in profiled form is overcome by the provision of a composite material in which a relatively thick core layer (9) comprises a continuous array of open polyhedral frames (10), which frames are bonded at their outermost points to a relatively thin outer layer or layers (7, 8) of a durable, high strength material. The array of frames may be produced by distortion of a suitable expanded metal sheet comprising a two-dimensional network of polygons. The core layer is of relatively high strength and low weight, and can be performed into desired shapes, allowing for ease of production of profiled composite materials. The invention also provides a method of manufacture of such a material, and a structure and a composite panel formed from the material. The material is of use for purposes such as cladding, flooring and panelling, for instance in the building industry. |
