ABSTRACT:
A method of making a shaped article from at least one integrated multi-layered sheet having excellent mechanical properties and being light in weight, which includes the steps of providing a thermoplastic synthetic material reinforced by a fiber mat on at least one side of a substantially flat sheet of thermoplastic synthetic foam having a homogeneous structure, the fiber mat, thermoplastic synthetic material and sheet of synthetic foam being integrated under the influence of elevated temperature and increased pressure, providing deformability by entirely or locally heating the resulting integrated fiber reinforced sheet, giving the heated sheet the desired structure and shape, and fixing the article by cooling. The invention also includes a process starting from a sheet of a thermoplastic foam having a homogeneous structure having attached thereto at least one fiber mat impregnatd with a thermoplastic synthetic material, which includes the steps of providing deformability by entirely or locally heating the resulting integrated fiber reinforced sheet, giving the heated sheet the desired structure and shape, and fixed the article by cooling.
