摘要

A method for manufacturing shaped articles by moulding, said method comprising the steps of providing a mould conforming to a desired shape, introducing into the mould a fabric, which is dimensionally stable under first temperature conditions but is able to yield under second temperature conditions, said fabric containing or consisting at least partly of polyethylene and/or polypropylene and/or polystyrene, and expandable polyethylene and/or polypropylene and/or polystyrene, which will expand under said second temperature conditions, and heating the mould containing said fabric and said expandable polyethylene and/or polypropylene and/or polystyrene to said second temperature conditions.
