Abstract: This invention relates to composite articles of manufacture and to a method for the preparation of these articles. The articles are impact-resistant, three-dimensional and rigid. The articles are comprised of two essential elements: (1) A pliable, hollow premolded outer plastics layer and (2) an essentially rigid non-cellular organic plastics structural backing member solidified in the hollow interior of the plastics skin, and essentially solidly filling said hollow interior. The hollow outer layer is prepared in a manner to have an access opening to its hollow interior. A liquid plastics composition is next prepared in a separate step that comprises an organic binder which solidifies at room temperature, in most cases by converting to a thermoset stage. This liquid composition is then introduced through the access opening into the cavity of the premolded outer layer.
