Polymeric articles filled with glass fibers are prepared by methods used in paper making, starting from aqueous dispersions of glass fibers with polyolefinic fibrils having a high surface area, by deposition in sheets, drying and pressure-molding, optionally after bonding the sheets in a sandwich-like manner with an intermediate thermoplastic polymeric plate, not containing glass fibers, and having a modulus of flexure lower than that of the glass fibers contained in such sheets, so as to thermoweld said plate to the sheets. |
