A process for forming a shaped prelaminate of glass and plastic by a) drawing an assembly of plastic layers against a hot, contoured, e.g. of compound curvature, mold surface to provide a shaped plastic preform at elevated temperature; b) transferring the shaped preform without cooling to an adjacent unheated glass layer of substantially matching surface contour to heat bond the shaped plastic preform to the glass layer; and then c) removing heat from the shaped plastic preform via conductive heat transfer to the glass layer to form the shaped prelaminate of glass and plastic layers. A bilayer glazing panel is formed in a conventional unmodified autoclave bonding system by exposing the prelaminate to elevated temperature and pressure to firmly bond the plastic to the glass.
