Abstract

A direct casting process for the production of a low-stress composite article e.g. a lens comprising a glass element bonded to a high-shrinkage thermosetting plastic element comprises: -coating selected surface portions of the glass element with a thermoplastic adhesive having a heat sealing temperature above the minimum curing temperature of the thermosetting plastic; -casting the thermosetting plastic in liquid form against the surface portions of the glass element which have been coated with the thermoplastic adhesive; -curing the thermosetting plastic by heating the plastic, the glass element and the thermoplastic adhesive to a temperature below the heat sealing temperature of the thermoplastic adhesive, but above the minimum curing temperature of the thermosetting plastic; and -consolidating the cured thermosetting plastic, thermoplastic adhesive and glass element into a unitary glass/plastic composite by heating them to a temperature above the heat sealing temperature of the thermoplastic adhesive. r
