Glass Reinforcing Transparent Polycarbonate Glazing

This paper outlines a method of producing optically perfect transparent glass fiber pre-pregs. The technique uses a wetting resin in a sandwich construction with glass fibers; the construction process induces complete wetting of the fibers such that they are not visible in the resin.

The transparent pre-pregs have subsequently been laid into a mould and back-injected with polycarbonate. Results show that components produced via this method exhibit flexural rigidity three times greater than unreinforced equivalent polycarbonate mouldings.
