  • Transparent composites and laminates and methods for making
    Patent number: 8753464
    Abstract: An exemplary method for making a transparent composite includes steps of combining a refractive index modifier with a precursor solution to provide a modified polymer precursor solution, combining glass with the modified precursor solution, and curing the modified precursor solution to create a transparent glass reinforced polymer composite. An example refractive index modifier comprises a monofunctional compound or monofunctional monomer, a polyfunctional compound or polyfunctional monomer or polymer, which is combined with the polymer precursor solution to increase the crosslinking density of the chain in the cured modified polymer precursor solution, and thus increase the refractive index. An exemplary transparent composite comprises a glass reinforced thermosetting polymer composite layer sandwiched between glass layers.
    Type: Grant
