Patent ID: 8372504

Claim:
A transparent composite comprising: a transparent crosslinked siloxane resin produced by non-hydrolytic condensation, wherein the transparent crosslinked siloxane resin is at least one resin selected from the group consisting of: (1) a resin having Si—O (siloxane) bonds produced by non-hydrolytic condensation of reactants containing organoalkoxysilane and organosilanediol; (2) a resin having at least two kinds of heterometal bonds, including Si—O (siloxane) bonds, produced by non-hydrolytic condensation of reactants containing a mixture of organoalkoxysilane with metal alkoxide, and organosilanediol; and (3) a resin produced by non-hydrolytic condensation of reactants containing the above reactants and a reactive additive; and a glass fabric, wherein the glass fabric is impregnated with the transparent siloxane resin, wherein a difference in refractive indices between the siloxane resin and the glass fabric is 0.01 or less, and wherein the transparent composite has a transmission of 80% to 100% to light with a wavelength of 550 nm, and a thermal expansion coefficient of 30 ppm/° C. or less at a temperature of about 30° C. to about 200° C., and wherein the transparent composite is directed to providing a substrate for thin film transistor (TFT) devices, display devices or optical devices.
