TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The metal alkoxide is silane alkoxide, zirconium alkoxide, titanium alkoxide and/or aluminum alkoxide, preferably silane alkoxide, which is a mixture of a reactive silane compound of formula: (R3)y-Si-(OR2)4-y, or silane compounds of formula: (R1)x-Si-(OR2)4-x and/or their partial condensate.R1 = CH3 or C6H5;R2 = CH3 or C2H5;x = 0-2;y = 1 or 2; andR3 = organic chain having functional group, which reacts with thermosetting resin by carrying out heat bonding.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The metal alkoxide is silane alkoxide, zirconium alkoxide, titanium alkoxide and/or aluminum alkoxide, preferably silane alkoxide, which is a mixture of a reactive silane compound of formula: (R3)y-Si-(OR2)4-y, or silane compounds of formula: (R1)x-Si-(OR2)4-x and/or their partial condensate.R1 = CH3 or C6H5;R2 = CH3 or C2H5;x = 0-2;y = 1 or 2; andR3 = organic chain having functional group, which reacts with thermosetting resin by carrying out heat bonding.    TECHNOLOGY FOCUS - POLYMERS - Preferred Resin: The organic-inorganic hybrid resin contains at least one type of fluorene group-containing resin and at least one type of metal alkoxide of formula: (C6H5)z-Si-(OR2)4-z.R2 = same as defined above;andz = 1 or 2.The fluorene group-containing resin is a fluorene group-containing epoxy resin.CERAMIC AND GLASS - Preferred Component: The glass cloth is a E glass. EXAMPLE - A resin varnish was prepared using BPEF-G (bisphenoxy ethanol fluorene diglycidyl ether) (in g) (16), tetrahydrofuran (16), M silicate 51 (methoxy polysiloxane) (12), 3-glycidoxy propyl triethoxysilane (32), 10 wt.% formic acid aqueous solution (5) and Adeka Optomer SP-150 (photocuring agent) (1). The resin varnish was impregnated into Style 1080 (glass cloth having refractive index of 1.57 and thickness of 50 microns and containing E-glass fiber), and solvent was vaporized at 60degreesC. The resin impregnated glass cloth was photocured using ultraviolet irradiation device, heated at 100degreesC for 1 hour, and press molded at 150degreesC for 1 hour, to obtain a transparent hybrid sheet. The hybrid sheet had thickness of 100 microns and total light transmittance of 90% measured according to JIS K-7105.
