Abstract
This specification relates to a colorless composite material capable of retaining transparency within a wide temperature range by impregnating glass composition (glass fibers) with inorganic-organic hybrid resin. A colorless composite material according to exemplary embodiments includes glass fibers, and inorganic-organic hybrid resin consisting of inorganic bonds and organic bonds, wherein the inorganic bonds are Si—O—Si bonds or Si—O-M bonds and M denotes a metallic element.
Claims1
A colorless composite material comprising:
- glass fibers;
- and
- inorganic-organic hybrid resin consisting of inorganic bonds and organic bonds,
- wherein the inorganic bonds are Si—O-M bonds, and M is one of Ti, Zr and Al,
- with the proviso that when the Si-O-M bond is the Si—O-Ti bond, the amount of Ti is 2% to 20% by weight,
- when the Si—O-M bond is the Si—O-Zr bond, the amount of Zr is 2% to 8% by weight, and
- when the Si—O-M bond is the Si—O-Al bond, the amount of Al is 2% to 10% by weight,
- all weight percentages being based on the total weight of the inorganic-organic hybrid resin, and
- wherein the inorganic-organic hybrid resin has a thermooptic coefficient of −5×10−5/° C.˜+10−5/° C.
