Abstract
To provide a glass fiber which can improve the refractive index of the glass fiber to the same level as a polycarbonate and maintain the transmittance of a molded product after the fiber is reinforced, and a glass fiber-reinforced polycarbonate resin molded product using the glass fiber. A glass fiber to be used as a glass fiber for reinforcing a polycarbonate resin comprising, as inorganic components in whole glass fiber, from 50 to 60 mass % of SiO, from 10 to 15 mass % of AlO, from 15 to 25 mass % of CaO, from 2 to 10 mass % of TiO, from 2 to 8 mass % of BO, from 0 to 5 mass % of MgO, from 0 to 5 mass % of ZnO, from 0 to 5 mass % of BaO, from 0 to 5 mass % of ZrO, from 0 to 2 mass % of LiO, from 0 to 2 mass % of NaO and from 0 to 2 mass % of KO, wherein the total content of the above LiO, NaO and KO is from 0 to 2 mass % based on the above whole glass fiber, and the refractive index of the above glass fiber is from 1.580 to 1.590.
