(57) [Abstract] [Object] An object of the present invention is to provide a glass fiber capable of improving the tracking resistance and hydrolysis resistance of an FRTP molded product, and a glass fiber reinforced using the glass fiber as a reinforcing material. It is to provide a thermoplastic resin. [Structure] Polytetrafluoroethylene dispersion 3% by mass, phenol novolak type epoxy emulsion 4% by mass, non-yellowing type urethane emulsion 2% by mass, γ-aminopropyltriethoxysilane 1% by mass, A sizing agent consisting of 90% by mass of deionized water was prepared, and then the sizing agent was applied to the glass fiber surface in a spinning process in which 2,000 glass fibers (filaments) having a diameter of 13 μm were bundled into strands. Next, this strand was cut into a length of 3 mm and dried to obtain a glass chopped strand. |
