Method for manufacturing fiber-reinforced resin composite, fiber-reinforced resin composite and molded product

A method for manufacturing a fiber-reinforced resin composite comprising the steps of:

• spinning a plurality of fiber filaments, wherein the plurality of fiber filaments is spun at a speed of from 600 m/min to 700 m/min and the plurality of fiber filaments is an inorganic fiber made of at least one selected from the group of glass fiber, carbon fiber, and a combination thereof;
• coating a surface of each of the plurality of fiber filaments by spraying an impregnation resin emulsion onto the plurality of spun fiber filaments, wherein a viscosity of the impregnation resin emulsion is measured by using a Brookfield viscometer and ranges from 6,000 cP to 10,000 cP at 25° C.;
• and
• forming a fiber strand by bundling the plurality of fiber filaments coated with the impregnation resin emulsion, wherein the fiber strand is the fiber-reinforced resin composite, and a separation distance between the plurality of fiber filaments present in impregnation resin ranging from 0.5 μm to 3.62 μm,
• wherein the method does not comprise opening or widening the bound fiber strand and the method does not comprise passing or immersing the fiber strand through or in a separate resin impregnation bath.
