[0274]A bobbin in which 16 carbon fiber bundles (T700S-12k manufactured by Toray Co., Ltd.) were wound was prepared, and the carbon fiber bundles were continuously sent out from the bobbins through the thread guide. The continuously fed carbon fiber bundles are impregnated into the impregnation die with the polyarylene sulfide copolymer supplied quantitatively from the filling feeder. The carbon fiber impregnated with the polyarylene sulfide copolymer in the impregnation die was continuously pulled out from the nozzle of the impregnation die at a pulling speed of 1 m / min using a pulling roll. The temperature at which the carbon fibers are pulled out is referred to as the processing temperature. The drawn carbon fiber bundles pass through cooling rolls, the polyarylene sulfide copolymer is cooled and solidified, and wound up on a winder as a continuous fiber-reinforced polyarylene sulfide copolymer composite base material. The obtained fiber-reinforced polyarylene sulfide copo...

[0276] The polyarylene sulfide copolymer was put into an extruder, and it was melt-kneaded at 320° C. and then extruded in a film form from a film-forming die to obtain a resin film.
[0277] As reinforcing fibers, carbon fiber bundles (T700S-12k manufactured by Toray Co., Ltd.) were cut into fibers with a length of 15 mm, and put into an air-laid device to obtain a basis weight of 100 g / m 2 , A felt-like reinforcing fiber base material in which carbon fibers are dispersed discontinuously.
[0278] The felt-like reinforcing fiber base material and the resin film were stacked in four layers so that the carbon fiber content was 30% by volume, and then put into a molding die heated to a mold temperature (processing temperature) of 320°C. Next, after heating and pressing at a pressure of 3 MPa for 10 minutes, cooling and pressing was performed at a pressure of 3 MPa to obtain a fiber-reinforced polyarylene sulfide copolymer composite base material with a thickness of 0.3 mm and a ...

[0280] Fibers having a thickness of 0.3 mm, a width of 50 mm, and a volume content of 50% of reinforcing fibers arranged in one direction were obtained in the same manner as in Example 1, except that glass fiber rovings (E glass, fiber diameter 10 μm) were used instead of carbon fiber bundles. Reinforced polyarylene sulfide copolymer composite substrate. Table 3 shows the evaluation results of the obtained fiber-reinforced polyarylene sulfide copolymer composite base material.
