Method and apparatus of manufacturing resin composite material

A method of manufacturing a resin composite material, comprising steps of:

• (2a) supplying a thermoplastic resin from a resin supply portion to a first cylinder;
• (2b) melting and plasticizing the thermoplastic resin;
• (2c) supplying a moisture-absorbent filler from a moisture-absorbent filler supply portion into the first cylinder, and kneading the moisture-absorbent filler with the thermoplastic resin melted and plasticized;
• (2d) conveying a kneaded material obtained by the kneading through the first cylinder;
• and
• (2e) extruding the conveyed kneaded material from a die provided in the first cylinder to manufacture a composite material of the moisture-absorbent filler/the thermoplastic resin,
• wherein, in step (2c), volatile gas generated from the kneaded material is degassed to outside from a first degassing portion provided at a connection part of the moisture-absorbent filler supply portion with the first cylinder,
• wherein the volatile gas is water vapor that is vaporized by heating moisture contained in the moisture-absorbent filler, and
• wherein a “gas component originating from the kneaded material” generated by decomposition of the moisture-absorbent filler when heated to a temperature equal to or higher than a roasting temperature is degassed to the outside through a second degassing portion different from the first degassing portion.
