1. the manufacturing approach of a fiber reinforced thermoplastic resin particle;

  • It is characterized in that, Yi Bian make many reinforcing fiber bundles each other twisted together, Yi Bian in the thermoplastic resin of fusion, reel off raw silk from cocoons;

    Thereby be formed on the wire harness that is coated with said thermoplastic resin on every side of fortifying fibre;

    This wire harness is cut into specific length and obtains particle, whereinThe melt viscosity of said thermoplastic resin is adjusted to melt flow rate (MFR)=500~

    1500g/10min,Making reinforcing fiber bundles is 0 °



    θ



    50 ° and

    said wire harness is reeled off raw silk from cocoons with respect to the twisting angle θ

    of the direction of reeling off raw silk from cocoons of said wire harness.
