1. a kind of fiber-reinforced resin sheet material, it is characterised in that:

  • It is the fiber-reinforced resin sheet material being made of composite fibre, the composite fibre by thermoplastic synthetic resin eutecticThe high-melting-point polymer ingredient of point component of polymer and thermoplastic synthetic resin is constituted;

    In the composite fibre, the content of the high-melting-point polymer ingredient is the range of 50~90 mass %, the eutecticThe range that the content of point component of polymer is 10~50 mass %;

    The low melting point polymer ingredient and the high-melting-point polymer ingredient are in polyolefin and olefin copolymerAt least one, and the high-melting-point polymer ingredient is polypropylene;

    The fiber-reinforced resin is being heated to the fusing point of the low melting point polymer ingredient less than described with sheet materialThe temperature of the fusing point of high-melting-point polymer ingredient and when carrying out compression molding and forming fiber-reinforced resin formed product, the eutecticPoint component of polymer becomes matrix resin, and the high-melting-point polymer ingredient becomes reinforcing fiber;

    The composite fibre arranges at least one direction,The fiber-reinforced resin with piece timber-used suture link, the suture be polypropylene line or core component be polypropylene andSheath ingredient is the recombination line of polyethylene.
