Abstract
A composite resin molded product has a molded product body made of a resin and a fiber sheet material inserted on the surface of the molded product body. The fiber sheet material is formed of a knitted fabric, and the rear surface of the knitted fabric faces the molded product. The surfaces of fiber yarns of the knitted fabric are integrated with the molded product body by melting and solidifying.
Claims9
A composite resin molded product comprising:
- a molded product body made of a resin;
- and
- a fiber sheet material inserted on a surface of the molded product body, wherein:
- the fiber sheet material comprises a knitted fabric made of one single layer, and including a plurality of loops of a yarn, each loop including a pair of straight portions and a curved portion coupling the straight portions, at least surfaces of fibers constituting the yarn being made of a thermoplastic resin material;
- a rear surface of the knitted fabric of the fiber sheet material faces the molded product body;
- surfaces of fibers of the fiber sheet material are integrated with the molded product body by melting and solidifying;
- in each of the loops of the yarn forming the knitted fabric constituting the fiber sheet material, a degree of melting and solidifying at each of the straight portions is less than that at the curved portion;
- and
- the curved portions and the straight portions are included in the same loop.
