Abstract:
1. A layered product comprising a prepreg obtained by impregnating unidirectional carbon fiber bundles used as reinforcing fibers with a thermosetting resin; and a base material for thermal bonding which is arranged in a region of a surface of said prepreg to be thermally bonded, and wherein said base material for thermal bonding comprises a polyamide resin selected from the group consisting of polyamide 11, polyamide 12, polyamide 610, polyamide 612, polyamide 66/6, polyamide 6/66/610, polyamide 6/66/612, polyamide 6/66/610/612, and polyamide 6/6I as a thermoplastic resin, wherein the bonding strength (S) of a test piece including the base material for thermal bonding, based on the Testing Method of Strength Properties of Adhesives in Shear by Tension Loading according to ISO 4587 is 5.0 MPa or higher at a temperature of 100 C and 1.0 MPa or lower at a temperature of 200 C.
