Abstract
A metal/resin composite structure includes: a metal member (M) having a fine uneven surface; and a polyamide-based resin member (A) bonded to the metal member (M), and the polyamide-based resin member (A) satisfies the following condition [A1] and condition [A2]: [A1] a glass transition temperature (Tg) observed by a differential scanning calorimeter (DSC) is equal to or higher than 85° C. and equal to or lower than 140° C.; and [A2] a crystallization temperature (Tc) observed by a differential scanning calorimeter (DSC) is equal to or higher than 250° C. and equal to or lower than 292° C.

A metal/resin composite structure comprising:
- a metal member (M) having a fine uneven surface comprising a plurality of protrusions;
- and
- a polyamide-based resin member (A) bonded to the fine uneven surface of the metal member (M), wherein the polyamide-based resin member (A) is formed from a polyamide resin which comprises
- at least one semi-aromatic polyamide selected from the group consisting of polyhexamethylene isophthalamide (polyamide 6I), polyhexamethylene adipamide/polyhexamethylene isophthalamide copolymer (polyamide 66/6I), polyhexamethylene isophthalamide/polycaproamide copolymer (polyamide 6I/6), polyhexamethylene adipamide/polyhexamethylene terephthalamide/polyhexamethylene isophthalamide copolymer (polyamide 66/6T/6I), polyhexamethylene adipamide/polycaproamide/-polyhexamethylene isophthalamide copolymer (polyamide 66/6/6I), polyhexamethylene isophthalamide/polyhexamethylene terephthalamide copolymer (polyamide 6116T), and poly(2-methylpentamethylene terephthalamide)/poly(2-methylpentamethylene isophthalamide) copolymer (polyamide M5T/M5I);
- and
- at least one polyamide selected from the group consisting of polyhexamethylene terephthalamide (polyamide 6T), polyhexamethylene adipamide/polyhexamethylene terephthalamide copolymer (polyamide 66/6T), and polyhexamethylene terephthalamide/polyhexamethylene isophthalamide copolymer (polyamide 6T/6I),
- wherein the polyamide-based resin member (A) satisfies the following condition [A1] and condition [A2]:
- [A1] a glass transition temperature (Tg) observed by a differential scanning calorimeter (DSC) equal to or higher than 85° C. and equal to or lower than 140° C.;
- and
- [A2] a crystallization temperature (Tc) observed by a DSC is equal to or higher than 250° C. and equal to or lower than 292° C., and
- wherein the polyamide-based resin member (A) includes a metal soap, wherein the metal soap includes montanic acid soap and 12-hydroxystearic acid soap, and the content of the montanic acid soap relative to 100% by mass of the metal soap is more than 20% by mass and less than 100% by mass.
