An aluminum-based metal-resin composite structure, an aluminum-based metal member, a manufacturing method of an aluminum-based metal member, and a manufacturing method of an aluminum-based metal-resin composite structure

摘要

An aluminum-based metal member 103 having a dendritic layer 103-2 formed on at least a part of its surface, and an aluminum-based metal member 103 are joined through a dendritic layer 103-2, and made of a thermoplastic resin composition. It is an aluminum-based metal-resin composite structure 106 including a resin member 105, and at least the junction surface 104 of the aluminum-based metal member 103 with the resin member 105 is measured using a Fourier transform infrared spectrophotometer (FTIR). analysis, as the absorbance of an absorption peak as measured by a 3400㎝ -11 a, and referred to as the absorbance of the 3400㎝ -1 of the straight line connecting the absorbance of the absorbance and 2500㎝ 3800㎝ -1-10 a When the absorbance difference (A 1 -A 0 ) is in the range of 0.03 or less, the aluminum-based metal resin composite structure.
