Title:
複合構造体およびその製造方法
Document Type and Number:
Japanese Patent JP6819798
Kind Code:
B2
Abstract:
Provided are a composite structure that is formed by joining a metal member and a molded article of a polyarylene sulfide resin composition and is more excellent in terms of joint strength and heat cycle resistance and a producing method therefor. More specifically, provided are a composite structure formed by joining a surface-roughened metal member and a PPS member, in which a number average value of developed area ratios (Sdr) of an interface measured at five random points on a surface of the surface-roughened metal member using a confocal microscope based on ISO 25178 is 5 [%] or more, and a melt viscosity of a PPS resin is 15 to 500 [Pa·s], and a producing method therefor.
