US 2011/0033710 A1 · COMPOSITE STRUCTURES OF A METAL COMPONENT WITH A RESIN COMPONENT AND ARTICLES THEREOF

Abstract

The present invention aims at providing an article having a composite structure including a metal component and a resin component bonded together. The present invention provides an article which is a composite structure, including a first component and s second component, the first component is a metal substrate and the second component is a molded product comprising a thermoplastic resin composition, and the reaction of a silane coupling compound resin with the metal substrate for forming binder between the first and second components comprising SiOx, C—Si—O—X bond (X is metallic substance of the first component) as determined by x-ray photoelectron spectroscopy, wherein the bonding strength between the first and second components is about 30 Mpa or more.

Dependent claims

A composite structure comprising:

a) a first component comprising a metal substrate;
b) a second component comprising a thermoplastic resin composition;
and
c) a silane coupling compound applied to said metal substrate of said first component, to form a binder between said first component and said second component, said binder comprising a SiOx, C—Si—O—X bond (wherein X is the metallic substance of said metal substrate of said first component) as determined by x-ray photoelectron spectroscopy, wherein the ratio of the SiOx, C—Si—O—X bond strength and the metal bond strength is over 0.08, and further wherein the bonding strength between said first component and said second component is greater than or equal to about 30 Mpa.
