US 11,773,296 B2 · Method for curing adhesive composition and method for manufacturing bonded structure

Abstract

A method for curing an adhesive composition includes: arranging an adhesive composition that transmits laser light of a first wavelength in contact with a surface of a first adherend that contains, at least at its surface, a first light-to-heat conversion material that generates heat by absorbing laser light of the first wavelength; and curing the adhesive composition by irradiating the adhesive composition and the first adherend with laser light of the first wavelength. In a method for manufacturing a bonded structure, a first bonded structure is manufactured by bonding the adhesive composition to the first adherend by using the method for curing an adhesive composition.

A method for curing an adhesive composition, comprising:

arranging an adhesive composition that transmits laser light of a first wavelength in contact with a surface of a first adherend that contains, at least at its surface, a first material that generates heat by absorbing laser light of the first wavelength;
and
curing the adhesive composition by irradiating the adhesive composition and the first adherend with laser light of the first wavelength, wherein
the adhesive composition contains a second material that changes, when heated, to a material that generates heat by absorbing laser light of the first wavelength.
