Abstract
A method includes contacting a treatment composition including a permanganic acid to a surface of a first substrate to form a treated substrate surface, wherein the first substrate comprises a polyarylenesulfide. The method further includes adhesively bonding the treated substrate surface to a second substrate surface. An associated kit is also provided
Claims28
A method, comprising:
- contacting a treatment composition comprising a permanganic acid to a surface of a first substrate to form a treated substrate surface, wherein the first substrate comprises a polyarylenesulfide;
- and
- adhesively bonding the treated substrate surface to a second substrate surface.
A surface treatment kit, comprising:
- a treatment composition comprising permanganic acid;
- and
- an instruction set for treating a surface of a substrate comprising a polyarylenesulfide with the treatment composition.
A method, comprising:
- contacting a surface of a damaged aircraft thermoplastic composite structure with a treatment composition that comprises an oxidizing acid selected from the group consisting of permanganic acid, nitric acid, and both nitric acid and permanganic acid;
- applying an adhesive layer to at least a portion of the treated surface;
- and
- contacting a repair patch to the adhesive layer.
