Abstract
Curable mechanical fasteners of the invention comprise a fastening surface comprising a curable material, wherein the fastening surface is capable of being repeatedly attached and unattached to a complementary fastening surface, and when attached to the complementary fastening surface and cured, the curable mechanical fastener is capable of becoming permanently attached to the complementary fastening surface. The curable mechanical fastener may also further comprise the complementary fastening surface.
Claims24
A curable mechanical fastener comprising:
- a fastener consisting of a curable material with a fastening surface, and
- a complementary fastening surface,
- wherein the curable material comprises a combination of at least one thermosettable composition and at least one thermoplastic composition;
- and
- wherein the fastening surface is capable of being repeatedly attached and unattached to the complementary fastening surface, and wherein the fastening surface is capable of becoming permanently attached to the complementary fastening surface when cured.
A curable mechanical fastener comprising:
- a fastening surface comprising a plurality of fastening elements consisting of a curable material coupled to a backing, and
- a complementary fastening surface,
- wherein the fastening surface is capable of being repeatedly attached and unattached to the complementary fastening surface, and wherein the fastening surface is capable of becoming permanently attached to the complementary fastening surface when cured.
A multi-part curable mechanical fastener, comprising:
- a first part comprising a fastening surface;
- a second part comprising a complementary fastening surface that complements the fastening surface;
- wherein at least one of the first part comprising the fastening surface and the second part comprising the complementary fastening surface consists of a curable material comprising a combination of at least one thermosettable composition and at least one thermoplastic composition, such that when the fastening surface is mechanically attached to the complementary fastening surface, the multi-part curable mechanical fastener is capable of being cured to provide a permanent fastener.
