What is claimed is: 1. 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. 2. The curable mechanical fastener of claim 1, wherein the curable mechanical fastener is reclosable for at least one hour after fabrication. 3. The curable mechanical fastener of claim 1, wherein the curable mechanical fastener is reclosable for at least one month after fabrication. 4. The curable mechanical fastener of claim 1, wherein the thermosettable composition comprises at least one thermosettable material selected from the group consisting of (meth)acrylates, urethanes, ethers, epoxies, cyanates, esters, phenolics, polyimides, amine formaldehyde condensates, and mixtures thereof. 5. The curable mechanical fastener of claim 1, wherein the thermosettable composition comprises an epoxy. 6. The curable mechanical fastener of claim 1, wherein the thermoplastic composition comprises at least one thermoplastic material selected from the group consisting of polyesters, polyolefins, polyamides, polyethers, polyurethanes, plasticized polyvinyl chloride, thermoplastic elastomer block copolymers, phenoxy resins, polyketones, silicones, polyetherimides, polycarbonates, polysulfones, polyoxides, and mixtures thereof. 7. The curable mechanical fastener of claim 1, wherein the thermoplastic composition comprises a polyester. 8. The curable mechanical fastener of claim 7, wherein the polyester is semi-crystalline at room temperature. 9. The curable mechanical fastener of claim 1, wherein the thermosettable composition comprises an epoxy and the thermoplastic composition comprises a polyester. 10. The curable mechanical fastener of claim 1, wherein the curable mechanical fastener is a hook-and-loop mechanical fastener. 11. The curable mechanical fastener of claim 1, wherein the fastening surface comprises protruding fastening elements and the complementary fastening surface comprises recessed structures. 12. The curable mechanical fastener of claim 1, wherein the fastener is formed by a method selected from the group consisting of extruding, melt-blowing, molding, and microreplicating. 13. A mechanical fastener according to claim 1 which has been cured. 14. The cured mechanical fastener according to claim 13, wherein the curable mechanical fastener is cured using actinic radiation. 15. The cured mechanical fastener according to claim 13, wherein the cured mechanical fastener has an overlap shear strength of at least about 7 MPa. 16. A method of forming a permanent fastener comprising the steps of: providing a curable mechanical fastener according to claim 1; attaching the fastening surface to the complementary fastening surface; and curing the mechanical fastener to provide a permanent fastener. 17. The method of claim 16, further comprising the step of attaching the curable mechanical fastener to a substrate. 18. The method of claim 17, wherein the curable mechanical fastener is permanently attached to the substrate. 19. The method of claim 16, wherein the complementary fastening surface is part of a curable mechanical fastener, the method further comprising the step of permanently attaching the curable mechanical fastener comprising the complementary fastening surface to a substrate. 20. 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. 21. The curable mechanical fastener of claim 20, wherein at least one fastening element is mushroom-shaped. 22. 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. 23. The curable mechanical fastener of claim 22, wherein both the fastening surface and the complementary fastening surface comprises a curable material. 24. The curable mechanical fastener of claim 23, wherein the curable material of either the fastening surface or the complementary surface comprises a functionalized-thermoplastic composition.
