Patent number: 5338611Abstract: Microwave frequencies in the range of 0.5 GHz to 10 GHz are used to weld thermoplastic substrates by interposing a carrier strip. The strip is formed of a polymer carrier which is miscible in the substrates. Electrically conductive submicron carbon black susceptor particles are chosen with specified properties such that they generate enough heat within a specified time to produce a weld in which the heat generated is confined to the weld zone. The resulting weld is such that the welded assembly has essentially the same dimensions as the clamped assembly. Glass fiber reinforced substrates are welded without breaking glass fibers in the weld zone. Lap strength of welded substrates is greater than that of substrates joined by prior art methods, whether by welding or adhesive bonding. Articles microwave welded in accordance with the invention are useful for manufacturing and repairing vehicle components such as automobile bumpers and dashboards and other structural parts of automobiles, aircraft, and spacecraft.Type: GrantFiled: February 20, 1990Date of Patent: August 16, 1994Assignee: Aluminum Company of AmericaInventors: Herbert J.
