Abstract
Methods and fasteners are provided for joining thermoplastic articles and for connecting a single thermoplastic article to a non-thermoplastic substrate. A first thermoplastic article and a second thermoplastic article can be placed against each other, and then localized adjacent portions of the articles are heated preferably with an ultrasonic heating device. A sharpened end of a thermoplastic fastener is driven through the heated areas of the first thermoplastic article and the second thermoplastic article. Upon cooling of the heated areas of the first thermoplastic article and the second thermoplastic article, those articles are looked to the thermoplastic fastener by fusion of the contacting surfaces of the articles and fastener.
