<p>A tube reinforcement assembly (100) is designed to reinforce complex tube structures, such as those having bends or varying inner diameters. The assembly includes a carrier (102) and a plurality of spring-biased, deflecting wings (104) around the carrier. The wings have structural foam layers (106, 108) on both surfaces that expand when heated. In one application, the wings of the assembly are compressed so that the assembly can fit around bends and narrow areas within the tube. Once the assembly is in its desired position, the structural foam is expanded and cure so that one expanded foam layer presses against the inner wall of the tube structure and the other expanded foam layer presses against the carrier of the reinforcement assembly.</p> |
