A tube reinforcement assembly is designed to reinforce complex tube structures, such as those having bends or varying inner diameters. The assembly includes a carrier and a plurality of spring-biased, deflecting wings around the carrier. The wings have structural foam layers 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 cured 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. |
