An expansible reinforcer for reinforcing a hollow structural member of an automobile, aircraft, boat, etc. is provided. The reinforcer is flexible/bendable and comprises a synthetic, resin-based expansible reinforcing material secured thereto. In a preferred embodiment, the reinforcer comprises a plurality of supports pivotally connected to one another in a train-like arrangement. The reinforcing material is formed of a thermally expansible composition which preferably has an expansion temperature similar to the temperatures achieved in specific stages of a particular manufacturing process (e.g., such as the temperature at which the paint bake or powder bake stage is carried out in the automobile manufacturing process). The inventive reinforcer is capable of being fed into the opening of a tight cavity on a structural member so as to provide uniform reinforcement of the structural member. |
