Abstract
A reinforcing member for a structural component such as a rail or channel of a vehicle is provided which includes a carrier and a thermally expansible structural reinforcing material element which is fastened to the carrier by mechanical fixation or an adhesive. The mechanical fixation may be provided by a flange or other mechanical connection on the carrier or by a fastener such as a push pin extending through aligned holes and openings in the carrier and foamable material. The push pins are preferably of a synthetic resin material which more closely approximates the heat conductivity of the foamable material when the latter is activated by heat, and is sufficiently yieldable to absorb impacts to the foamable material during installation.
