Abstract: A carrier-free expandable filler insert for filling or sealing a hollow space or cavity is provided. The insert comprises a self-supporting continuous structure that may be produced by contour extrusion molding or injection molding a polymer matrix containing a polymer and/or polymer precursor and a latent blowing agent. The expandable filler insert is secured to the interior surface of a vehicle pillar, for example, using a fixing element that may be integral with the self-supporting continuous structure, the polymer matrix thereafter being activated and expanded by heating.

Abstract: Multi-layer laminates are provided which contain at least two binder layers and at least two textile-containing layers. One binder layer faces a substrate to be reinforced, with a second binder layer between two textile-containing layers wherein one of the textile-containing layers is interposed between the binder layers. The binder layer facing the substrate has an elasticity modulus when cured which is less than or the same as the elasticity modulus of the second binder layer. The laminates are suitable for reinforcing or stiffening planar substrates, especially thin-walled substrates such as motor vehicle body parts.
