Expandable thermosettable compositions containing at least one epoxy resin, at least one finely divided thermoplastic polymer powder, at least one blowing agent, at least one curing agent, and at least one filler are suitable for the production of thermosetting laminated bodies with a tacky surface. These laminated bodies can be produced and handled in a simple manner and are suitable for stiffening and reinforcing flat structural components, in particular vehicle body structural components, such as vehicle body frames, doors, trunk lids, engine hoods and/or roof components in automobile construction. The expandable thermosettable compositions are also suitable for the production of thermosetting, thermally expandable shaped articles for reinforcing hollow structural members by the injection molding process. In preferred embodiments, the composition is injected onto a metallic or thermoplastic carrier. These thermally expandable shaped articles are especially useful in the production of automobiles and other vehicles to maintain or increase the strength of structural members such as rockers, pillars, radiator support beams, doors, reinforcing beams, and the like.
