Abstract
Disclosed is an epoxy resin type composition for stiffening a vehicle body. The epoxy resin type composition comprises an epoxy resin, a powdery methacrylate type polymer in an amount of 2 to 45 parts by weight relative to 100 parts by weight of the epoxy resin, a thermally active hardening agent for epoxy resin in an amount of 1 to 20 parts by weight relative to 100 parts by weight of the epoxy resin, a thermally decomposable foaming agent in an amount of 0.5 to 20 parts by weight relative to 100 parts by weight of the epoxy resin, and a mixture of an inorganic salt with a shape of a predetermined aspect ratio and a granular inorganic salt in an amount of 50 to 200 parts by weight relative to 100 parts by weight of the epoxy resin. A mixing ratio of the granular inorganic salt is 0 to 50% by weight relative to the total amount of the mixture. Also disclosed is a method for stiffening a vehicle body by use of such a composition.
