<p>The epoxy resin type composition comprises: an epoxy resin, 100 parts (by weight); a powdery methacrylate type polymer, 2 to 45 parts; a thermally active hardening agent, 1 to 20 parts; a thermally decomposable foaming agent, 0.5 to 20 parts; and a mixture containing an inorganic salt, with a predetermined aspect ratio, and a granular inorganic salt, the mixture amounting to 50 to 200 parts. The 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.</p> |
