TOUGHENED EXPANDABLE EPOXY RESINS FOR STIFFENING AND ENERGY DISSIPATION IN AUTOMOTIVE CAVITIES

摘要

toughened structural adhesive foam is to generate a gangseonghwa material for vehicle panels and the body shell structure. The Toughening structural adhesives containing an epoxy resin, rubber, elastomeric robust agent, a curing agent and a blowing agent. The adhesive foam structure greatly increases the amount of energy that the body panel or shell structure during the impact absorption. The combination of blowing agent and the chemical foaming agent is in particular expandable microballoons provide a good energy absorption. ;
