Heat activated epoxy adhesive and its use in a structural foam insert

摘要

The present invention relates to a heat activated epoxy adhesive and its use in a foam insert that is bonded to a metal body. Structural foam inserts (SFIs) have been developed to reinforce structures within motor vehicles to add strength and stiffness to the vehicle at the site of insertion. Acoustical foam inserts (AFI) have been developed to reduce the impact of noise and vibration on vehicle Passages. For example, an SFI coated with an uncured expandable epoxy adhesive is secured to the B-pillar cavity of an automobile.
