Adhesive bonding of steel structures may make them even stronger, according to a paper from Dow Automotive engineer Mansour Mirdamadi. Dow chemists have optimized the company's fracture toughened, one-component epoxy adhesives for use with AHSS. These highest-performing adhesives in this class typically have a modulus above 1,000 MPa and impact resistance across a wide temperature range (-40 to 80C). In his presentation, Mirdamadi describes a study that examined the role of structural adhesives in improving side-impact crash performance on a mini-van in IIHS tests. The results showed that an adhesive-bonded B-pillar structure offered a 5.4 mm intrusion improvement compared to a baseline design that uses no adhesive to supplement welding. In the same paper, he also lays out the significant contributions of fracture toughened adhesives to body stiffness and NVH.
