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.
Unlike industrial robots, which suffered a slight overall slump in 2012, service robots continue to be increasingly in demand. The majority are used for defense, such as unmanned aerial vehicles (UAVs); and agriculture, such as milking robots.
