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.
A few weeks ago, Ford Motor Co. quietly announced that it was rolling out a new wrinkle to the powerful safety feature called stability control, adding even more lifesaving potential to a technology that has already been very successful.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
