An adhesive tape from 3M replaces the mechanical fasteners often used to build horse trailers, reducing the stress animals endure when they are transported.
VHB Tape provides enough strength to hold panels on horse trailers while also providing a bit of viscoelasticity to absorb vibrations. A recent study showed that horse trailers made with VHB Tape up to 41 percent quieter at highway speeds and vibration was reduced up to 30 percent over trailers made with mechanical fasteners. Veterinarians say that horses notice even 5 percent decreases in noise and vibration, according to 3M.
The tapes have been crash-tested at up to 60 mph, holding together during the tests. The tape is also used to attach roadside signs to poles, surviving 90 mph wind gusts. For more information, go to http://rbi.ims.ca/4933-506.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
