Have any ideas on how to improve materials engineering for golf carts? They’re a great candidate for a new approach because of skyrocketing accidents. Half of golf cart injuries occur on streets or residential property, and there was a surge in golf cart use when gas prices soared last year. One retiree bought a 20-year-old cart for $300 that can go 20 miles on a 10-hour charge. Twenty-six states allow use of golf carts on local streets. Some states require hazard signs on the back, not unlike the bright signs on the back of Amish buggies. A study by the University of Alabama at Birmingham, said about 1,000 Americans suffer injuries monthly due to golf cart accidents. Male teenagers and people over 80 had the highest injury rates. A study by the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus, OH, said annual injury rates for golf carts increased 130 percent in a recent 16-year period.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
