Look for extensive use of ceramics and new woven polymer materials in the armored vehicle that will replace the US Army’s Humvee. The Joint Light Tactical Vehicle will come in three types that will haul cargo and perform reconnaissance missions. The target weight is 20,000 pounds, about half the weight of currently used armored vehicles. That’s only three to four times the weight of pickup trucks. Under consideration will be use of composite systems such as aramid-fiber reinforced materials (Kevlar), ultra-high molecular weight polyethylene (UHMWPE) composites, and S-2 glass armor systems, which are also used in the Boeing Dreamliner. Capacities of all three are being rapidly expanded in anticipation of higher demand for military and other types of applications. Manufacturers of all three materials are dramatically expanding capacity right now to meet soaring demand.
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.
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.
