Air bladders used in balls, helmets, footwear, and other sports equipment need to be tough and durable, and they must maintain their integrity despite being repeatedly kicked, hit, compressed, and flexed. In addition, such equipment must withstand environmental punishment, including temperature extremes and moisture. JPS Elastomerics Corp. feels it has such a material in Stevens Urethane. The thermoplastic urethane (TPU) gives these bladders the necessary tensile and burst strength, along with the elasticity and flexibility to "roll with the punches," says JPS' Sam Everett. Slim and sheet products come in thicknesses from 0.001- to 0.125-inch and widths up to 80 inches. Durometers range from 75 to 95 Shore A, with standard or custom colors and surface textures available. JPS Elastomerics Corp.: Product Code 4226
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
