Bayer Polymers LLC (www.bayer.com/polymers-usa) has come out with a new materials system that helps manufacturers get back to nature. Called Baypreg F, it features a polyurethane chemistry optimized for use with natural fiber reinforcing mats and a related processing technology from
Bayer's Hennecke Machinery Unit. Parts made from the system—which can be found in Audi, BMW, and Mercedes-Benz interiors—typically use a natural fiber mat made from flax and sisal. Hemp mats are another possibility. Bayer has also used the technology to create sandwich-panel composites-in which natural fiber mat and polyurethane surround a honeycomb core made from paper or aluminum.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicle’s parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but that’s just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
