A composite future: Is plastic the key?

I was very excited to hear that Toyota was using carbon fiber composite materials to design its new FT-HS hybrid concept. More important, it appeared that Toyota wasn't just using composites to help with design - as many automakers do - but as a first step towards carbon-fiber composite vehicles. As carbon fiber is so light, it can provide significant improvements in fuel economy simply by reducing the weight of a vehicle without any loss in safety. Still, carbon fiber is very expensive.

Carbon fiber, however, isn't the only composite being used in automobiles.

A group of GE reps let me know about GE's plastic composites during the debut of GM's Volt electric concept vehicle. Currently, these plastic composites are far cheaper than carbon fiber composites. In addition to reducing weight, plastic composites provide car designers with a revolutionary tool to sculpt vehicle design into elegant, beautiful and extremely aerodynamic works of art and science. More important, plastic composites are already being used. Even better, GE's new plastic composites are being developed using recycled water bottles.
