Archie, I think the fascination with carbon fibers is the environmental factor. However, the steel folks argue that the front end of the carbon fiber process eats up considerable energy -- plus, they argue that steel is very easy to recycle.

The strength to weight ratio of carbon fiber composites is higher than that of glass fiber composites. And the greater stiffness is very important in cars and planes.

Ann, does that mean that glass fiber composites are likely to get sidelined? Or, are there still applications for which glass fiber composites are the superior solution?

Not at all, Rob. Many composite developers we've reported on are working on both types. They each can have their place in a given vehicle.

I read with interest the threads on CF –I am involved with many companies worldwide regards CF composites and what I am seeing is new CF material formats combined with new and modified process and polymers that are opening up a significant potential for auto applications. Aluminium's, steels, titanium and magnesium will never compete with a material format that can be moulded with variable thicknesses – strategic laminate direction and can be combined with many other materials. You will see a greater use of glass CF hybrids in the future. Regarding recycling – with the greater acceptance of TP polymers and their increase performance the recycling issue goes away!! so yes the use of CF is inevitable !!

I sure wouldn't want to be anywhere close to a car fire if there was any significant amount of flamable metal in it's ocnstruction.
