You cannot expect the members of PF to search for a new special spring material just because you hate steel.please find it friends
You probably mean... fibre-reinforced plastics ?to make leaf spring we can use any plastic materials ?
Dave McLellan said:We planned to use a massive front [roll] bar to achieve the roll stiffness we were after.
We found, however, that by spreading the body attachment of the front suspension fiberglass spring into two separate attachments 18 inches apart, we could achieve a major portion of the roll stiffness contribution of the front roll bar for free. We still used a massive front bar, but it would have been even bigger and heavier if it had not been supplemented by the leaf spring.
http://en.wikipedia.org/wiki/Corvette_leaf_springCarroll Smith said:If I were involved in the design of a new passenger vehicle, however, I would give serious consideration to the use of a transverse composite single leaf spring of unidirectional glass or carbon filament in an epoxy matrix. This would be the lightest practical spring configuration and, although space constraints would seem to limit its use in racing, it should be perfectly feasible on road-going vehicles, from large trucks to small commuter cars. (Since I wrote this paragraph the new-generation Corvette has come out with just such a spring to control its independent suspension systems-at both end of the car.)
Coil springs are better behaved than leaf springs because they do not need to be tapered or laminated.Not normally.
