    I need to make a simple "Z" spring and want to know what material would work best.
    I want the spring to compress about 1.5" at maximum load (400lbs) at room temp. The spring needs to be as light as possible. Would carbon fiber be too brittle? Any polymers out there as strong and light as carbon fiber but with more absorbing characteristics? Thanks.

    We tend to get paid for this. :p

    Let me send that to my friends, but I bet the advice is going to be Fe3C .

    no, nothing that complicated. Just toying with an idea I've had for years.

    u want to to go from 2" high unloaded to 0.5" with a 400# load?

    I think a foam material would work better then a Z shape with that much change in height. But foam likely won't be linear displacement vs load.

    I'm confused, are you looking for tensile strength i.e. carbon/kevlar or elasticity for tension/extension. two ends of the spectrum here. what you looking for will come down to the product usage, hard to make material suggestions in the dark on such a broad physics model.

    absorption?
    tension?
    extension?
    deformation acceptable?
    dampening rate?
    oscillation?
