Plastics have spring tension properties?

  1. Dec 24, 2007 #1
    I am developing a product and am going to integrate a piece of flat sheet spring steel into its design for the tension required to function as hoped. I wonder about the availability of plastics that have similar properties? Any thoughts.

    Merry Christmas eve day.

    In general, plastics are not elastic over a broad range of stress. However, some materials and designs do work. Do you have any specifications or sketches?

    We need more info. What is the design (roughly, at least)? What properties would you like the plastic to have - high yield strength, high strain at yield, large modulus, good fatigue strength...?
