Kevlar flexibility

  1. Dec 11, 2005 #1

    I know this is my 3rd topic on kevlar but they arent the same question so :P

    Anyway, DuPont (the company who own the Kevlar brand) claim that it is flexible, yet it is a cristaline ploymer which makes it stiff, so how can it be flexible as well?

    Depends on how 'flexible' and 'stiff' are defined. Stiff as in, high modulus? Flexible as in large yield strain? I'd also like to note that often, marketing distorts science/engineering for a broader public appeal as well (whether its sensible or not).
