Vectran® offers a distinct advantage over traditional metals in terms of strength-to-weight ratios.This is demonstrated in Table 1,which lists the tensile properties and densities of various reinforcing materials. Table 2 gives the mechanical properties of Vectran® yarn. Even higher tensile strengths are characteristically associated with lower deniers.

*Specific strength = Strength/Density (also divided by force of gravity for SI units). Also known as breaking length, the length of fiber that could be held in a vertical direction without breaking. ** Specific modulus = Modulus/Density (also divided by force of gravity for SI units). This measure increases with increasing stiffness and decreasing density. (KAI data) |
