Tensile Properties

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.

Table 1: Comparison of Properties of Various Engineering Materials
Material Density (g/cm3) Tensile Strength (G Pa) Specific Strength (km*) Tensile Modulus (G Pa) Specific Modulus (km**)

*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.
