Design Tensile & Modulus Properties
Tensile and Modulus Properties are measured per ASTM
D7205-06, Standard Test Method for Tensile Properties of
Fiber Reinforced Polymer Matrix Composite Bars. The
ultimate tensile load is measured and the tensile modulus is
measured at approximately 10% to 50% of the ultimate load.
The slope of the stress-strain curve is determined as the
tensile modulus. Ultimate Strain is extrapolated from the
ultimate load divided by the nominal area and modulus. The
area used in calculating the tensile strength is the nominal
cross sectional area.
