NOTE: This is not Kevlar ® 29, which is built for ballistic applications. The density of Kevlar ® 49 is 1.44 g/cm 3 or 0.052 lb/in 3. For comparison, carbon fiber has a density of 1.76 g/cm 3 or 0.064 lbs/in 3 respectively. Kevlar is less dense than carbon fiber and far less stiff. Tensile modulus is ~16msi vs. 33msi for standard modulus carbon.
