The strength of both materials is similar. Kevlar® has a tensile strength of 3620 MPa and Dyneema® has 3600 MPa of tensile strength. But because Dyneema® has a much lighter density than Kevlar® (0.97 compared to 1.44), it scores a higher strength-to-weight ratio.

What material can stop a knife?

Kevlar® is a synthetic fibre with a very high tensile strength, making it ideal for body armour. Kevlar® was first introduced several decades ago and has since proven to be one of the strongest materials available worldwide. Kevlar® is used in both bulletproof and stab proof vests.
