Kevlar Composite

One of the most recognized uses of Kevlar is in body armor, such as bullet-proof vests. Kevlar, however, was first introduced in the 1970s and is now used in a wide range of products. The fiber itself has high tensile strength, making it very desirable for composite materials.

In fact, Kevlar was originally envisioned as a possible replacement for steel in rubber tires. As a reinforcement material, Kevlar has strength comparable to glass fibers. Its density, however, is much less and therefore Kevlar is often substituted in composite material when lower weight is a desirable physical property.

Grades of Kevlar Composite

There are three grades of Kevlar that are used in composite materials. While Kevlar 29 has similar strength to glass fiber at a lower weight, Kevlar 49 and Kevlar 149 can be used to reduce the weight even further. Why is Kevlar not used in all composite materials? The downside to using Kevlar fibers in composite materials is that it is more expensive than using other fibers such as glass.

If you are considering using a Kevlar composite but are uncertain if the trade off between lighter weight and increased price is worth the cost of construction, contact us at Concept Sales Inc. We can assist you in choosing not only the best composite material for your project, but also in locating a manufacturer who uses the most appropriate manufacturing process.
