Properties and application of Kelvar and its composites

Abstract

In recent years, synthetic fiber reinforced composites have attracted more and more attention. The advantages of these materials compared to other traditional metal materials are reflected in their lighter weight, more unique flexibility, and superior mechanical properties. Because of this, these synthetic fiber composites are increasingly used in industry, the military, and other advanced technologies. Among them, Kevlar fiber composites have unique properties. Compared with other synthetic fibers, it has lower fiber elongation and higher tensile strength and modulus. Not only that, but the Kevlar composite also has better thermal properties and impact resistance. This article will first introduce the properties of Kevlar fiber, and then introduce different kinds of Kevlar composite materials. These include MS-Kevlar, SSG@Kevlar, Kevlar-Reinforced composites, and Kevlar aerogels. Because these composites have many different properties, they can have corresponding products in many different fields. The knowledge of existing materials helps us think about more applications for these new composites.
