This document is a technical material on para-aramid fiber "Kevlar," which has characteristics such as high strength, high elasticity, and cut resistance. Aramid fiber Kevlar® has continuously created new applications and functions in response to the needs of the times, competing and coexisting with other super fibers. Historically, it has been used as a friction material to replace asbestos, as a tension member for optical fibers during the IT revolution, and as seismic reinforcement sheets to protect buildings from successive earthquakes. In recent years, "Kevlar® fabric for roof reinforcement" has gained attention in volcanic Japan as a technology and material that protects human lives. As the demand for advanced safety measures against natural disasters increases, and with the infrastructure development for the 2020 Tokyo Olympics and Paralympics progressing in airports, railways, and roads, we at Kevlar® will contribute to society through the creation of new high-performance products in collaboration with our customers.
