Engineered elastomer. (Literature: materials).Brochures and technical bulletins describe various aspects of Kevlar engineered elastomers. Kevlar para-aramid fiber was originally introduced in filament filament, in astronomy: see chromosphere. yarn form to reinforce a variety of high performance articles, including tires, composites, mechanical rubber goods, protective apparel and fiber optics fiber optics, transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber cables. Kevlar is said to be five times stronger than steel on a same weight basis. Kevlar is characterized by high tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its , high modulus or stiffness, flame resistance, excellent thermal resistance, excellent chemical resistance and low thermal conductivity, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the literature. (DuPont Advanced Fi-bers Systems, P.O.
