Introduction of carbon fiber as material in eyeframes
Carbon fiber is a kind of new materials of eyeframes , It has not only the inherent characteristics of carbon, but also has the soft and machinable of textile fibers. The carbon fiber is as the material for producing eyeframes and sunglasses, and these eyeframes has the soft and machinable of textile fiber. And carbon fiber is very resisting corrosion . After tested the carbon fiber eyeframes , t hey could keep its original shape perfect ly in the kinds of badly environment s, the feature is not available in metal also titanium eyeframes . Carbon fiber is a new material with excellent performance, and its weight is less than 1/4 of steel, its tensile strength is generally above 3500Mpa, and it is 7-9 times of steel.Therefore, the ratio of its strength and density can be up to 2000Mpa/(g/cm3), and the ratio of A3 steel is only about 59Mpa/(g/cm3). Many people expect that the application of materials will be from the steel age to the composite materials age which will be ext
