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, they could keep its original shape perfectly in the kinds of badly
environments, 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 extensive used. Carbon f…
