Carbon fiber (fibre) is extremely durable (modulus up to 700 GPa, the tensile strength up to 4000 MPa), the material of inorganic origin, which contains in its structure more than 80% carbon. Despite its strength carbon fiber is very light material, its share is only 1.7 g / cm3, which is almost 2 times lighter than the lightest aluminum metal, and almost 5 times less than steel. Outdoors material withstands overheating up to 400 C °, and in the absence of oxygen to 2500 ° C, so the carbon fiber used in the present time in the production of exclusive sports cars in the space developments in the aircraft industry.
In the production of glasses frames and Ray-Ban carbon fiber used in a very thin form-fitting temples consisting of seven layers, five layers of which consist of carbon fiber mixed with the resin, and watered for shaping. The result is a lightweight, durable, flexible and high-temples with rubber tips. In these same models are used MonobIock joints that are not soldered to the front of the rim, so are longer than conventional hinges. The lenses used for these frames, successfully passed the test "falling ball" when a ball with a diameter of 5/8 inch drops onto the lens from a height of 50 inches.
Carbon fiber is a very hygienic hypoallergenic material. Points to the rims of carbon fiber almost obscure, they have an anatomic shape and well follow the contours of the face. The consumer, after 15-20 minutes socks cease to notice them and takes points simply as a part of the body.
