+-45 degree carbon fiber fabric Carbon fiber multi-axial cloth is a kind of non-crimp, multi-axial and multi - structure reinforcing material. Each layer is sewn together with a polyester yarn. By using multiple directions (0 °, 90 °, + 45 °, 45 ° -) of the different combination, can also add chopped layer or stitch-bonded mat and other material. Carbon fibers or carbon fibres are fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when compared with…
