Carbon Fiber is composed of carbon atoms which are organized to form a crystalline structure. It has great stiffness and strength. It is also superior to other reinforcing fibers when it comes to strength-to-weight ratio.
Carbon fiber is superior to Onyx when it comes stiffness and strength. Of all reinforcing fibers, Carbon Fiber has the highest strength-to-weight ratio.
Since carbon fibers are reinforcing-filament, they are rarely used on their own.
Applications of FDM
Carbon fiber is typically used to reinforce parts that replace machined aluminum. It is widely used in industries such as automotive and aerospace, but it is also used in sporting goods, civil engineering, and electronic fields.
Did you know?
In 1958, carbon fiber was invented near Cleveland, Ohio. But it still took around five years (1963) before its potential stregth was finally realized. PC is also used to replace metal parts. This reduces the weight, therefore reducing the fuel consumption of automobile, aircraft, or other vehicle. The Airbus A350 is a great example for this. It has 52% carbon fiber-reinforced polymer (CFRP). Anther one is the BMW i3 which has mostly CFRP chassis.
