What is carbon fiber used for?
The most widely used form of carbon fiber, called intermediate modulus (or IM) carbon fiber will break at a load around 300,000 lbs per square inch of material along the fiber direction in tension. When the carbon fiber is woven into cloth, the tensile strength drops roughly in half as half the fibers are strong in one direction and half are strong in the other direction.
Carbon fiber has very high tensile strength due to the carbon fibers encased in epoxy. If you pulled a piece of carbon fiber it will withstand a high degree of force before failure. At the same time carbon fiber is succeptable to facture caused by impact. That is the reason many comsumer goods have a backing material in addition to the carbon fiber. This helps strengthen the carbon fiber in the "fracture department". http://www.carbonfiberdesigns.com has…
