Chopped carbon fiber consists of short lengths of carbon fiber strands, offering strength and lightweight properties. It is used as a reinforcement additive in materials like plastics and resins, enhancing strength and stiffness. By blending it with a matrix material, chopped carbon fiber improves the mechanical properties of the resulting composite, making it ideal for industries like aerospace and automotive.
Carbon fiber has a tensile strength of about 2,500-6,000 MPa, making it one of the strongest fibers, particularly when aligned in the same direction.
Carbon fiber retains its properties up to about 2,500° C in non-oxidizing environments, far surpassing many other fibers in terms of thermal stability.
The density of carbon fiber is around 1.5-2.0 g/cm³, significantly lighter than steel (7.85 g/cm³), contributing to its high strength-to-weight ratio.
Carbon fibers exhibit high modulus, i.e., stiffness, typically 200-700 GPa, which means they deform very little under load, ideal for aerospace, sports equipment, and automotive industries.
