Reinforcement materials such as continuous carbon fiber are used to increase the stiffness and strength of structures or parts. The concept of using continuous carbon fiber for reinforcement is based on its special qualities. Even when compared to metals, its tensile strength is extremely strong, enabling the creation of parts with anisotropy and manipulation of it in the necessary directions inside the structure of a printed part. Keep reading as we explore the basics of continuous carbon fiber, its properties, and its diverse applications, focusing on carbon fiber products; carbon fiber fabric and carbon fiber sheets.

What is Continuous Carbon Fiber?

Continuous carbon fiber is composed of long, continuous strands of carbon atoms bonded together in a crystal alignment. This alignment provides the fibers with exceptional strength and stiffness. Continuous carbon fiber is made by drawing long, thin strands of carbon fibers into a continuous yarn and then woven into carbon fiber fabric, which can be used directly or processed into various carbon fiber products. Continuous carbon fiber differs from chopped or short fibers in that it offers superior mechanical properties due to the uninterrupted nature of the fibers. This material offers a high strength-to-weight ratio, making it stronger and lighter than steel or aluminium. Continuous carbon fiber is ideal for applications where strength and weight are critical like in aerospace, automotive, and sporting goods.

Properties of Continuous Carbon Fiber

Continuous carbon fiber is a highly sought-after material in many industries due to its many important features. Continuous carbon fiber is primarily appealing due to its exceptional strength-to-weight ratio. It has equivalent, if not greater, strength to metals like steel and aluminium yet is much lighter. This feature is especially helpful in sectors like aircraft, automobile, and sports equipment manufacturing where reducing weight is essential. Because continuous carbon fiber has a high fatigue resistance and can bear repeated stresses without breaking, it is a good material for structural components that are subjected to cyclic loadings. Furthermore, carbon fiber has a high level of corrosion resistance, which makes it perfect for abrasive situations. Under temperature variations, its low thermal expansion coefficient guarantees dimensional stability. Usually, continuous carbon fiber is utilized to create composite materials, where the fibers are immersed in a matrix of binding agents or resin. This results in a material that is resilient to impact, flexible, robust and stiff.
