What is Carbon Fiber? A Deep Dive into the Material’s Properties

Carbon fiber is a polymer composed of thin, strong crystalline filaments of carbon. These filaments are bonded together using a resin, forming a composite material that is incredibly strong and lightweight. The strength and stiffness of carbon fiber depend on several factors, including the type of carbon fiber used, the resin system, and the manufacturing process. It’s the arrangement of these fibers and the resin matrix that ultimately determine the material’s performance in various applications.

Think of it like wood. Different types of wood have different densities and strengths. Similarly, different grades of carbon fiber offer varying levels of performance. The way the carbon fibers are woven together also significantly impacts the material’s overall strength and resistance to impact.

Key Properties of Carbon Fiber
