1. Introduction to Multiaxial Carbon Fiber Fabrics
Multiaxial carbon fiber, also known as multidirectional carbon fabrics, is a composite material composed of extremely thin fibers predominantly made of carbon. These fibers are woven or stitched together in multiple directions to create a structure that exhibits strength and stiffness in various orientations. The multiaxial configuration allows for tailored reinforcement, providing enhanced performance compared to traditional unidirectional carbon fiber.
2. The Manufacturing Process of Multiaxial Carbon Fiber Fabrics
The manufacturing process of multiaxial carbon fiber involves several steps. First, carbon fibers are produced through the carbonization of organic precursors such as polyacrylonitrile (PAN) or pitch. These fibers are then combined to form a fabric by using techniques like weaving, stitching, or knitting. The fabric is further processed by impregnating it with a matrix material, typically epoxy resin, which acts as a binder and provides additional strength. Finally, the fabric is cured under controlled temperature and pressure to create the desired multiaxial carbon fiber structure.
