Carbon composite is a lightweight and high-strength material, made from very thin strands of carbon that are tightly woven together to make a strong yet lightweight fabric. Carbon composite manufacturing is a tedious and technical process that requires special materials, equipment as well as precision, and expertise. Carbon composite manufacturing goes through a series of steps that are discussed below:
Production of Carbon Fiber – Carbon composite manufacturing starts with the creation of carbon fibers that are generally made from a carbon material called polyacrylonitrile (PAN). To align the molecular structure and remove non-carbon elements, the PAN fibers are heated and stretched in several stages. This further results in long strands of carbon fibers.
Weaving the Carbon Fiber – The next step in carbon composite manufacturing is weaving the carbon fibers into fabric-like sheets or the fibers are used as unidirectional layers, which depend on the desired strength and flexibility of the material. The weaving process provides structural stability to the material in multiple directions whereas unidirectional fibers provide strength in a single specific direction that is mostly required for a specific application.
Resin Infusion – After preparing the carbon fibers, these are mixed with a polymer usually epoxy resin. The infusion of fibers with a polymer is carried out either through the prepreg process, resin transfer moulding process, or through vacuum-assisted resin transfer moulding process. In the prepreg process, carbon fibers are pre-impregnated with resin and stored in a refrigerator until they are ready to keep in moulds for curing. In the RTM process, dry carbon fibers are placed in a mould, and resin is injected under pressure. This leads to precise control over the shape and consistency of the final product. The VARTM is an advanced process of RTM in which vacuum pressure is used to infuse resin through the carbon fiber layers. This further leads to uniform distribution and reduces voids within the composite structure.
Moulding – Carbon fibers infused with resin are carefully laid layer by layer in moulds to give the desired shape. The fiber orientation is vital because different arrangements will provide varying levels of strength and flexibility. To ensure the right balance of weight, strength, and stiffness in the carbon composite, skilled technicians design the layup pattern of the material that optimizes performance for specific applications.
Curing – The curing process is carried out after the layering and moulding of carbon fibers. In this process, a chemical reaction in the resin is initiated by exposing the composite to heat and pressure in an oven or autoclave that leads to harden the material and allows it to bond with the carbon fibers. It solidifies the structure and transforms carbon composite into a durable, rigid material that can withstand extreme conditions and heavy loads.
Finishing – The last and final step of carbon composite manufacturing is the finishing process in which the material undergoes trimming, sanding, and coating to obtain the desired dimensions and surface quality. Sometimes, additional treatments like painting or protective coatings may be required to enhance the aesthetics or to improve resistance to environmental factors such as UV radiation or corrosion.
With industries pushing the performance boundaries, the carbon composite market is expected to grow.
