Composites today are used in innumerable applications because of their lightweight feature. Growing demand for efficient technical systems requires lightweight components that have become an integral part of product development. Thus, composites have revolutionised the manufacturing industry by offering materials of unparalleled strength, flexibility, and durability. Composite parts have become a significant part of diverse industries, from defence and construction to automotive and sporting goods. This material is preferred over traditional metals because of its lightweight properties and ability to withstand harsh weather conditions without affecting its performance.
Composite material is a material made from two or more distinct components. These components are combined to create a composite material having a better set of properties than the individual component alone. The common composite material constituents a reinforcing material like glass or carbon mixed in a matrix material like resin or plastic. The matrix material binds the fibers together and evenly distributes the applied force for overall durability. This further results in creating a composite material that is durable, stronger, lighter, and resistant to environmental factors like chemicals, heat, and wear and tear.
Some commonly used composite materials include:
Carbon Fiber Reinforced Polymer (CFRP) – Used majorly in automotive, aerospace, and sports goods industries, this composite material is known for its durability and high strength-to-weight ratio.
Glass Fiber Reinforced Polymer (GFRP) – This composite material is preferred in construction and marine applications because of its affordable price, durable quality, and corrosion resistance.
Kevlar – It is a high-strength composite material that is light in weight and resistant to heat. This material is widely used in protective clothing and equipment like body armour and helmets.
There are several manufacturing processes for fabricating composite parts. The selection of a manufacturing process for making composite parts generally depends on the composite material, and the end-use or application. Some of the commonly used composite part manufacturing processes include:
Hand Lay-Up – This is one of the simplest and highly traditional methods employed in the manufacturing of composite parts. In this process, reinforcing fibers like glass or carbon are manually placed into a mould, and then resin is applied. The resin used in this process is cured either at room temperature or under heat and pressure to harden it. The hand lay-up process is preferred for manufacturing large, low-volume parts like wind turbine blades or boat hulls.
Filament Winding – To cater to the requirement of manufacturing cylindrical composite parts like tanks, pipes, and pressure vessels, the filament winding manufacturing process is used. In this, continuous fiber strands are wrapped in a precise manner around a rotating mandrel and are later impregnated with resin. The mandrel is removed after the curing process which leaves a highly strong and lightweight composite material.
Resin Transfer Molding – It is a highly automated process in which dry fibers are placed into a closed mould and then resin is injected under pressure. The fibers are impregnated by the resin and later on, the part is cured in the mould. This manufacturing process produces high-quality composite parts having excellent surface finishes. This manufacturing process is employed to manufacture composite parts that are used in aerospace and automotive industries where precision and consistency are crucial.
Autoclave Molding – This manufacturing process is adopted to produce high-performance composite parts that are usually required in the aerospace industry. Under this manufacturing process, resin-impregnated fiber layers are laid into a mould that is vacuum-bagged and placed in an autoclave. The composite part is then subjected to high heat and pressure to compact the material and to ensure uniform curing. This manufacturing process produces composite parts that have excellent durability and strength.
Pultrusion – Long and straight composite parts like beams, rods, and channels are usually made through the pultrusion manufacturing process. This manufacturing process involves pulling fibers first through a resin bath and then through a heated die to give shapes and cures the material. It is preferred to manufacture composite parts that are used in infrastructure, construction, and energy applications.
Some of the prominent benefits of composite materials include:
Lightweight – Composite materials are lightweight compared to other metals like steel and aluminium. Thus, composite material is preferred in industries like automotive and aerospace where light weight leads to better fuel efficiency.
High Strength and Durability – The exceptional strength of the composite materials along with their ability to withstand harsh environmental conditions make them ideal to be used across marine, oil and gas, and industrial sectors, where materials are required to endure challenging conditions.
Design Flexibility – Composite materials provide manufacturers with great flexibility to create parts with complex shapes, sizes, and geometries that are hard to achieve using conventional methods. This feature makes composite materials valuable for aerospace and architecture industries that require parts with intricate and customized designs.
With the ongoing research and development in this sector, the future of composite parts manufacturing looks promising.

Carbon composites are materials made of carbon fibers embedded in a polymer matrix usually epoxy resin. It is also referred to as carbon fiber-reinforced polymers (CFRP) in which carbon fibers offer strength and stiffness whereas polymer matrix distribute the load and prevent fibers from getting damaged. The amalgamation of carbon fibers and polymer matrix creates a material that is extremely strong yet light in weight. The best thing about carbon composites is that it exceeds the strength-to-weight ratio of metals like steel and aluminium. Due to a fine blend of properties, this material proves ideal for industries like aerospace and automotive where light in weight and high-performance vehicles are highly valued. Vehicles that are light in weight have better speed and fuel efficiency, thus carbon composites are of great value to these industries.
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. Several studies and research have been going on into new composite materials like hybrid composites that is a combination of carbon fibers and materials like glass to enhance properties like toughness or cost-effectiveness. Research is also being carried out to come out with a sustainable carbon composite manufacturing process that reduces energy consumption during production and comes out with ways to recycle carbon composites after their life cycle. These are crucial to make this material more eco-friendly.
