In the field of material science, advanced composites have emerged as high-potential materials that stand out as transformative forces. Made from two or more constituent materials having different physical or chemical properties, the composite material has characteristics different from the individual components. Due to new and unique mechanical and physical properties, advanced composite materials are replacing conventional materials in diverse fields of applications like automotive, aeronautical, aerospace, and biomedical.
Advanced composites comprising of a matrix like a polymer, metal, or ceramic are reinforced with fibers like carbon, glass, or aramid and have revolutionized industries ranging from aerospace and automotive to sports equipment and renewable energy. The crux of advanced composites lies in their ability to blend the best properties of their constituents. For instance, carbon fiber-reinforced polymers (CFRP) offer a remarkable blend of high strength-to-weight ratio, stiffness, and corrosion resistance. This makes them ideal for applications where weight reduction is crucial without compromising structural integrity.
Advanced composites, also known as polymer composites, are created by merging a reinforcement material such as fiberglass, carbon fiber, or aramid fiber with a resin, which is essentially a type of polymer. This combination harnesses the strength of the fiber and the distinctive advantages of the polymer, such as fire resistance or chemical resistance. The manufacturing of polymer composites offers numerous methods, tailored to the desired properties, shape, and volume of the application. The manufacturing process of advanced composites is intricate and demands precision. The most common methods include:
Lay-Up Process – This involves manually placing layers of composite fibers in a mold, followed by pouring thermoset resin over the fiber layer. Pressure is applied using a hand roller to compact the fiber layer and impregnate it with thermoset resin. It’s a labour-intensive process but allows for high customization and is widely used in producing large structures like boat hulls and wind turbine blades. This method is widely used in the marine industry because of its low cost and simplicity.
Filament Winding – Filament winding is a technique mainly used to produce hollow, circular, or prismatic components like pipes and tanks. This process involves winding continuous fiber tows onto a rotating mandrel with a specialized winding machine. Filament-wound parts are widely used in the aerospace, energy, and consumer product industries. In this process, fibers are wound around a rotating mandrel in specific patterns and then impregnated with resin. This technique is excellent for creating high-strength cylindrical structures like pipes and pressure vessels.
Pultrusion – It is an automated manufacturing process in which continuous lengths of fibers are pulled through a resin bath and then through a heated die to form a constant cross-section profile. In this process reinforced fibers, pigments, and liquid pultrusion resins are pulled through a heated die, converting into composite materials. It’s highly efficient for producing uniform, high-strength composite materials like beams and rods.
Resin Transfer Molding (RTM) – In this process, fibers are cut into desired sizes and then placed in the lower half of a mold. The fiber is compacted until the desired thickness is achieved and then enclosed with a rigid upper mold. The resin is injected into the mold with injection pressure, filling the voids and creating a solid composite structure. RTM offers high dimensional accuracy and surface finish, making it suitable for complex shapes. This process is used to manufacture composite parts that have high mechanical properties and excellent surface quality.
Recent advancements in composite manufacturing have focused on improving efficiency, reducing costs, and enhancing material properties. Some notable innovations include:
Automated Fiber Placement (AFP) and Automated Tape Laying (ATL) – These technologies automate the placement of composite fibers, significantly increasing production speed and accuracy while reducing labor costs.
