Composite parts are manufactured using advanced techniques to ensure that fibers are precisely layered and oriented to offer the desired mechanical properties. Some of the key methods employed to manufacture composite parts include:
To manufacture composite parts through autoclave moulding, pre-impregnated fiber sheets are placed in a mould inside an autoclave and subjected to high pressure and temperature. Parts made with this process have high strength and are of top quality. This process is expensive and time-consuming and hence is used for making parts for high-end applications like aerospace.
This process is generally used to manufacture large and complex parts that are mostly required in the automotive industry. In this process, fibers are kept in a mould, and resin is injected to saturate the fibers. This process is used to create strong and large parts having a high glass-to-resin ratio and is generally used to make car body shells.
Pultrusion is a composite parts manufacturing process that turns resin matrices and fiber reinforcements into straight, long parts having different cross-sectional shapes like hollow tubes, flat and corrugated sheets, channels, and angles. This is an automated process in which fibers are pulled through resin and a heated die to produce long, continuous parts with consistent cross-sections. This process is ideal for parts like beams, and rods, and for other construction structures.
Additive manufacturing or 3D printing is increasingly used for manufacturing composite parts of complex shapes. The parts manufactured through this process result in minimal waste. Though 3D printing is in its early stages for manufacturing composite parts but shows promise for rapid prototyping and customized parts.
Composite parts find great application across aerospace and defense industries where weight, fuel efficiency, and performance greatly matter.
