Processes in composites manufacturing encompass a diverse array of techniques employed to fabricate composite materials. These processes include methods like hand layup, where layers of resin and reinforcement materials are manually placed, and vacuum infusion, where a vacuum draws resin into a preform. Other techniques like compression molding, filament winding, and automated methods such as 3D printing are utilized to create intricate and specialized composite structures. Each process offers unique advantages in terms of precision, scalability, and efficiency, catering to diverse industry needs. As technology advances, newer methods are emerging, promising faster production cycles, reduced waste, and increased customization, driving the evolution of composite manufacturing towards more sophisticated and versatile methodologies.

Bonding and welding play vital roles in the assembly and fabrication of composite materials, offering methods to join components together effectively. Bonding involves the use of adhesives or bonding agents to create strong connections between different composite parts or between composites and other materials. Adhesives provide uniform stress distribution, enabling lightweight and durable structures. On the other hand, welding techniques like ultrasonic welding or induction welding are employed specifically in thermoplastic composites, where heat is used to melt and fuse the materials together.
