Bonding of Composites
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.
