Composite fabrication involves combining two or more distinct materials to create a stronger, lightweight, and durable structure. Common methods include hand lay-up, vacuum bagging, resin infusion, and autoclave curing. The process typically uses reinforcement materials like carbon fiber, fiberglass, or Kevlar with a polymer matrix such as epoxy or polyester resin. Composite fabrication is widely used in aerospace, automotive, marine, and sports industries for high-performance applications.
