Composite materials require specialized techniques for bonding and joining due to their unique properties. Adhesives, such as high-strength epoxies or acrylics, are often used to bond dissimilar materials and distribute stress evenly. Mechanical fasteners like bolts and rivets must be carefully selected to avoid damaging the composite structure, with isolation materials preventing galvanic corrosion. Advanced methods like co-curing and z-pinning enhance bonding and through-thickness strength. The choice between adhesives and fasteners depends on load requirements, environmental conditions, and disassembly needs.
