Paragraph starter

The selection of assembly methods for hybrid metal-composite structures is critical for ensuring optimal performance and longevity. Conventional methods such as bolted joints can compromise the structural integrity of composite materials through fiber disruption and delamination. Research indicates that advanced mechanical joining techniques, such as self-piercing riveting, offer a viable alternative by minimizing direct fiber damage, thereby enhancing joint durability and resistance to failure. This approach is particularly relevant when designing for demanding applications where lightweighting and high strength are paramount.
