Composite Panel Joint Structure for Fastener-Free Load Transfer

The joint system divides the composite component into segments by introducing a split (gap) in the laminate structure. This segmentation allows insertion of triangular components that act as mechanical interlocks, enabling joining without compromising the integrity of the laminate layers. The split creates discrete zones for fastener insertion while maintaining overall structural continuity.

Triangular components serve as intermediary elements that bridge the gap between composite components. These intermediaries are inserted into the split and provide a mechanical coupling mechanism that transfers loads between composite parts without requiring direct penetration through the laminate thickness, thus avoiding local damage to the weak interlaminar regions.

The invention replaces the chemical bonding mechanism of adhesives with a mechanical interlocking system. Triangular components inserted into the split create physical engagement with the composite structure through friction and geometric interlock, providing a mechanically-based joint that is insensitive to adhesive degradation, aging, and environmental factors while maintaining consistent joint properties.

The triangular components and split structure create a self-locking mechanism where the geometry of the joint itself provides the joining function. The triangular shape engages with the split walls to provide mechanical interlock without requiring additional bonding agents or complex assembly procedures, making the joint self-sufficient and consistent.
