ATTACHMENT OF COMPOSITE LUG TO COMPOSITE STRUCTURAL TUBE

摘要

The present disclosure describes lug clusters for composite tubes and methods for making such lug clusters. Lug clusters of the present disclosure may include a first side, a second side, and a saddle. The saddle may be placed in adjacent contact with a tube and a filament may be wound around the lug cluster and tube. The wound lug cluster and tube may be resin transfer molded. Machining may follow to remove material and finalize the shape of the lug cluster and/or tube. Thus, a lug cluster may be attached to a composite tube.

主权项

1. A lug cluster comprising:
a first side comprising a flange comprising a first side groove receiving a fiber filament according to a filament path; a second side comprising a flange comprising a second side groove receiving the fiber filament according to the filament path; and a saddle comprising:
a floor member comprising a planar member formed to follow a contour of a composite tube;an upper infill member resting on the floor member and positioned between the first side and the second side.
