Filament Wound Composite Tie Rod

摘要

A filament wound composite tie rod and method for fabricating the same includes end fittings coupled to a structural member tube and held by a filament-wound structure. The end fittings include lugs to guide and hold the filament at proper angles while holding the filament in place on the end fittings. The filament wound composite tie rod provides both higher tension and/or higher compressive load carrying capability than existing tie rods at a significantly reduced weight.

主权项

1. A filament wound composite tie rod comprising:
a structural member tube; a pair of end fittings, each end fitting having a cylindrical end feature and a cylindrical body, the cylindrical body having a plurality of lugs, a first of the end fittings attached to a first end of the structural member tube and a second of the end fittings attached to a second, distal end of the structural member tube; an open lattice body formed of interlacing filaments held in a solid matrix wound repeatedly around the end fittings and the structural member tube, along the structural member tube, the filaments being wound at an angle between 0 degrees and 90 degrees with respect to a longitudinal axis of the structural member tube, and the filaments wound around the cylindrical end feature of each of the end fittings at an arc of greater than 180 degrees.
