A braided, open structure composite made with large prepreg tow can be cured without bonding at the yarn crossovers and after removal from the mandrel, it can be used directly as a spring in which the spring constant in bending, torsion, tension or compression can be controlled by the geometry of the braided structure as well as the size of the structural elements. Alternatively the spring may be curved in multiple directions to form complex shapes and then crossovers can be re-bonded to make more rigid open structure composites that would be difficult or impractical to manufacture by conventional techniques.

Composite braided open structure without inter-yarn bonding, and structures made therefrom

Preforms for open structured (lattice) composite tubular members manufactured from large (i.e. high filament count) prepreg yarns on a conventional maypole braiding machine, and subsequently cured to produce fiber reinforced composites of high strength and light weight.

Minimal weight composites using open structure

A composite prepreg yarn designed and constructed is a very large, strong yarn with resin infused throughout, which can be used to prepare composite preforms via conventional Maypole braiding or other textile processes. The invention increases the loads that can be transmitted by the cured yarn in a composite structure, decreases the stickiness that can prevent their use in braiding and other textile processes, provides protection to the high-strength fibers from abrasion that is encountered during and after composite preform manufacturing via braiding.

Robust pre-impregnated yarn for manufacturing textile composites

An electro-optical-mechanical tether to transmit both optical signals and electricity to and from airborne and other movable devices from a base structure, in which the tether includes a mechanical strengthening core covered by a first intermediate compressive layer which is helically wrapped by a plurality of electrical and fiber optic conductors, which constitute an second intermediate layer of the tether, and a outer protective layer.

High strength tether for transmitting power and communications signals

A braided eye splice is presented that is formed with the braider yarns of the rope, in which the braider yarns are braided back into the rope. A braided section of rope may be used as a braider yarn or combined with another braider yarn to form the splice. The tensile failure of ropes made with this splice occurs outside the spliced section, suggesting that full rope strength is maintained.
