Composite Control Cables and Stabilizing Tendons for Aircraft Applications and Method for Manufacture of Same

Номер: US20220056640A1
Автор: Jeremiah Schwartz, Rob Sjostedt
Принадлежит: Galactic Co LLC

Control and stabilizing cables and tendons for high altitude aircraft and airships having lightweight, high strength and low CTE are disclosed, along with a method and machine for fabrication of same. The cable is comprised of a fiber prepreg tow encased in a polymer sleeve with one bobbin at each end to facilitate connections. Consolidating the fiber prepreg tow along the length of the cable using high temperature shrink tubing, such as polyvinylidene fluoride (PVDF), allows for eliminating the twisting of the fiber prepreg tow, thus reducing the number of wraps around the bobbins. Eliminating the twists in the fiber prepreg tow also reduces the length of fiber needed, and therefore the overall change in length of the control cable with temperature variations is reduced. Additional cable strength can be achieved by adding and holding significant tension on the fiber prepreg tow by applying weight during the curing process.

Methods, a consumable assembly, and a tool for preparing a composite structure from a laminate disposed on a surface of a mold. The method involves preparing consumable materials, such as a breather sheet and a vacuum bag, and preparing an inflatable tool, outside of the mold. These prepared consumable materials and the inflatable tool are then inserted into the mold, and the inflatable tool is inserted into a folded assembly of the breather and vacuum bag. Once inserted into the mold, the inflatable tool is inflated, which deploys the consumable materials against the laminate. A vacuum can be generated, which maintains the deployed consumable materials against the laminate. This can be done for many hours. Finally, the laminate is cured inside the mold so as to form the composite structure.

The invention relates to a mould for moulding a component with one or more inserts, the mould comprising a mould body for defining in part the shape of the component, and at least one insert holder for holding an insert within the mould body. Each insert holder is movably supported such it can move relative to the mould body in a direction of shrinkage of the component, and wherein the mould further comprises a biasing means to bias each insert holder to a first position relative to the mould body. The invention also relates to a method of moulding.

A flexible pipe body and method of producing a flexible pipe body are disclosed. The method includes providing two or more non-bonded composite filaments () as a non-bonded filament bundle (); applying a braid element () around the filament bundle () to thereby form a braided bundle () comprising non-bonded filaments (); and helically wrapping the braided bundle () around a flexible pipe body layer (). 1. A method of manufacturing a flexible pipe body comprising:providing two or more non-bonded composite filaments as a non-bonded filament bundle;applying a braid element around the filament bundle to thereby form a braided bundle comprising non-bonded filaments; andhelically wrapping the braided bundle around a flexible pipe body layer.2. A method as claimed in further comprising a step of curing the braided bundle.3. A method as claimed in wherein the step of curing comprises curing the braided bundle after the step of helically wrapping the braided bundle around a flexible pipe body layer.4. A method as claimed in wherein the non-bonded filaments comprise partly cured polymer claim 1 , uncured polymer claim 1 , cured polymer claim 1 , metal claim 1 , epoxy resin claim 1 , an elastomer claim 1 , or a combination thereof.5. A method as claimed in further comprising a step of applying a lubricant or resin or matrix material to the non-bonded composite filaments.6. A method as claimed in further comprising a step of applying a matrix material to the braided bundle.7. A method as claimed in claim 6 , wherein the step of applying a matrix material to the braided bundle is performed prior to the step of helically wrapping the braided bundle around a flexible pipe body layer; and further comprising a step of applying an additional layer to the braided bundle prior t the step of helically wrapping the braided bundle around a flexible pipe body layer.8. A method as claimed in further comprising:applying a separation layer around at least part of the filament bundle prior to ...

Peel ply, method of surface preparation and bonding composite structures using the same

Номер: US20170066226A1

A resin-rich peel ply that does not leave behind residual fibers after peeling and can work well with different resin-based composite substrates. The resin-rich peel ply is composed of a woven fabric impregnated with a resin matrix different from the resin matrix of the composite substrate. The peel ply is designed such that, upon manual removal of the peel ply from the composite substrate's surface, a thin film of the peel ply resin remains on the composite substrate's surface to create a bondable surface capable of bonding with another composite substrate, but no fibrous material from the woven fabric remains on the same surface.

The invention relates to modifying synthetic fiber sponge, such as polyester or polyurethane foam, with an epoxy-, polyester, or acrylic-resin to induce an engineered rock product for use as stone replacement in a variety of applications. The method for manufacturing comprises: producing a foam block; shaping the foam block into any regular or irregular shape; weathering the shaped foam block; infusing the weathered foam block with a resin; curing the infused foam block; and finishing the cured foam block. The artificial rock comprises a foam block shaped to resemble a rock, an exterior of the foam block infused with a resin.
