A tie rod suitable for use with known concrete forming systems is constructed from a non-metal fiber, such as fiberglass, that is wound about a pair of opposed thimble elements. The resultant tie rod is as strong as a metal tie rod without the drawbacks of conventional metal tie rods. Each of the thimble elements has a main body having a channel formed in an outer surface of the main body, and the fiberglass fiber is disposed within the channel when wound thereabout.

A method for manufacturing a composite pressurized-fluid vessel including winding a first polyolefin resin-based tape thereby forming a first layer of the vessel, depositing an intermediate second layer on the first layer, consisting of a material having variable permeability properties depending on the temperature and permeability below a pre-determined temperature threshold and non-permeability above the temperature threshold, winding a second resin-based tape on the intermediate second layer thereby forming a third layer, and cooling the intermediate second layer to a temperature below the temperature threshold while the first and third layers are each kept at a temperature above the melting temperature of their resin. Wherein the tape forming the third layer is based on a different resin from the first layer and during the step of depositing the intermediate second layer.

A core system for the production of a fiber composite component includes at least two core elements which are coupled to one another and are displaceable relative to one another. At least one core element has a surface which is oblique to a displacement direction. A method for producing the fiber composite component uses the core system.

A dynamic correction system of a manufacturing process using wire is provided. The dynamic correction system includes a driving device, a path sensor, and a controller. The driving device is configured to: drive a carrier with a motion parameter and encapsulate the carrier with a wire. The path sensor is configured to obtain an actual path information of the wire encapsulating the carrier. The controller is configured to: obtain an actual path of the wire encapsulating the carrier according to the actual path information; obtain an actual path difference between a target path and the actual path; determine whether the actual path difference is greater than a predetermined error; and, when the actual path difference is greater than the predetermined error, control the driving device to change the motion parameter to cause the actual path of the wire encapsulating the carrier to approach the target path.

A fishing rod includes a rod section and a fitting having a securing portion, the fitting being firmly secured to the rod section without inhibiting bending of the rod section, the securing portion having an excellent outer appearance. On a securing portion of a fishing line guide placed on the rod section, a prepreg sheet formed of plain-woven reinforcement fibers impregnated with a thermosetting resin is wound to secure the fishing line guide. The prepreg sheet is wound and secured so that, with respect to an axial direction, reinforcement fibers are in oblique directions, and intersecting angles of the reinforcement fibers in a winding region on a part of the rod section located beyond a distal end of the securing portion are smaller than those of the reinforcement fibers in a winding region on the securing portion.

A method of making a carbon fiber wave spring includes forming a disc-shaped ring from prepreg carbon fibers. The disc-shaped ring is then formed into a desired wave shape. The disc-shaped ring in the wave shape is then cured to form a wave spring.

A three-point suspension link for a chassis of a vehicle has two arms and a central bearing area. Each arm has a bearing area. The three-point suspension link comprises two load-introducing elements, a central load-introducing element, a stabilization layer, a core element and a supporting winding. The stabilization layer and the supporting winding are formed from a fiber reinforced plastic composite material. A load-introducing element is arranged at every bearing area. The central load-introducing element is arranged at the central bearing area. The core element is surrounded by the stabilization layer in a subarea. The supporting winding surrounds the load-introducing elements, the central load-introducing element, the stabilization layer and the core element in a subarea.

A method, apparatus, and system for winding a filament around a substrate includes mounting the substrate to a rotatable structure and rotating the substrate to wind the first filament around the substrate in a first winding orientation that winds the first filament around a first pair of edges of the substrate to wrap a first filament layer around the substrate. The method further includes changing winding orientations of the first filament from the first winding orientation to a second winding orientation by turning the first filament about a corner of the substrate and winding the first filament around the rotating substrate in the second winding orientation that winds the first filament around a second pair of edges of the substrate, wherein the second pair of edges is different from the first pair of edges, to wrap a second filament layer around the substrate.
