A method for fabricating emulated wood with pores and fibers, comprising: immersing a plurality of synthetic fibers configured parallel in a plane into a resin so that the resin is coated on the surfaces of the plurality of synthetic fibers and in the gaps between the plurality of synthetic fibers; placing the plurality of synthetic fibers between two sheets, wherein the two sheets are planar sheets made from a uniform composition comprising a thermoplastic elastomer, a foaming agent, and a crosslinking agent; carrying out a heat-press process on the two sheets so that the foaming agent undergoes microcellular foaming and forms dense closed pores in the two sheets, and so that the composition on inner surfaces of the two sheets expands towards the plurality of synthetic fibers and penetrates through the gaps between the plurality of synthetic fibers; and cooling the two sheets to yield an emulated wood board.

A method for producing a structural component part (1) from a fiber-reinforced plastic according to a three-dimensional winding process. Threadlike or strand-shaped fiber material (12) supplied on at least one bobbin (18) is wound around at least one filament carrier (11) in at least one winding pattern by at least one computer-controlled winding device (10). The fiber material (12) is laid down on the filament carrier (11) with a filament tensile force (F.sub.ZN) that is preadjusted by a control device (14). The filament tensile force (F.sub.Zist) is controlled depending on location and/or depending on path in order to take into account specific lay-down locations (29) on the filament carrier (11) in which a lay-down path (28) predefined by the winding pattern is departed from owing to the local geometry at preadjusted filament tensile force (F.sub.ZN).

The present invention relates to a method and an assembly for manufacturing a leaf spring from a fiber-composite material. To this end, tape material from a fiber material, which has been pre-impregnated with a matrix resin, for manufacturing a semi-finished leaf spring is wound under tension onto a winding core, wherein at least two cavities for shaping are configured on the winding core. The tape material here is pressed on by way of a contact pressure means, such that adjacent layers of the fiber material are adhesively interconnected and air pockets are removed. The semi-finished leaf spring under impingement by pressure and heat and under curing of the matrix resin is finally processed to form a leaf spring.

Fiber composite components can be formed by winding fibers along tracks of a winding spool of a winding core. The fibers may either be pre-coated with a curable resin, or the curable resin may be applied to the fibers after the fibers are wound along the tracks of the winding spool of the winding core. The curable resin may also and/or alternatively be applied to a mold that receives the fibers wound about the winding spool. The curable resin may then be cured, after which the winding spool and the winding core may be removed in order to release the fiber composite component. In some cases, the winding spool may be removed from the fiber composite component by moving the winding spool inwardly towards an inside of the winding core.

A chopper disc for a device for the processing of neutron beams is made of carbon fibers and has a concentric, hollow cylindrical recess for receiving a hub for connection to a pivot bearing. The chopper disc also includes a concentric absorber area for absorbing neutrons striking the chopper disc and at least one window in the absorber area through which neutrons of the neutron beam can pass. The carbon fibers extend from the outer periphery of the chopper disc radially in the direction of the recess and contact the recess tangentially.

A steering-column assembly for a motor vehicle may include a steering spindle rotatably mounted in a steering-column tube, which steering-column tube is mounted in a console that connects the steering-column directly or indirectly to a body of the motor vehicle. At least one of the components of the steering-column, such as the console, for example, may include a fiber composite component that can be formed by winding fibers along tracks of a winding spool of a winding core, introducing a curable resin into the fibers or a mold to be used with the wound fibers, curing the wound fibers, and removing the winding spool and the winding core so as to release the fiber composite component. The fiber composite component may then be fitted into the steering column assembly.

A method for manufacturing a fibrous preform for a blade or propeller part of a turbomachine, includes at least one fixing base extended by a mounting portion of an aerodynamic profile, the method including the winding of a fibrous texture, obtained by contour weaving, on a substrate of changing section having at least a first region of extra thickness in the shape of the fixing base and a second region in the shape of the mounting portion of the aerodynamic profile.

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 carbon fiber boom structure for an agricultural sprayer boom, the boom structure including an elongated upper carbon fiber tube, at least one elongated lower carbon fiber and a carbon fiber/resin matrix uniting structure bonded to each of the carbon fiber tubes to hold the tubes in a spaced apart position. The uniting structure being formed in a winding operation by applying windings of a carbon fiber string with a liquid resin around portions of the tubes, the windings and resin matrix defining an inner primary layer and an outer primary layer, wherein the inner primary layer is bonded to a surface portion of each tube while the outer primary layer is bonded to a remaining surface portion of each tube to completely, or essentially completely, envelope each tube by the portions of the two primary layers.
