A method for producing a partially contoured, fiber-reinforced plastic profile includes providing a plurality of first reinforcing fibers. The first reinforcing fibers are combined to produce a uni-, bi-, or tridirectional fiber bundle. The fiber bundle is impregnated with a first plastic matrix. The impregnated fiber bundle is supplied to a unit for at least partial shaping or for at least partial shaping and at least partial curing of the first plastic matrix to produce a fiber-reinforced plastic base element. Second reinforcing fibers are provided for at least partial application to the fiber-reinforced plastic base element. The fiber-reinforced plastic base element is provided with the second reinforcing fibers for at least partial fiber-reinforced profiling and/or shaping to produce an at least partially contoured, fiber-reinforced plastic strand and the at least partially contoured, fiber-reinforced plastic strand is cut to produce an at least partially contoured, fiber-reinforced plastic profile.

A method of forming a fiber-reinforced composite part includes forming a composite preform by extruding a hollow metal shape onto a fiber-reinforced preform at an extrusion temperature and cooling the hollow metal shape from the extrusion temperature to a temperature less than the extrusion temperature. Heat from the hollow metal shape cooling from the extrusion temperature is conducted into the fiber-reinforced preform for curing thereof. Also, thermal contraction of the hollow metal shape onto the fiber-reinforced preform applies a consolidation pressure on the fiber-reinforced preform for curing thereof. The fiber-reinforced preform may be a hollow fiber-reinforced preform and a die can be moved through the hollow fiber-reinforced preform such that consolidation pressure is applied thereto by a combination of the thermal contraction of the hollow metal shape onto the hollow fiber-reinforced preform and the die moving through the hollow fiber-reinforced preform.

A new method of curing polymer thermoset materials for use in down-hole production system sucker rod protection devices is disclosed.

A fiber reinforced plastic (FRP) molding system in which FRP material, having stacked prepregs, is molded to manufacture an arc-shaped FRP component. The FRP molding system comprises inner and outer jig plates, a partial pressing device, and transfer devices. The jig plates are arc-shaped members having outer and inner surfaces that respectively fit with inner and outer surface shapes of the FRP component. The FRP material is sandwiched between the jig plates to form an integrated jig plate. The partial pressing device intermittently compresses a portion of the integrated jig plate in a radial direction orthogonal to an arc of the FRP component so that the FRP component is partially molded. The transfer devices intermittently move the compressed portion of the integrated jig plate by the partial pressing device. By repeating the partial pressing and the transport, the entire integrated jig plate is compressed to form the FRP component.

A magnet embedded core is manufactured in a stable manner even when using a die clamping device having a large rated clamping force by preventing an excessive pressurizing force from being applied to a laminated iron core, performing the clamping with an appropriate pressurizing force so to minimize leakage of the resin out of magnet insertion holes, and suppressing a reduction in the geometric and dimensional precision of the laminated iron core. A die clamping device for driving a moveable platen in a direction toward and away from a fixed lower platen is configured to include a toggle link mechanism. In a fully extended state of the toggle link mechanism, an upper die abuts an end surface of the laminated iron core to close openings of the magnet insertion holes and pressurize the laminated iron core in a laminating direction.

Composite laminate structures are produced using partially cured parts. Partial curing of the parts is achieved by applying a catalyst to regions of the parts that are to be fully cured. These regions cure at a lower-than-normal temperature while remaining regions of the part remain uncured, allowing them to be co-bonded or co-cured to other structures.
