ASSEMBLING FIBER-REINFORCED FOAMS
The present invention relates to a process for converting moldings. Here, a molding comprising a foam and at least one fiber (F), wherein the fiber (F) is with a fiber region (FB2) located inside the molding is at least partially divided at least once, wherein at least one fiber (F) is completely divided. The invention further relates to the thus obtainable converted molding and to a panel comprising the converted molding and at least one layer (S1). The present invention further relates to a process for producing the panel and to the use of the converted molding/the panel according to the invention as a rotor blade in wind turbines for example.
CARRIER MATERIAL LAYER
At least one example embodiment relates to a composite material. In at least one example embodiment, the composite material includes an elastic layer and a support layer. The support layer is adhered to at least a portion of the elastic layer. The support layer extends across at least apportion of a surface of the elastic layer.
Composite products
A method of forming a composite product is described. An example of the method comprises providing a layer (34) comprising a sheet-form moulding material and providing a substrate (36). The layer of sheet-form material is applied onto a surface of the substrate (36); and pressed to the substrate in a mould (30). In some examples, the substrate (36) is an open celled foam and gas and/or vapour can be displaced from the pressing region.
Device and Method for Producing a Carrier Part Having a Plurality of Fiber Bundles
A device and a method for producing a carrier part having a plurality of fiber bundles. At least one fiber bundle strand is removed from a supply with a fiber bundle conveying unit and is conveyed into its own feed channel. A suction channel associated with each feed channel is fluidically connected thereto. An air flow is generated in the suction channel, and an end portion of the at least one fiber bundle strand is conveyed into the suction channel. By moving the at least one suction channel into a working position, the end portion of the at least one fiber bundle strand is free in a working region of the device. A needle unit having at least one needle can pick up the end portion in the working region and can pull or push it through a carrier part as the needle unit moves through the carrier part.
COMPOSITE BRIDGE DECK STRUCTURAL PANEL AND METHOD OF FABRICATION
A composite structural panel for use in bridge structures, and method of manufacturing same, comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.
METHOD OF SHAPING COMPOSITE BLADE
Provided is a method of shaping a composite blade made of a composite material by curing prepreg in which reinforcing fibers are impregnated with resin. A foaming agent disposed in an internal space of the composite blade contains a plurality of foaming bodies and foaming agent resin. The foaming bodies foam by being heated. The foaming agent resin cures by being heated. The foaming bodies include low-temperature side foaming bodies and high-temperature side foaming bodies. The low-temperature side foaming bodies foam in a low temperature range during a curing step. The high-temperature side foaming bodies foam in a high temperature range corresponding to temperatures higher than the low temperature range during the curing step.
METHOD OF MANUFACTURING HEAD FIXATION DEVICE COMPONENTS
A method or process for making one or more components of a head fixation device includes preforming, molding, and finishing subprocesses. The preforming subprocess includes placing fibers onto a substrate to orient the fibers parallel to a flux of force that the component is expected to experience in use. The fiber layers are combined and can be draped over an optional core before being molded to combine the assembly with a molding material. The resultant molded preform undergoes a finishing subprocess that can include smoothing the component to remove any burrs or sharp edges from the molding subprocess.
POLYURETHANE COATING COMPOSITIONS AND THEIR USE AS GEL COATS
Polyurethane coating compositions are disclosed that include an isocyanate-reactive component that includes a polycyclic polyether polyol that is the reaction product of a reaction mixture that includes a polycyclic polyol starter, and an alkylene oxide, as well as an isocyanate-functional component that includes a non-aromatic polyisocyanate. The polyurethane coating compositions may be particularly useful as a gel coat in the manufacture of glass fiber reinforced plastics.
FRAME DEVICE AND METHOD FOR THERMOFORMING OBJECTS
A frame device for retaining and positioning sheet materials and possible reinforcing materials intended to be thermoformed to obtain objects made of composite material, comprises: a first tubular element defining internally a first vacuum chamber for grasping by aspiration a first sheet material, a second tubular element defining internally a second vacuum chamber, separate from, and independent of the first vacuum chamber and configured for grasping by aspiration a second sheet material, wherein said first tubular element and said second tubular element are fixed together permanently so as to define a grasping frame-structure configured as a single piece; in said grasping frame-structure a third vacuum chamber being defined, separate and independent of said first and second vacuum chambers, and configured for removing air from the zone that is interposed between said first and second sheet materials and which is intended for being possibly occupied by the reinforcing material/s.
A corresponding method is also disclosed.
Method for manufacturing an overhead storage compartment for an aircraft cabin
A method for manufacturing an overhead storage compartment for an aircraft cabin, including providing a shell part extending between a first end and a second end, wherein the shell part has a first edge at the first end and a second edge at the second end. A first end wall and a second end wall are provided. The shell part and the first and second end walls are assembled, wherein the first edge is attached to the first end wall and the second edge is attached to the second end wall, such that the shell part, the first end wall and the second end wall together surround an interior space. An object, to provide a simple and fast method for manufacturing an overhead storage compartment, wherein possibly little handwork is required, is achieved in that the first end wall and/or the second end wall include an undirected long fiber reinforced plastic material.
