Method and device for producing a fiber composite component and fiber composite component
A method and a device are provided for producing a fiber composite component. The method includes preparing a long-fiber layer; applying short fibers to the long-fiber layer; and applying a further long-fiber layer to the long-fiber layer provided with the short fibers. The device is configured to carry out the method. The fiber composite component has a layer arrangement composed of at least two long-fiber layers, wherein the layer arrangement has an addition of short fibers. The short fibers are configured and dimensioned and are applied in such a way or are in such an arrangement that propagation of tears in one of the long-fiber layers into in each case the other or an adjacent one of the long-fiber layers and/or delamination between the long-fiber layers is rendered more difficult.
Method For Producing A Composite Material Component
The invention relates to a method for producing a composite material component, comprising the following steps: providing a negative mold, fine machining of the negative mold, applying at least one functional layer by means of thermal spraying to the negative mold, applying at least one fiber-reinforced plastic layer with a curable matrix material, curing the matrix material, and detaching the composite material component from the negative mold.

Reinforced composite structure
A reinforced composite structure that includes multiple regions of different geometric configurations connected together by a transition region. The reinforced composite structure includes reinforcement fibers on at least a portion of the transition region.
Method of making an acoustic automotive part with a fiber slurry
Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such parts so as to allow large scale implementation.
3-Dimensional high-strength fiber composite component and method for producing same
A 3-dimensional high-strength fiber composite component having isotropic fiber distribution, comprising 25 to 70 wt % of high-strength, high-modulus fibers, up to 5 wt % of binding fibers, and 25 to 70 wt % of thermosetting or thermoplastic matrix. The invention further relates to a method for producing same, comprising the following steps: preparing the fibers by opening the fibers by releasing the fibers from fiber bundles, bales, or textile structures; sucking and/or blowing the opened fibers onto a three-dimensional, air-permeable tool half having the contour of this side of the component in an interactively controlled manner; pre-solidifying the obtained fiber molding in the flock box; transferring the fiber molding onto a pressing tool in the form of the contour of the air-permeable tool half of the component; bringing into contact with at least one liquid plastic; and solidifying the fiber molding by pressing in order to form a component.
Layered construction of a fibrous body
A method to produce a fibrous body that includes structures crosslinked in a fluid-permeable manner. The method includes constructing the fibrous body in layers by alternately applying a fiber-matrix material to a layer substrate and fusing each applied layer of the fiber-matrix material. The fiber-matrix material contains a matrix material and a plurality of short fibers and/or fiber particles.
Process and apparatus for producing a fibrous-containing and/or particle-containing nonwoven
The apparatus (1) for making a fibrous-containing and/or particle-containing nonwoven (NW) comprises a spinning unit (10) with a spinning head (104), a forming surface (11a) that is movable in a conveying direction (MD), and a channel (13) positioned between the spinning head (104) and the movable forming surface (11a), and formed between at least two transverse walls (14a; 14b), that extend transverse to the conveying direction (MD) and that are in the vicinity of the movable forming surface (11a), or that are in frictional contact with the movable forming surface (11a).

TRANSFER DEVICE FOR TRANSFERRING ARTICLES
A transfer device for introducing and/or removing articles to a process device includes a basic frame and a conveying unit, which is supported by the basic frame and transfers or receives articles to or from the process device. The conveying unit is designed to be movably positionable in order for the transfer device to be reversibly advanced up to the process device. The conveying unit includes an output element of a magnetic coupling and is designed for reversibly coupling the transfer device to a corresponding drive element of the magnetic coupling, the drive element being provided on the process device. When the drive element and the output element are coupled to one another, the magnetic coupling effectuates a force transmission from a drive unit of the process device to the conveying unit.
