09724845 · 2017-08-08 · ·

A method of making an indexed prepreg composite sheet is disclosed. The method comprises forming discrete regions in a resin film layer. The discrete regions are arranged in an indexing pattern. The method also includes forming a precursor prepreg composite sheet by impregnating a fiber reinforcement with the resin film layer having a viscosity. The discrete regions of the resin film layer form non-impregnated regions of the precursor prepreg composite sheet. The method additionally includes replacing the non-impregnated regions of the precursor prepreg composite sheet with indexing openings.

Axle Support of a Motor Vehicle
20170217502 · 2017-08-03 ·

An axle support of a motor vehicle has two longitudinal supports and at least one cross-beam which is connected to connection points with the cross-beams having body connection points in the end areas thereof. The axle support can be installed with identical dimensions in different types of motor vehicle with respect to the weight and/or drive power thereof. When using the axle support in a type of motor vehicle with a heavy weight and/or high driving power, at least one connecting point is wound with a reinforcement element made from fiber-reinforced plastic, which, in another type of vehicle with a lower weight and/or lower driving power is either not provided or is provided in smaller dimensions.

20170217056 · 2017-08-03 · ·

A portable information handling system housing fabricated from carbon fiber composite material has a PET film applied protective outer surface integrated with an in mold roll process. Heat applied to prepreg material having a polycarbonate resin aids transfer of outer surface protective material and decorative ink from a PET film during a mold insertion operation.

METHOD AND APPARATUS FOR MANUFACTURING A FORMED ARTICLE OF A COMPOSITE MATERIAL
20220266546 · 2022-08-25 · ·

A method and apparatus for manufacturing a formed article of a composite material. The formed article is manufactured by heating and pressurizing a thermoplastic resin material and fabric material. The method includes a preforming process in which the material to be formed is put in a preforming mold with a release sheet arranged between the material and a part of the preforming mold. The material is heated and pressurized to impregnate the thermoplastic resin material into the fabric material, thus forming an impregnated intermediate material. Then, in a transport process the impregnated intermediate material in a heated state is taken out from the preforming mold with the release sheet left attached thereto, and transported. Finally there is a forming process in which the impregnated intermediate material is accommodated in the forming mold and the impregnated intermediate material is formed into the formed article of the composite material by pressurizing.

Method for the adaptive filling of rigid tool cavities
11235541 · 2022-02-01 · ·

A method for the production of stiffened components made of fiber-reinforced composite material using two rigid form tools which are suitable for covering the longer end sides of T-shaped preformed reinforcing fibers, using a folded hose core and inflation of the hose core so as to exert pressure on the end side of the preformed reinforcing fibers.

Supporting profiled element, method for producing a supporting profiled element, and use of said supporting profiled element in a method for producing a reinforced vehicle fuselage component

A supporting profiled element is configured to support a reinforcing profiled element that is formed from a fiber composite semi-finished product during a curing process of a method for producing a vehicle fuselage component, during which the reinforcing profiled element is bonded to a surface of a fuselage shell that is also formed from a fiber composite semi-finished product. The supporting profiled element includes an air-impermeable profiled hose having two ends and a first end piece that is detachably inserted at a first of the two ends of the profiled hose so as to form an insertion connection. The first end piece is sealed against the profiled hose by the insertion connection.

LAY-UP HEAD
20170266894 · 2017-09-21 ·

There is disclosed a lay-up head for applying elongate fiber reinforcement material to an application surface. The lay-up head comprises a guide eyelet through which elongate fiber reinforcement material is arranged to pass into the lay-up head. The guide eyelet has an eyelet rim forming a discontinuous contact surface over which elongate fiber reinforcement material is arranged to pass.

3D-printed tooling shells

Techniques for producing panels such as for use in a vehicle, boat, aircraft or other transport structure or mechanical structure using a 3-D-printed tooling shell are disclosed. A 3-D printer may be used to produce a tooling shell containing Invar and/or some other material for use in molding the panels. A channel may be formed in a 3-D printed tooling shell for enabling resin infusion, vacuum generation or heat transfer. Alternatively, or in addition to, one or more hollow sections may be formed within the 3-D printed tooling shell for reducing a weight of the shell. The panel may be molded using the 3-D printed tooling shell.

SYSTEMS AND METHODS FOR FORMING RADIUS FILLERS FOR COMPOSITE STRUCTURES

Systems and methods for forming radius fillers for composite structures are disclosed herein. The systems include a sheet-locating structure that has a support surface and a support surface edge. The systems further include a separation device, a conveyance structure, and a layup surface. The methods include locating a sheet of composite material on a first support surface and translating the sheet of composite material such that a first portion of the sheet is supported by the first support surface and a second portion of the sheet extends past the support surface edge. The methods also include separating the second portion of the sheet from the first portion of the sheet to form a strip of composite material. The methods further include conveying the strip of composite material onto a layup surface and repeating the methods to form the radius filler from a plurality of strips of composite material.
