The disclosed embodiments relate to a method for repairing a damage to a thermoplastic composite element, in particular an aircraft component, wherein a socket is milled at the site of damage to the thermoplastic composite element. Then, in the socket a patch is formed from a thermosetting material containing a reinforcing phase of fabric layers and a matrix of thermosetting resin, the patch having a shape and size corresponding to the socket geometry. In the next step, the patch is cured, and finally the cured patch is glued into the socket by means of an adhesive.

A method and apparatus for the additive manufacturing of three-dimensional objects are disclosed. Two or more materials are extruded simultaneously as a composite, with at least one material in liquid form and at least one material in a solid continuous strand completely encased within the liquid material. A means of curing the liquid material after extrusion hardens the composite. A part is constructed using a series of extruded composite paths. The strand material within the composite contains specific chemical, mechanical, or electrical characteristics that instill the object with enhanced capabilities not possible with only one material.

Methods and apparatus are provided for the production of thermoplastic composite sheets whose fibers are other than perpendicular to the longitudinal axis of the sheet and which are capable of being slit into sheets, strips and/or tapes of custom widths.

A method for preparing a multi-material component including providing a fiber reinforced component, the fiber reinforced component having one or more working layers of a fiber reinforced composite material, wherein each of the one or more working layers includes one or more fiber reinforced composite material laminae. The method includes attaching the fiber reinforced component to a multi-material transition component, wherein the multi-material transition component includes a metallic component and a transition laminate includes a transition material, wherein the transition laminate includes one or more partially embedded transition laminae each having a first embedded end that is embedded in the metallic component. Also provided are multi-material transition components and multi-material components provided by the method.

A liner for a crisp plate includes ceramic nanoparticles and a polymer material combined with the ceramic nanoparticles to provide a mixture. A network of carbon nanotubes is embedded within the mixture to form a composite matrix, wherein the carbon nanotubes are unidirectionally aligned within the composite matrix.

A manufacturing method for a sports paddle, wherein a reinforcing rod is inserted into the sports paddle, so that the reinforcing rod is located across the handle, throat, and head portions of the sports paddle. In some embodiments, a priming rod is used to create a cavity in the core of the sports paddle so that the reinforcing rod can be placed in the cavity. The manufacturing process results in a reinforced sports paddle that can withstand greater mechanical stress throughout the paddle.

A method for manufacturing a fiber preform for a part, includes weaving a first core texture of elongate shape extending in a longitudinal direction and comprising, in cross section, a central portion having, on its opposite sides, two edges each including two non-interlinked fibrous portions, shaping the first texture which involves at least opening out the non-interlinked portions to form a positioning surface defined by the portions thus opened out and by an interleaved portion, situated between these opened-out portions, which can be formed by a prolongation of the central portion, and positioning a second belt texture over the opened-out lateral portions and the interleaved fibrous portion, the second texture forming a loop around the shaped first texture to define empty spaces for articulation to other parts.

A trim part, in particular for covering an airbag in a vehicle, is provided. The trim part comprises at least one outer layer, at least one hinge layer comprising at least one first break line which forms a first part of a perimeter of a flap area and is attached to a first surface of the at least one outer layer, at least one structural layer attached to a first surface of the at least one hinge layer facing away from the at least one outer layer characterized in that at least one of the at least one outer layer comprises a fiber composite material and the at least one structural layer comprises at least one second break line forming a breakthrough area corresponding to the flap area of the at least one hinge layer.

Provided are a hose excelling in a lightweight property and in fatigue fracture resistance, a method for manufacturing the hose, and a hydraulic pump. The hose includes a tube, an interior of the tube being hollow, continuous carbon fibers and/or continuous glass fibers wound around an outer circumference of the tube, and a thermosetting resin present external to the tube. The thermosetting resin has an elastic modulus from 0.5 to 10 MPa, and the continuous carbon fibers and/or continuous glass fibers are impregnated with at least a part of the thermosetting resin. The elastic modulus of the thermosetting resin is a numeric value determined by: heating the thermosetting resin for 2 hours at a curing temperature of the thermosetting resin; then subjecting the thermosetting resin to thermoregulation for two weeks under a condition of a temperature of 23 C. and a relative humidity of 55%; and then performing a measurement in accordance with JIS K7161:2019.
