The invention relates to a method for producing a component (1, 2) consisting of a fibre-reinforced plastic and prepared for the welding of a metal component (4), which comprises at least one fibre element (2) impregnated with a plastic matrix, wherein at least some portions of at least one metal joining partner (1) are integrated into a fibre element, a first section of the joining partner (1) being surrounded by the fibres of the fibre element (2) such that it is in contact therewith, and a second section of the joining partner (1) projecting over a surface of the fibre element (2) or lying at least in the surface, the joining partner (1) being connected, by at least some portions, to the liquid and hardening plastic matrix, especially at least by the first section. The invention also relates to a metal joining partner for integrating into a component consisting of fibre-reinforced plastic in order to weld a metal component (4) thereto.

A machine for fabricating a fiber-reinforced component by additive manufacturing is disclosed. The machine may have a surface, a matrix feed configured to deposit a plurality of matrix layers on the surface, and a fiber feed configured to deposit a fiber layer on at least one of the plurality of matrix layers. The deposition of the plurality of matrix layers and the fiber layer may be controlled by a computer.

A fan blade platform is provided. The fan blade platform may include a wall, a first sidewall extending from the flowpath to a circular member, and a second sidewall extending from the flowpath to the circular member. A stiffening member may also extend from the circular member to the flowpath and be formed integrally with the first sidewall, the second sidewall, and the flowpath.

A surgical implant comprises a basic structure having a first face and a resorbable film attached to the first face of the basic structure. A plurality of solid protrusions emerges from the film in a direction away from the basic structure. The protrusions comprise a shape defined by a respective body and a respective head, the body emerging from the film and terminating in the head, and the head projecting laterally with respect to the body.

A core (14) which is typically held in front of the mold (13) is required for producing hollow plastic objects (10). This does not allow for a transverse reinforcement (11) which is formed from a prefabricated reinforcement tube to be pulled over the core (14). A method and device is provided for the core (14) to be held behind the mold (14) when viewed in the production direction (17). In this case, the front end (15) of the core (14), which is located in front of the mold (13), remains free, such that a transverse reinforcement (11) that has been formed from a prefabricated reinforcement tube can be pulled over the free front end (15) of the core (14).

A surgical implant (1) comprises a basic structure (2) having a first face (4) and a resorbable film (6) attached to the first face (4) of the basic structure (2). A plurality of solid protrusions (8) emerges from the film (6) in a direction away from the basic structure (2). The protrusions (8) comprise a shape defined by a respective body and a respective head, the body emerging from the film (6) and terminating in the head, and the head projecting laterally with respect to the body.

A method of manufacturing a gas tank comprises: a step (a) of preparing a liner having a hollow cylindrical shape; a step (b) of forming a first layer by winding a first fiber bundle impregnated with resin around the liner; a step (c) of forming a second layer by winding a second fiber bundle impregnated with resin around the liner with the wound first fiber bundle in such a manner that portions of the second fiber bundle overlap each other in a direction parallel to a center axis of the liner; a step (d) of causing a section where the portions of the second fiber bundle overlap each other to get into the first layer; and a step (e) of curing the resin.
