Structural component, aircraft or spacecraft, and method
A structural component for an aircraft or spacecraft, comprising: a planar member; a reinforcing member which projects from the planar member and is rigidly connected thereto; the reinforcing member comprising at least a foam layer and a cover layer, a plurality of pins extending at least through the foam layer and the cover layer, and at least the pins and the cover layer comprising a curable matrix.
Shim for a compression mold with improved sealing
A shim for a compression mold for manufacturing a component from reinforced plastic, typically from SMC, comprising a fixed molding element, a mobile molding element, and a mobile shim that can be moved by an actuator. The mobile shim comprises a conventional part made of steel but also a part made of a high expansion material with a mean coefficient of expansion that is high enough that its own expansion at the molding temperature places the shim in compression against the molding element and seals against this element, thus eliminating flash on the molded part. This material is advantageously a polyetheretherketone, or PEEK. A mold comprising this shim and a compression molding method are also disclosed.
Method for producing a framework
With a method for producing a two-dimensional or three-dimensional framework (1) with rods (2) of a composite material with fibers and a matrix, which are connected with nodes (3) to at least one other rod (2) and/or another component (29), comprising the steps of: producing the rods (2) out of a composite material, connecting the rods (2) with at least one other rod (2) and/or another component (29) at the nodes (3), the framework (1) should be manufactured inexpensively and reliably by a low technical effort. This object can be solved in a way that the rods (2) are being produced with pultrusion and/or extrusion and a pultrusion unit (6) and/or an extrusion unit (7) is moved in space such that after the pultrusion and/or extrusion the pultruded and/or extruded rods (2) are pultruded and/or extruded in each case at the required position within the framework (1).

Metal-resin joining method
A metal-resin joining method of joining a metal member to a composite material member including a fiber reinforced plastic composite material includes an applying step of applying a first adhesive that is a thermosetting adhesive to a first region between the metal member and the composite material member, and applying a second adhesive that is a thermosetting adhesive to a second region between the metal member and the composite material member, a provisional bonding step of irradiating a first irradiation region of the metal member opposed to the first region with a laser light, and heating and curing the first adhesive to provisionally bond the metal member and the composite material member together, and a main bonding step of curing the second adhesive after the provisional bonding step to bond the metal member and the composite material member together.

Fibre reinforced polymer tube
The present disclosure relates to a fibre reinforced polymer (FRP) tube, the tube comprising a plurality of concentric layers of an FRP material forming a shell of the tube. At least one blind threaded longitudinal bolt hole is provided from a transverse end surface of the shell. The bolt hole extends in at least three of the plurality of layers, a middle layer encompassing a plane passing through a center of the bolt hole, an inner layer encompassing a plane of an innermost extent of the bolt hole, and an outer layer encompassing a plane of an outermost extent of the bolt hole. The fibre filament of each of the inner and outer layers has been wound at a first angle to the longitudinal axis and the fibre filament of the middle layer has been wound at a second angle to the longitudinal axis.

Method for producing a component from organic sheets
One example method for producing a component from organic sheets may comprise placing a first organic sheet and a second organic sheet next to one another to form a component preform, forming at least one overlapping joining zone by tacking the first and second organic sheets together with a connecting part in the form of a third organic sheet, transferring the component preform to a joining tool, using the joining tool to form a joined component by connecting the organic sheets through melting and compression in the overlapping joining zone, and consolidating the joined component at least in the zone of the overlapping joining zone.
