A sound-attenuating composite component comprising a honeycomb and in each case at least one insert body in at least some honeycomb cells, and a production method therefor. The respective insert body has a main axis, a first end, a second end, and a cohesive surface and is inserted with the main axis in the direction of the honeycomb depth. The cohesive surface has surface regions spaced from one another in the axial direction and which face one another and overlap in a projection onto a plane lying perpendicular to the main axis in order to demarcate a passage for sound waves in the axial direction. The course of the cohesive surface through these surface regions from the first end to the second end encircles and/or repeatedly crosses the main axis.

The invention relates to a sandwich composite component (1) for the interior of a passenger aircraft. One problem to be solved by the invention is that of proposing a cost-effectively produced sandwich composite component which is suitable for the interior of a passenger aircraft and fulfils current fire protection requirements. The layer structure of the sandwich composite component (1) according to the invention comprises: a core layer (10) made of polymer foam; a reinforcing layer (20) comprising fiber composite material; and in addition at least one functional layer (50); wherein said layers of the layer structure are integrally bonded to each other, in particular by an adhesive bond. The fiber composite material of the reinforcing layer (20) comprises a woven or laid fabric made of reinforcing fibers and a polymer matrix, which has a higher density than the polymer foam of the core layer (10). Furthermore, the at least one functional layer (50) comprises a metal foil, in particular an aluminium foil, which has a thinner layer thickness than the reinforcing layer (20).

A honeycomb for curved surface lightweight components includes a plurality of elongate ribbons and connecting regions. The connecting regions are provided, respectively, between opposing ribbons to connect the ribbons together in a portion-wise manner in a firmly bonded relationship in a transverse direction. The connecting regions are arranged at regular spacings along the longitudinal direction of a ribbon. Honeycomb-like cells form cavities between the ribbons. With respect to three successive ribbons, a displacement of the connecting regions between first and second ribbons relative to the connecting regions between second and third ribbons toward a first side of the longitudinal direction is lesser than toward a second side of the longitudinal direction. Consequently, at least a part of the cells in cross-section in the longitudinal direction/transverse direction plane have at least one longer limb corresponding to the greater displacement and at least one shorter limb corresponding to the lesser displacement.

A honeycomb for curved surface lightweight components includes a plurality of elongate ribbons and connecting regions. The connecting regions are provided, respectively, between opposing ribbons to connect the ribbons together in a portion-wise manner in a firmly bonded relationship in a transverse direction. The connecting regions are arranged at regular spacings along the longitudinal direction of a ribbon. Honeycomb-like cells form cavities between the ribbons. With respect to three successive ribbons, a displacement of the connecting regions between first and second ribbons relative to the connecting regions between second and third ribbons toward a first side of the longitudinal direction is lesser than toward a second side of the longitudinal direction. Consequently, at least a part of the cells in cross-section in the longitudinal direction/transverse direction plane have at least one longer limb corresponding to the greater displacement and at least one shorter limb corresponding to the lesser displacement.

The invention relates to a honeycomb (120… 420), in particular deformable honeycomb, for example for lightweight components having a curved surface. The honeycomb comprises elongate strips (122...422) and a plurality of connecting regions (123... 423) each provided between two opposite strips, which connecting regions connect the strips integrally to one another in sections in the transverse direction (W) and are arranged at regular intervals along the longitudinal direction (L) of a strip at a periodic center spacing (I). Honeycomb-like cells (124… 424) form hollow spaces between the strips. The invention is characterized in that based on three successive strips (122…, 422) an offset (SI') of the connecting regions between the first and second strips (122-1, 122-2… 422-1, 422-2) in relation to the connecting regions between the second and third strips (122-2, 122-3… 422-2, 422-3) towards a first side (D1) of the longitudinal direction (L) is considerably smaller than towards the other, second side (D2) of the longitudinal direction (L). In this way, in cross section in the L/W plane, at least some of the cells (24) have a shape having at least one longer limb (S2) corresponding to the greater offset and preferably at least one shorter limb (S1) corresponding to the smaller offset.

The invention relates to a multi-layer, expandable sleeve (100) for a printing press cylinder, particularly for flexographic printing. The sleeve has an inner layer (110) with a hard surface inner jacket (112), which defines a longitudinal axis (A) and the cavity for mounting on the cylinder, and an outer layer (130) with a cylindrical outer jacket (132) for carrying an outer shell, a printing plate or a separate outer sleeve, in particular. An intermediate layer (120), manufactured in the form of a lightweight honeycomb having honeycomb cells oriented radially (B) to the longitudinal axis (A), is provided between the inner jacket (112) and the outer jacket (132).

The proposed manufacture of a hollow body of fibre plastic composite comprises the preparation of a preform assembly in the form of a braid (12) of dry reinforcing fibres braided, using a braiding technique, around a self-supporting soluble core. The soluble core (10) is manufactured from a liquid-dispersible shaping material. The manufacturing comprises the impregnation of the reinforcing fibres with curable matrix material in the resin-infusion process, i.e. the matrix material is sucked into a space by the action of reduced pressure, said space being delimited without solid negative mould tooling by a vacuum film (30). After partial or full curing of the matrix material, the soluble core is removed by dissolution with liquid.

In order to join two parts (1, 2), especially two planar parts for forming panels, said two parts (1, 2) comprise at least two profiled elements which can be welded together and each of which is provided with an upper covering area (4, 4') and a lower covering area (5, 5') at least in the region of longitudinal edges (3, 3'). A pressure applied by the welding tool during friction stir welding acts substantially perpendicular to the covering areas. The profiled elements encompass clamping elements (10, 20) via which the profiled elements can be joined together. Said clamping elements are embodied such that the pressure is deflected at least in part into a horizontal force via the clamping elements, said horizontal force pressing or moving the profiled elements against or towards each other. The longitudinal edges of the upper covering area are supported on the longitudinal edges of the lower covering area by means of a single supporting element (30) and/or are placed vertically on top of each other relative to the covering areas, thus allowing also very large parts to be welded together in a simple manner.
