The invention relates to a pallet (1), comprising a basic body (10) with a first panel (11), a second panel (12) and a layer (13) having a plurality of tube segments (14) which is arranged between the panels (11, 12), wherein the layer (13) has at least one cutout (131) which is continuous in the direction of a pallet height (HP), and wherein the first panel (11) has at least one first opening (111) which at least partially overlaps with the at least one cutout (131). The invention further relates to a foot (16) and a runner (17) for a pallet (1), to a sandwich block (2) for producing a layer (13) of a pallet (1), and to a method for producing a pallet (1).

A method of manufacturing a composite core can include: wrapping a mandrel in a mandrel wrapping process by securing a mandrel with a winding jig; orienting the composite material at a wrap angle to the mandrel; and depositing the composite material around a circumference of the mandrel. The method can further include assembling the wrapped mandrels in a tool and applying a pressure to the composite material during a curing cycle.

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 hierarchical sandwich core in the form of a honeycomb, i.e. having repetitive and periodic lattice materials. The sandwich core can be made up of a macroscopic honeycomb structure with sandwich cell walls having a mesoscopic cellular core. The longitudinal axis of cells of the mesoscopic honeycomb cell can be perpendicular to the longitudinal axis of the cells of the macroscopic honeycomb structure. Alternatively, if a foam core is used having mesoscopic cells the shape of the mesoscopic cells can be made during the foaming process so that they are elongate in a direction perpendicular to the longitudinal axis of the cells of the macroscopic honeycomb structure.

According to the present disclosure there is provided a method of forming a first structure (150), comprising the steps of: providing one or more slots (124) in a material, thereby to define a plurality of strips (122) of the material, the slots (124) defining a series of connecting elements (128) connecting adjacent strips (122) of the material, the connecting elements (128) being spaced apart along a first direction (130), forming the material to provide: an array of oppositely oriented channels (152), each channel (152) extending in a second direction perpendicular to the first direction, and the array itself extending in the first direction, each channel comprising a base, and sides extending from the base; and a first, non-continuous, outer plane; and a second, non-continuous, outer plane, such that the first structure is foldable along each of the series of connecting elements about the first direction to bring the first outer plane of a first strip toward, and optionally into contact with, the first outer plane of a second, adjacent strip.

An apparatus for the manufacture of a panel of individual cellular compartments from an elongate sheet of flexible material. The apparatus comprises first and second rod banks and a feed head reciprocally moveable longitudinally and generally parallel along the rod banks. The feed head applies the flexible material about the exterior side surfaces of the rods of one of the rod banks when moving in one direction, and applies the flexible material about the exterior surfaces of the rods of the other of the rod banks when moving in the opposite direction, to thereby apply sequential layers of the flexible material to the exterior surface of the rods of the rod banks in an alternating fashion. The sequential layers of flexible material are secured to one another at points of contact along the length of the rods to form successive rows of conjoined compartments that form a panel.

A buffer forming machine includes a frame and a roller unit. The roller unit includes at least two friction wheel sets spaced apart from each other, one of the at least two friction wheel sets defining a feed region, another one of the at least two friction wheel sets defining an output region. A ratio of a height of the output region in the height direction to a height of the feed region in the height direction is greater than 70%. The height of the feed region in the height direction is configured to be 90-95% of a height of each of the plurality of sheet materials in the height direction. The height of the output region in the height direction is configured to be 70-75% of the height of each of the plurality of the sheet materials.

A buffer forming method comprises following steps of: providing a honeycomb core, and providing a roller unit to clamp the honeycomb core for continuous pressing and conveying in a stretching direction, and to make the honeycomb core become a buffer through a feed stage, a shaping stage, and a rebound stage. The roller unit defines a feed region, a distance of which is greater than 70% of a height of a sheet material and the distance of which is smaller than the height of the sheet material, in order to make an average bending deformation degree of a plurality of intermediate segments of the honeycomb core substantially smaller than 10% in a pressing and conveying process.
