摘要:
A method for manufacturing a sandwich component comprises the following steps: - providing a plurality of material cutouts (1, 2, 3, 4); - applying at least one matrix material to the top face and/or the bottom face of at least one material cutout (1, 2, 3, 4); - placing the material cutouts (1, 2, 3, 4) on top of and/or next to one another, at least two material cutouts (1, 2, 3, 4) being placed on top of one another, and at least two material cutouts (1, 2, 3, 4) having different shapes or matrix material being applied in different ways along the top face and/or bottom face thereof; or matrix material being applied in different ways to the top face and/or bottom face of at least one of the material cutouts (1, 2, 3, 4); such that at least one horizontal zone and/or vertical zone having mechanical properties that differ from those in other zones of the sandwich component is/are created on the sandwich component; - pressing the material cutouts (1, 2, 3, 4) together in such a way as to obtain the sandwich component. Also disclosed is an apparatus for carrying out a method of said type, comprising a multilayer holding device, in particular a fan-type gripper.

Die Erfindung betrifft ein Wabenstrukturelement mit einer mindestens teilweise geschlossenen Wabenstruktur, welche durch das Zusammenfügen mindestens zweier strukturierter Schichten (101, 201) mit einseitig offenen Wabenzellen (104, 204) gebildet ist. Die Erfindung betrifft ferner ein Verfahren zur Herstellung eines solchen Wabenstrukturelements.
摘要:
This invention refers to a method for manufacturing curved components (1) for furniture, particularly doors for furniture, comprising: a cold shaping phase of a first panel (2) made in a wooden, plastic or metal material to curve the first panel; a cold shaping phase of a second panel (4) made in a wooden, plastic or metal material to curve the second panel; a cold overlapping phase of the first curved panel, of at least one intermediate separating layer (3) and of the second curved panel by interposing glue between the intermediate layer and the first and second curved panel to make a curved component for furniture.
摘要:
The invention relates to a sandwich material comprising two top layers and a core material, wherein the core material is built up from a sandwich material consisting of layers of thermoplastic honeycomb material which are connected to each other by means of fiber reinforced plastic layers and wherein said plastic layers are at right angles relative to said top layers, and to a method for manufacturing such sandwich material.

Les portions de réparation (6, 20, 21, 22 et 23), établies à travers deux couches d'âme (16, 19), par exemple en nid d'abeille et trois peaux (2, 3, 17) en polymère, dont deux peaux externes et une peau médiane intercalée entre les couches d'âme pour donner une structure composite, sont installées et le polymère est durci sous vide. Une contre-forme (8) est appuyée sur une des peaux (2) pour garantir un bon aspect et une bonne qualité de surface. Selon l'invention, des évents (24) sont prévus à travers la peau médiane (21) et éventuellement à travers la peau (2) recevant la contre-forme pour un bon dégazage de l'âme alvéolaire sous-jacente (20).
