摘要:
Floor covering consisting of hard panels (2), whereby these panels (2) are provided, at least on two opposite edges (3-4; 5-6), with coupling means (7) made in one piece with the panels (2), so that several of such panels (2) can be mutually coupled, whereby these coupling means (7) provide for an interlocking in a direction (R1) perpendicular to the plane of the floor covering (1), as well as in a direction (R2) perpendicular to the edges (3-4; 5-6) concerned and parallel to the plane of the floor covering (1), and whereby these coupling means (7) are made such that the panels (2) can be rotated into and/or out of one another at least along the above-mentioned edges (3-4; 5-6), characterised in that the panels (2) are provided, at least on the above-mentioned edges (3-4; 5-6), near the top side, with a part from which has been removed an amount of material.
摘要:
An elastic nonwoven laminate that contains an elastic film laminated to one or more nonwoven facings is provided. The nonwoven facing contains a conventional polyolefin and can also contain a polyolefin-based plastomer. The laminate is activated by grooving to decouple the nonwoven facing from the elastic film. To reduce fiber-pull out that can result due to activation by grooving, the laminate can be post-bonded at room or elevated temperatures and a specific range of pressures to compact the fibers of the facing and minimize fiber pull-out/fuzziness while not sacrificing the softness, elasticity, and feel of the laminate.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung eines flächigen Prepreg-Materialzuschnitts (1) in einer zumindest teilweise automatisierten Fertigungsanlage, bei dem ein Fasermaterial (2) mit mindestens einem Matrixharz imprägniert wird. Es wird vorgeschlagen, dass das Fasermaterial (2) in einer Zuschnittstation (3) auf die Geometrie des jeweils herzustellenden Prepreg-Materialzuschnitts (1) zugeschnitten wird, dass nachfolgend der resultierende Faserzuschnitt (6) in einer Imprägnierstation (8) imprägniert wird und weiter nachfolgend die resultierende Prepreg-Einzellage (10) in einer Konfektionierstation (9) mit mindestens einer weiteren, zuvor in der Imprägnierstation imprägnierten Prepreg-Einzellage zu einem mehrlagigen Prepreg-Materialzuschnitt gefügt wird.
摘要:
A method and apparatus for forming a bend in composite panel. A method for forming a bend in a composite panel comprises forming a slot having a curved flange in the composite panel, inserting a sheet into the curved flange, and bending the composite panel with the slot and the sheet within the curved flange about a longitudinal axis of the slot to form the bend.
摘要:
A fiber-reinforced composite material (11) is constructed by laminating a plurality of fiber bundle layers formed of a reinforced fiber to form a laminated fiber bundle layer and further impregnating the laminated fiber bundle layer with a matrix. At either side of a neutral surface (16), the number of +¸ layers which are fiber bundle layers having a fiber orientation angle of +¸ and the number of -¸ layers which are fiber bundle layers having a fiber orientation angle of -¸ are the same, the order of laminating the fiber bundle layers is inversely symmetrical with respect to the standard surface, and the number of other fiber bundle layers disposed between the +¸ and -¸ layers at either side of the standard surface is the same.
