Abstract

In known honeycomb fabrics, the woven-in glass fibre rovings are axially loaded during winding to form a roll or by adaptation to a curved form. During this the rovings can kink in an uncontrolled manner out of the initial plane or their ends slip out of the fabric. Fig. 2 shows, according to the invention, an improved honeycomb fabric in which the rovings (4) deform in an undulating, well-defined manner (X1/X2) with axial loading in their initial plane (3). A pleated fabric (2) with backing fabric (1) and rovings (4) can be seen; the latter penetrate passage holes (5 and 5a) at the upper ends of the folds (2), which holes are formed by appropriate fibre guidance during weaving. The passage holes (5 and 5a) have the form of elongated holes which holes are longer than the roving diameter and each extend predominantly to one side of the neutral straight line (3) and specifically in such a manner that the large hole sections lie alternately on the two sides of the neutral line (3). All rovings (4) are thus provided with a well-defined possibility for kinking up (X1 and X2), thus eliminating the above-described difficulties. <IMAGE>

Description

Beachreibung der Erfindung Die Erfindung stellt eine Weiterentwicklung der Patentanmeldungen P 1704670 und P 2052431.6-16 dar.Description of the Invention The invention represents a further development of patent applications P 1704670 and P 2052431.6-16.

Bei diesen Anmeldungen werden Gewebe zur Verstärkung von gunsthar laminaten dargestellt, welche dadurch gekennzeichnet sind, daß ei flächiges Trägergewebe mit Fasersträngen rippenartig verbunden wi Weiter wird in P 2052431.6-16 erwähnt, daß die Faserstrangrippen auch eine mehr oder weniger gewellte und flexible Verformbarkeit aufweisen können; dadurch werden die Rippengewebe besser aufrollb biegsvaer, u. beim Laminieren verformbarer.In these registrations, fabrics are used to reinforce gunsthar Laminates shown, which are characterized in that egg flat carrier fabric rib-like connected with fiber strands wi Further is mentioned in P 2052431.6-16, that the fiber strand ribs also have a more or less corrugated and flexible deformability may have; as a result, the rib fabrics are better rolled up bendable, u. more malleable during lamination.

Für die Schußplissewebtechnik jedoch ist die Technik der Rippenverformbarkeit nicht erwähnt.For the weft pleated weaving technique, however, is the technique of rib deformability not mentioned.

Nun ist es aber so, daß bei der Verwendung der Schußplissewebtech besonders hohe Rippen möglich sind; wodurch die Verformbarkeit der Rippen zwingend notwendig wird.But now it is the case that when using the Schußplissewebtech particularly high ribs are possible; whereby the deformability of the ribs is mandatory becomes necessary.

Figur 2) zeigt ein "weitmaschig gewelltes" Plissewabengewebe in Karo form.Figure 2) shows a "wide-meshed, corrugated" pleated honeycomb fabric in plaid shape.

1) ist das Trägergewebe.1) is the carrier fabric.

2) Sind die Schußplisse-Falten.2) Are the weft pleated folds.

3) Sind gedachte gerade verlaufende Hilfslinien.3) Are imaginary straight lines.

4)Sind die ganz oben in die Plisse-Falten eingewebten Kettrovings (Glasfaserstränge), dessen Einbindung und Wellung sich über 4 Plisse-Falten erstreckt bzw. sich wiederholt.4) Are the warp rovings woven into the pleated folds at the very top (Glass fiber strands), the integration and corrugation of which extends over 4 pleated folds or repeats itself.

Diese Art der Kettroving-Einbindung bewirkt eine großbogigere u. damit flexibqlere wellung (mit weniger Kraftaufwand) als bei Figur 1. This type of warp roving integration causes a larger arch u. thus more flexible corrugation (with less effort) than in Figure 1.

5) und 5a) Sind 2 unterschiedliche, webtechnisch erzeugte Langlöcl welche beidseitig der gedachten Linie 3 wechselweise angeordnet sind, wodurch die Kettrovings bei flacher Gewebelage bereits eine leichte Wellung mit den Maßen xl und x2 erhalten.5) and 5a) Are 2 different, weaving-technically generated long holes which are arranged alternately on both sides of the imaginary line 3, whereby the Warp rovings with a flat fabric layer already have a slight corrugation with the dimensions xl and get x2.

Bei der Verformung des Plisse-Qaben -Gewebes (z.B. beim Aufrollt knicken nun die Kettrovigs nicht mehr ab od. schieben an den Schnittstellen aus dem Gewebe heraus, sondern können ihre Längendifferenzen durch mehr oder weniger Wellenbildung ausgleichen. When the pleated Qaben fabric is deformed (e.g. when it is rolled up The Kettrovigs no longer bend or slide out at the interfaces the tissue out, but their length differences can be greater or lesser Compensate for wave formation.
