摘要:
A cable splice case or other article for environmental sealing comprises a composite material having multifilament fibres therein, which fibres are blocked in order to prevent passage of fluid through the material in a direction parallel to its major surfaces.
摘要:
A fabric for a printed circuit-board characterized by that it is composed of one or more fiber(s) (1A, 1B) selected from the group consisting of polyether ether ketone fiber, polyetherimide fiber and polysulphone fiber, and glass fiber (2A, 2B), and a printed circuit-board employing the fabric as its base material.
摘要:
An electroconductive thermoplastic resin sheet causing no fluffing of electroconductive fibers is provided, which sheet comprises a thermoplastic resin film; a non-woven fabric or a knitted or woven fabric consisting of hot-melt-adhesive fibers and electroconductive fibers and applied and integrally melt-adhered onto one surface or both the surfaces of the film and then subjected to surface treatment; and a coating having a curing composition composed mainly of an unsaturated resin and a reactive diluent applied onto the treated surface and crosslinked and cured and having a coating thickness of 1 to 10 µm. The electroconductive thermoplastic resin sheet is useful for packaging and in clean room technology.
摘要:
A composite material comprising a recoverable fabric and a polymeric matrix material may be recovered around a cable splice to protect it. The fabric may have multifilament glass fibres (9) in one direction which may be provided with a continuous coating (5) to prevent moisture that may travel along their length from travelling through the thickness of the composite.
摘要:
Tissu de dissipation électrostatique (10) dont la construction consiste en un tissu de base tissé ou tricoté (12, 14) ayant une structure de grille intégralement tissée ou tricotée relevée au dessus de la surface du tissu de base, améliorant ainsi les caractéristiques de dissipation électrostatique. La grille est constituée d'un fil de décharge statique (16, 18) plié en un fil porteur qui est ensuite tissé ou tricoté dans le tissu dans le sens de la chaîne, dans le sens de la trame ou dans les deux sens, permettant ainsi de produire un tissu qui présente une dissipation rapide mais contrôlée de l'électricité statique. Un tel tissu peut être utilisé pour des vêtements antistatiques, des toiles de couvertures antistatiques, des supports filtrants et autres.
摘要:
A fibrous composite material of essentially two-dimensional form in the form of individual fibres, sheets or layers comprising combustible fibres and lamellae of a layer mineral of size below 50 microns, a method for the manufacture of the fibrous composite materials by applying lamellae of a layer mineral to the fibres preferably from suspension followed by removal of the liquid phase of the suspension, and use of the fibrous composite materials for the fire-protection of substrates.

A fibrous composite material in the form of individual fibres, sheets, layers or lightweight blocks comprising non-combustible fibres and lamellae of a layer mineral, a method for the manufacture of the fibrous composite materials by applying lamellae of a layer mineral to the fibres preferably from suspension followed by removal of the liquid phase of the suspension, and use of the fibrous composite materials for the fire-protection of substrates.
摘要:
An industrial fabric used in the form of an endless fabric belt to form and convey a nonwoven fiber web during the manufacture of a nonwoven fabric has a web-supporting surface which includes rough-surface yarns which inhibit movement, namely, slippage, of the nonwoven fiber web relative to the web-supporting surface. Preferably, the rough-surface yarns make long floats in one or both directions, that is, lengthwise and/or crosswise, on the web-supporting surface.
