Article, more particularly hose, more particularly again charge-air hose, with an embedded reinforcement based on a polyoxadiazole

摘要

An article composed of a polymeric material, especially a material having elastic properties, which has been provided with an embedded reinforcement made wholly or partly of a textile material. In a first reinforcement variant, the textile material is polyoxadiazole (POD), a POD derivative or a POD copolymer, or, in a second reinforcement variant, the textile material is a combination of POD, a POD derivative or a POD copolymer, and at least one further textile material, or, in a third reinforcement variant, the textile material comprises a material combination of POD, a POD derivative or a POD copolymer and at least one further material which is not part of any textile group. The article is particularly a hose and more particularly a charge-air hose having an inner layer and an outer layer of a polymeric material and an embedded reinforcement, for example in the form of a POD knit.

主权项

1. An item made of a polymeric material having an embedded reinforcement, comprising a textile material, wherein
in the case of a first reinforcement variant, the textile material is selected from a POD group consisting of polyoxadiazole (POD), a sulfonated POD, and a POD copolymer, or a combination thereof, or in the case of a second reinforcement variant, the textile material is a textile material combination comprising a member of the POD group consisting of POD, a sulfonated POD, and a POD copolymer, or a combination thereof, and also of at least one further textile material which does not derive from the POD group, or in the case of a third reinforcement variant, the textile material comprises a material combination comprising a member of the POD group consisting of POD, a sulfonated POD, and a POD copolymer, or a combination thereof, and also of at least one further material selected from the group consisting of metal fibers, carbon fibers, glass fibers, and basalt fibers, or a mixture thereof; and, wherein the item has a maximum operating temperature of 260° C.; and, wherein the member of the POD group is present in a continuous filamental form.
