UORGANISKE OKSYDFIBRE OG FREMGANGSMAATE FOR FREMSTILLING DERAV.

摘要

A fibre product comprising fine-diameter inorganic oxide fibres, for example alumina fibres, which can be compressed to increase the volume fraction of fibres to at least 0.25 without excessive damage to the fibres. In a preferred embodiment the fibres are nominally-continuous and essentially-aligned and such a product is made by blow-spinning through a converging duct and collection on a wind-up drum. The product may be in the form of a mat or blanket, a tape or a woven material.
