(US5080963-A)      Mixed fibre composite structure for use e.g. in electrochemistry, is a matrix of C fibres interlocked in an interwoven among a network of fused metal fibres. A fibres make up 1-98 wt.% of the final composite, pref. 20-98 wt.% and are generally present as bundles. Metal fibres are conducting when used in an electrode. The fibres are mixed with a binder to produce a preform which is fused or sintered.    ADVANTAGE -   High surface area, variable porosity and void vol. @(15pp)    (US5102745-A)      Article comprises a network of first fibres (I) and second fibres (II), at least (I) having bonded junctions at the fibre crossing points. Pref. (I) is a first metal and (II) is the same metal as (I) or a second metal, a ceramic, a high surface area material and/or C.    Pref. the article is matrix of C fibres interwoven in a network of fused metal fibres.    USE/ADVANTAGE -   Esp. as a C-based electrode for high energy batteries, fuel cells, etc., and also as a filter, separator, (bio)catalyst and catalyst support, preform for composites, and water and effluent treatment agent. Prod. can have tailored properties esp. surface area, conductivity, catalytic activity, etc. as desired, and is easy to mfr.. @(95pp Dwg.No.1/18)@    (EP473715-B1)      Article comprises a network of first fibres (I) and second fibres (II), at least (I) having bonded junctions at the fibre crossing points.
