Abstract
The present invention relates to short metal fibers. A set of short metal fibers, with an equivalent diameter ranging from 1 to 150 $(m)m, comprises entangled and curved fibers. At least 10% of the short metal fibers are entangled, whereas the length of the curved fibers is distributed according to a gamma-distribution, having an average length preferably between 10 and 2000 $(m)m.
Claims29
A set of short metal fibers, said fibers having an equivalent diameter D in the range of 1 to 150 μm, wherein said set of short metal fibers comprises curved fibers and entangled fibers, said curved fibers having an average length Lc in the range of 10 to 2000 μm, said entangled fibers having an average length Le, said Le being more than 5 times Lc, wherein at least some of said entangled fibers have a major axis which changes several times in a non-uniform manner.
