Abstract
The present invention relates to short metal fibers. A set of short metal fibers, with an equivalent diameter ranging from 1 to 150 μm, 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 μm.
Claims2
A method to provide a set of short metal fibers, comprising the steps of:
- individualizing the metal fibers by a carding operation;
- providing the set of short metal fibers by cutting or entangling and sieving the set of short metal fibers.
