Abstract
In a process for manufacturing a whisker preform for a composite material, a dispersion of a whisker in water or an organic solvent is passed through a sieve and is filtered, and a residual wet whisker cake is dried, with or without prior compression, to produce a cake having a desired density based upon the relationship between the weight of the whisker in the dispersion and the volume of the residual whisker cake after filtration.
