A composite comprising a continuation polymeric phase selected from the group consisting of thermoplastic and thermoset polymers having dispersed therein a uniform and homogenous distribution of oriented short filaments derived from an anisotropic polymer, said filaments having varying lengths and varying diameters, wherein said filaments haven an average length of 0.05 cm or greater, wherein the length distribution of said filaments is from about X.+-.0.1 X to about X.+-.X wherein X is the average length of said filaments;
- and an aspect ratio of 3 or greater;
- and an average diameter greater than 0.0005 cm to about 0.1 cm, wherein the diameter distribution of said filaments is less than about Y.+-.Y wherein Y is the average diameter of said filaments.
