Claims
- 1. A process for making a composite comprising the steps of homogeneously combining aramid particles 50 to 500 microns in average diameter, substantially free from fibrils and having a surface area of less than 2 square meters per gram, and fiber reinforcing material from 1 to 6 mm in long dimension in a weight ratio of greater than 1/4 and blending that combination with a matrix resin to yield a composite having
- a) 10 to 95 percent, by weight, matrix resin;
- b) 1 to 60 percent, by weight, fiber reinforcing material;
- c) 1 to 65 percent, by weight, aramid particles.
