Abstract
Methods of making fibrous materials are disclosed that include shearing a fiber source to provide a first fibrous material, and passing the first fibrous material through a first screen. Also, composites are disclosed that includes a fibrous material, a resin and a dye.
Claims15
A method of making a fibrous material, the method comprising:
- shearing a first fiber source, selected from the group consisting of paper, grasses, rice hulls, bagasse, cotton, jute, hemp, flax, bamboo, sisal, abaca, straw, corn cobs, rice hulls, coconut hair and mixtures thereof, without dispersing the fiber source in water, to release fibers from the fiber source and thereby provide a first fibrous material;
- passing the fibrous material through a first screen having an opening size of 1/8 inch (3.175 mm ) or less, to provide a second fibrous material, the second fibrous material having a porosity of greater than 70% and a BET surface area of greater than 0.5 m2/g;
- and then
- shearing the second fibrous material again to provide a third fibrous material.

- passing the fibrous material through a first screen having an opening size of 1/8 inch (3.175 mm) or less, to provide a second fibrous material;
- collecting the second fibrous material in a receiving area having a pressure below nominal atmospheric pressure, the second fibrous material having a porosity of greater than 70% and a BET surface area of greater than 0.5 m2/g;
- and then
- shearing the second fibrous material again to provide a third fibrous material.
