Abstract

Fibrous materials and composites are disclosed.

Claims

exact text as granted — not AI-modified
1 - 4 . (canceled) 
     
     
         5 . A method comprising:
 mechanically treating a lignocellulosic material selected from the group consisting of grasses, rice hulls, bagasse, cotton, jute, hemp, flax, bamboo, sisal, abaca, straw, corn cobs, coconut hair and mixtures thereof, to produce a mechanically treated material; and   passing the mechanically treated material through a screen having an opening size of 3.175 mm (⅛ inch) or less, to provide a screened material;   wherein the screened material has a porosity of at least 70%.   
     
     
         6 . The method of  claim 5  wherein mechanically treating comprises shearing. 
     
     
         7 . The method of  claim 5  wherein the screen has an opening size of 1.59 mm ( 1/16 inch) or less. 
     
     
         8 . The method of  claim 5  wherein the mechanically treated material has a BET surface area of greater than 0.5 m 2 /g. 
     
     
         9 . The method of  claim 5  wherein the lignocellulosic material comprises corn cobs. 
     
     
         10 . The method of  claim 5  wherein the lignocellulosic material comprises bagasse. 
     
     
         11 . The method of  claim 5  wherein the lignocellulosic material comprises grasses. 
     
     
         12 . The method of  claim 5  wherein the mechanically treated material has a BET surface area of at least 1.0 m 2 /g.
