  • Fiber imbedded polymeric sponge
    Patent number: 6774152
    Abstract: A polymeric sponge includes cellulose fibers imbedded therein. The sponge is made by mixing water and cellulose fibers with a water-catalyzing prepolymer for chemical reaction thereof. The mixture is cured and granulated to size. The cellulose fibers enhance both the manufacturing process and the resulting sponge for increasing strength, durability, and performance thereof.
    Type: Grant
    Filed: August 31, 2001
    Date of Patent: August 10, 2004
    Assignee: General Electric Company
    Inventors: James Stephen Shaw, Laurence E. Stone
