  • Hemp Fiber Reinforced Composite with Recycled High Density Polyethylene and Production Thereof
    Publication number: 20170121473
    Abstract: Novel structural materials composed of industrial hemp fiber with recycled high density polyethylene (HDPE) as well as methods for the production of the same are disclosed. The material's mechanical strength outperforms that of conventional lumber and could compete with glass fiber reinforced composites, particularly in tensile strength. In addition, this material offers many other significant advantages including insect free, high moisture resistance, no harmful chemical treatments, and no rapid corrosion in water environments.
    Type: Application
    Filed: January 10, 2017
    Publication date: May 4, 2017
    Applicant: University of North Carolina at Charlotte
    Inventors: Na Lu, Ralph Robert Johnson
