Title: The Innovations of Robert W. Mitchell
Introduction
Robert W. Mitchell is an accomplished inventor based in Hawthorne, CA (US). He is known for his significant contributions to the field of materials science, particularly in the development of high modulus fabrics. His innovative approach has led to advancements that enhance the properties of these materials, making them more effective for various applications.
Latest Patents
Mitchell holds a patent for a "Method and apparatus for producing high modulus bixial fabric." This invention focuses on improving the transverse properties of high modulus fabrics, such as graphite. The process involves continuously processing the material through a multiple roller unit under warp tension while restraining fill shrinkage. By wrapping the material no less than 180 degrees around each roll and controlling the inter-roll span, the invention allows for significant stretching of graphite precursor fabrics, such as polyacrylonitrile (PAN), by as much as 45% in the warp direction with minimal shrinkage in the fill direction. The invention also addresses simultaneous stretching and preoxidation of the precursor fabric under tension while minimizing fill shrinkage.
