With a total of 5 patents to his name, Ethridge has developed innovative solutions that enhance manufacturing processes and material properties.

Latest Patents

One of Ethridge's latest inventions is the Package Wind Cutter. This improved package wind cutter features a specially configured guide hook that is carried on the periphery of a reduced diameter winder dome. This design eliminates the need for a pressure roller mounted internally of the winder dome, simplifying the manufacture, operation, and maintenance of the apparatus. It also significantly improves the strand distribution characteristics of the cutter as the relative speed of the cutter reel and winder dome are varied. The improved guide hook efficiently passes the strand from the dome to the reel with minimal separation from both the reel and the remaining pressure roller.

Another notable patent is the Weaving Process Utilizing Multifilamentary Carbonaceous Yarn Bundles. This invention provides an improved multifilamentary tow of carbon fibers with a novel physical configuration that enhances its ability to undergo impregnation with a matrix-forming resin, resulting in high-quality composite articles. The individual filaments of the tow are randomly decollimated and commingled, creating numerous filament cross-over points throughout the length of the multifilamentary tow. This design allows for a multitude of interstices between adjacent filaments, which are well-suited to receive and retain a matrix-forming resin. The tow typically comprises approximately 1,000 to 50,000 filaments and contains at least 70 percent carbon by weight.
