Patent number: 6846545Abstract: A material to reduce the effects of trauma received from the impact of a projectile. One embodiment is a needle-punched, non-woven material including at least one type of ballistic fibers selected and oriented to provide a cushioning effect and maintain a high compressive restitution constant. A percentage of the fibers are oriented with at least their ends lying approximately perpendicular to the fabric plane and/or oriented to lie in a waveform generally along or parallel to the fabric plane. This enables the ends of the fibers lying perpendicular to the fabric plane to cushion the impact from the projectile by dissipating energy through compressional resistance, and the fibers along the fabric plane to reduce energy through dispersal along fiber lines, thereby reducing the trauma resulting from an impact.Type: GrantFiled: January 23, 2002Date of Patent: January 25, 2005Assignee: Auburn UniversityInventor: Howard Thomas

Patent number: 6703091Abstract: A structural lining system and a method of applying the system to the interior surface of a pipe. First, a layer of adhesive is sprayed onto the interior surface of a previously cleaned pipe. Next, strips of previously coiled unidirectional carbon fiber material are allowed to uncoil within the pipe so that side edges of the strips abut the side edges of adjacent strips and the junction where the ends of each strip come together are staggered around the pipe so that the junction for adjacent strips do not align longitudinally. If ends of the strips overlap, additional adhesive is applied between the overlapping portions. A final epoxy coating is sprayed over the strips, forming an internal liner for the pipe.Type: GrantFiled: February 28, 2002Date of Patent: March 9, 2004Inventor: Roger H. Walker

Publication number: 20020151241Abstract: In one application for remediating sediments, employing a geocomposite sheet eliminates the need for a thick cap or removal and subsequent ex situ treatment of the sediment. A geocomposite with at least one layer of reactive material is placed over the area to be remediated. A layer of available surcharge materials such as sand, gravel, or riprap covers the geocomposite. The weight of the surcharge materials causes pore water to flow from the sediment through the reactive layer or layers of the geocomposite. Contaminants may be trapped in this reactive layer or layers. A top or bottom layer, or both a top and bottom layer, may be provided to inhibit incursion from outside the sediment layer, while permitting appropriate flow direction of pore water into the reactive layer or layers.Type: ApplicationFiled: April 4, 2002Publication date: October 17, 2002Inventors: Thomas Clair Sheahan, Akram N.
