Abstract: A method of making a cold cured composite molded article utilizes a mold requiring pressure in only one dimension. The mold is filled with a composite material and closed. The mold is then inserted between two series of rollers, wherein the rollers are positioned at a specified distance from each other such that the proper amount of pressure is applied to the mold. The mold is propelled through the two series of rollers by motorizing at least some of the rollers. The cure time is controlled by controlling the speed at which the mold is propelled through the two series of rollers.

Abstract: An anti-vegetation system for retarding growth around a structure extending from the ground includes a plurality of mats. A first mat includes at least one predefined scoring pattern to accommodate the shape of the structure extending from the ground. A plurality of scoring patterns can be included to accommodate a variety of shapes and sizes. When a scoring pattern it utilized, and the corresponding portion optionally removed, the mat can be positioned on the ground and partially around the structure extending from the surface. A second mat is positioned adjacent to the first mat and effectively surrounds the structure extending from the ground. Additional mats can be placed adjacent to the first and the second mat to increase the size of the protected area. Adjacent edges can utilize corresponding outwardly extending lips to improve the sealing efficiency of the edge-to-edge regions.
