Title: David A. Evans: Innovator in Composite Materials
Introduction
David A. Evans is a notable inventor based in Lowell, MA (US), recognized for his contributions to the field of composite materials. With a total of 3 patents, he has made significant advancements in the production and application of high-quality composite materials.
Latest Patents
One of his latest patents is titled "Hybrid composite articles and methods for their production." This invention focuses on creating high-quality composite materials from fibrous materials, incorporating a polymer matrix that embeds individual fibers. The polymer matrix is derived from polymer particles that penetrate into a strand, filling gaps between the fibers. This process can be achieved by exposing the strand to a stable emulsion of the polymer particles. The resulting composite structures allow for the use of inexpensive and readily available scrap materials, resulting in lightweight materials that exhibit enhanced strength and durability.
Another significant patent is "Composite articles including prepregs, preforms, laminates and sandwich moldings, and methods of making the same." This invention also emphasizes the creation of high-quality composite materials from fibers such as glass, polyaramid, or graphite fibers. The polymer matrix in this case is a thermoplastic or other polymer type that can effectively penetrate gaps between individual fibers. The invention outlines methods for forming composite materials and describes composite sheets and articles, including new composites for porous materials like ceramics or wood.
