Researchers have found a way to create industrially important thermoset polymer and fiber-reinforced polymer composite products at considerably lower expense than has been possible before. The approach could create products such as shaped composite panels for airplane fuselages using 10 orders of magnitude lower energy than current industrial manufacturing techniques. And the resulting polymers and
Engineers at the U.S. Army Research Laboratory and the University of Maryland have developed a technique that causes a composite material to become stiffer and stronger on-demand when exposed to ultraviolet light. This on-demand control of composite behavior could enable a variety of new capabilities for future Army rotorcraft design, performance and maintenance. ARL”s Dr.
AFRL Materials and Manufacturing Directorate researchers recently took advantage of a unique and rare research opportunity to better understand the behavior of materials used in the additive manufacturing process. Once a little-known curiosity, the popularity of additive manufacturing, or 3-D printing as it is commonly known, has increased in recent years, both among researchers and
