Composite metals in the mix?Automobile shredder operators would probably argue that they face a difficult task as it is sorting through the variety of materials used to build the average vehicle. In the future, the task could be made even more difficult if researchers at DaimlerChrysler, Auburn Auburn (ô`bərn). 1 City (1990 pop. 33,830), Lee co., E Ala.; inc. 1839. The city's economy centers around Auburn Univ.; there is some manufacturing. 2 City (1990 pop. 24,309), seat of Androscoggin co. Hills, Mich., successfully develop composite materials composite material or composite, any material made from at least two discrete substances, such as concrete. Many materials are produced as composites, such as the fiberglass-reinforced plastics used for automobile bodies and boat hulls, but the made from fused fuse 1 also fuze n. 1. A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end. 2. metal and plastic. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. an article in the company's High Tech Report, "Researchers at DaimlerChrysler ... are taking a close look at hybrid materials consisting of thin, high-strength metal profiles and thermoplastics." The "back-injection" process is described as "injecting plastic into the tool mold [so] a composite is formed in which the plastic closely surrounds the steel sheets." The goal is to create hybrid materials that are 20 percent lighter and 20 percent cheaper than all-metal components. |
