- Highway bridge built of composites.
Composites, typically used to construct submarines, fighter aircraft, and spacecraft, will be used to build a cable-stayed highway bridge. Lockheed Palo Alto Research Laboratories has joined a consortium headed by the University of California at San Diego (UCSD) to design and build the 450-foot-long bridge across Interstate 5 at the ......
- New blades hike airplane safety
San Diego-The next generation of turbine fan blades should significantly improve safety and reliability, reduce noise, and lower maintenance and fuel costs for commercial and military planes because engineers will craft them from carbon composites. Initial feasibility tests by University of California at San Diego (UCSD) structural engineers, NASA, and ......

- A fix for aluminum overheads: using innovative
fiber-reinforced polymer repairs to correct distress in welded joints on
aluminum sign structure trusses.
In the early 1960s, State departments of transportation (DOTs) began using aluminum trichord overhead structures to support signs along our Nation's highways. The advantages of using aluminum were obvious. It is lightweight, costs less than steel, and is inherently resistant to rusting. In 1994, however, the American Association of State ......

- Characterizing the failure of composite
structures.
When two or more materials combine to create a better material system, they form a composite. In a broad sense, metal alloys and plastics are composites, but their constituent materials are combined at the microscale. In a narrower sense, a composite material is one in which the constituent materials are ......
