Cast polymer concrete structures save city's sewers
Beneath its historic colonial charm, Charleston, S.C. had an underground sewer system in need of repair. Engineers at U.S. Composite Pipe (Alvarado, Texas) devised a solution that included unique cast polymer composite sewer interceptor structures — 10-ft/3m-diameter vertical access shafts that extend as far as 110

Airbus Industrie (Toulouse, France) wanted to cut cycle time off the production of interior storage bin doors for its A320 and A380 commercial airplanes and identified part cooling in the mold as the most likely source of potential time savings. The doors, about 1m long, are fabricated of a glass fiber prepregged with

Dr. Don Adams (Wyoming Test Fixtures Inc., Salt Lake City, Utah) follows up his HPC January 2008 discussion of double-shear testing of a single fastener while advice about testing multiple fasteners under single-shear loading conditions.
Read MoreStartup struggles
A week before Adam Aircraft made the somewhat surprising announcement that it had run out of cash and couldn’t find anyone to lend it money, I found myself on the phone with one of the company’s composites design engineers. We were discussing trends in composites design for aerospace, aerospace design challenges, and

Who wouldn’t give $105,000 to gain $222 million? Lockheed Martin Aeronautics Co. (LMAC, Ft. Worth, Texas) did and in the process was able to fabricate dimension-critical aerostructures more efficiently, more accurately, and faster. LMAC is a major components manufacturer for the F-35 Joint Strike Fighter (JSF), the

More attention is being focused on fabricating processes for aircraft structures that can save time and money and improve efficiency while yielding high-quality parts. Historically, nearly all aircraft designers have assumed autoclave cure as the norm, despite the well-documented cost and time advantages of
