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

The 470-class dinghy, a small, two-person monohulled racing craft, has been used in Olympic sailing competition since 1976 and, today, vacuum-infused glass fiber/polyester is the standard for hull construction. Designers of the dinghy that will be used by Marcelien De Koning and Lobke Berkhout, members of the Dutch

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

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
