NASHVILLE, TENN. — A 23-foot-long highway bridge made of composite honeycomb panels won the top design award for its fabricator, Kansas Structural Composites Inc., during the SPI Composites Institute's conference.
The Composites Institute, a unit of the Society of the Plastics Industry Inc. of Washington, announced the design awards Jan. 29, as the three-day International Composites Expo '97 ended in Nashville.
Morrison Molded Fiber Glass Co. of Bristol, Va., took home three of the market-category awards.
The winning bridge carries a small county road over a creek in Kansas Structural Composites' hometown of Russell, Kan. The bridge weighs 12 tons.
The short-span bridge uses panels made of 60 percent resin and 40 percent reinforcement bonded to a composite honeycomb core.
The panels and core both are molded by a continuous-flow process, using 30 percent recycled resin, according to the Composites Institute.
Other features include a polymer concrete wear surface and composite guardrails. Its span-to-deflection ratio exceeds the range required by the U.S. Highway Bridge Code, according to the Composites Institute.
The bridge was picked from a field of 68 entries in several end-market categories.
Alpha/Owens Corning of Collierville, Tenn., supplied the polyester and vinyl ester resins. The glass fiber supplier was Vetrotex CertainTeed Corp. of Valley Forge, Pa. Brunswick Technologies Inc. of Brunswick, Maine, and ITW Plexus of Danvers, Mass., made the reinforcements.
The top award is called the Counterpoise Grand Design Award. The bridge also netted Kansas Structural Composites the Best of Market Award in the infrastructure category.
