The benefits of using thermoplastic composites for automotive throttle body applications was the topic presented by several Visteon (NYSE: VC) engineers to the Society of Automotive Engineers (SAE) 2001 World Congress last week.
Historically, throttle bodies, which control airflow to the engine, have been made from machined die cast aluminum. Research behind Visteon's technical paper, titled ""Lightweight Thermoplastic Composite Throttle Bodies for Car and Truck Applications,"" illustrated how replacing these metal systems with lightweight thermoplastics can be more beneficial in demanding under-hood applications.
""One of the fundamental challenges automotive engineers face is finding ways to cut total system costs and the overall weight of today's vehicles,"" said Mike Rabideau, a Visteon Senior Plastics Engineer. ""Lightweight thermoplastics meet both of these requirements, which is why we designed thermoplastic throttle bodies.""
The paper outlined many additional advantages of using thermoplastic composite for throttle body applications including: increased design flexibility enabling improved throttle body functionality; improved throttle body packaging in the engine compartment; reduction in throttle body assembly weight, improving vehicle fuel economy; simplified manufacturing process and reduction in required manufacturing floor space and flow paths; reduction in in-process inventories and scrap; reduction in direct labor; and reduction in overall tooling costs, including tooling wear.

The American Composites Manufacturers Association participated in a roundtable discussion about the IMAGINE Act. Known as the Innovative Materials in American Growth and Infrastructure, Newly Expanded (IMAGINE) Act, the new bill is designed to promote the increased use of innovative materials like fibre reinforced polymer (FRP) composites, as well as new manufacturing methods to accelerate the deployment and extend the life of infrastructure projects.
After the collapse of a drinking water pipeline in downtown Amsterdam, the Netherlands, Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment.
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
