DuPont will begin production of an innovative high-performance material with Kevlar that they say will offer consumers and industry performance breakthroughs in a range of rubber-based products.
The new material is a composite of Kevlar pulp and an elastomer. According to DuPont, the Kevlar provides significant performance improvements in this new form in products such as automotive, motorcycle and bicycle tires, hoses and belts, seals and gaskets, rubber-covered rolls, pump liners, diaphragms and moulded goods. More specifically, it helps improve properties such as modulus and wear resistance without having a negative impact on other critical rubber properties.
""This new composite relies on the same molecular science found in DuPont Kevlar high-performance material that is recognized around the world for its unique strength, durability and light weight,"" said Dr. Roger Siemionko, vice president of technology -- DuPont Safety and Protection. ""The composite provides both the strength and flexibility required for rigorous applications. For the future, we're seeking to build on this success and go beyond manufacturing to also perform significant development work that will expand this process to other applications.""
Prior research into the use of the engineered elastomer with Kevlar in automotive tyres, for example, showed significant improvements in ride and handling, reduced rolling resistance and heat generation, and increased durability. Increased wear resistance is of special environmental interest, since it can help to extend the life of the tire. Similar results were achieved in bicycle and motorcycle tires, which also demonstrated improved puncture resistance.
Production will take place at the company's research and development centre in DuPont Canada's Kingston Centre.
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).
