Advanced Technologies Supplement: Processes Reduce Composite Costs April 1, 2007 Composites engineers are expanding their craft to build more complex, durable parts at higher production volumes. One way they are achieving this objective is by using infusion-molding processes based on Resin Transfer Molding (RTM) and Vacuum Assisted Resin Transfer Molding (VARTM).
Micromanufacturing is Growing July 1, 2004 Many industries have been making parts with micron dimensions for some time, but in the last few years, the market for miniaturization has expanded. The demand is not only for small parts, but also for small complex features on larger parts. This is due chiefly to the switch to modules in which the functions of several parts or subsystems are not handled by a single complex unit.
Delta Unveils World’s First Anti-Microbial Cooling Tower November 26, 2016 (Roxbury Twp., NJ) Legionella, the bacteria that causes potentially fatal Legionnaire’s Disease, and other strains of deadly pathogens that are hosted by some cooling towers, have been substantially reduced by the development of a unique anti-microbial HDPE material introduced by Delta Cooling Towers (deltacooling.com) on September 1, 2016.
Companies Push the Boundaries of 3D Printing Composites October 26, 2016 Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.
Hard Titanium-Gold Alloy Ideal for Artificial Joints October 5, 2016 Researchers at Rice University (Houston) have discovered a titanium-gold (TiAu3) alloy that is harder than most steels and may be an optimal choice for use in orthopedic joint replacement surgery.
Searching for the Perfect Lightweighting Recipe September 1, 2016 Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.
No Two CFRP Materials Machine Exactly Alike August 31, 2016 Carbon fiber reinforced polymer (CFRP) composite materials deliver the important performance advantages of high strength-to-weight ratio, durability, and extreme corrosion resistance in lightweight structures, valued especially for demanding aerospace and oil and gas industry applications.
3D-Printed Parts Restore Cars’ Glory August 12, 2016 Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.
Honeycomb Heroes: Making Composites for Aerospace June 24, 2016 There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.
Grinding Gamma Titanium Aluminide August 13, 2015 Titanium aluminides possess many characteristics that make them highly attractive for high-temperature structural applications in automotive and aerospace industries. Their high specific strength, high-temperature stability and oxidation resistance relative to conventional titanium and nickel alloys make them beneficial for use in low-pressure turbine blades for aerospace engines, as well as turbochargers and exhaust values in automotive engines.
