Ehthanol was once viewed as a way to help solve the climate change problem. Then we heard about the huge amounts of enegy used to make ethanol, anad then the effects of crop prices. It turns out there’s another issue–the impact on plastic used under the hood.
A new fuel tank pressure sensor from Robert Bosch GmbH uses BASF’s Ultramid T KR 4355 G7, a partially aromatic polyamide (PA 6/6T) that fulfills a new and crucial requirement for materials used in electronic housings. Any material that comes into contact with modern fuels has to be able to resist not only gasoline but also water and alcohols such as methanol and ethanol. These substances are found in the tank, especially due to the emergence of flex fuels that contain alcohol. The new polyamide (also called nylon) can withstand the presence of zinc chloride. At the underbody area the sensor may come into contact with this zinc salt that can be formed by splash water.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
