Cellulose Could Replace Short Glass Fibers in Composites
A new thermoplastic composite uses engineered cellulose fiber from trees, such as these logs in Kuopio, Finland, instead of the short glass fibers usually used for reinforcement. Applications include automotive parts and industrial components. (Source: Wikimedia Commons/Okko Pyykkö)
tekochip, that's a good point about flammability. The fact that Ford is working with Weyerhaeuser to develop materials for car interiors, plus the fact that these are engineered, not just natural, fibers, makes me think that potential problem may have already been addressed/compensated for. Here's a link to the MSDS for THRIVE, which gives a rating of 1 (0-4 scale): www.weyerhaeuser.com/pdfs/msds/501.pdf
Hmm, 40% shorter mold times, comparable weight and material properties, less tooling damage during manufacturing, and blendability with a variety of plastic base material. What's not to like about the new THRIVE?
I agree with the flammability issue and the possible overharvesting of dwindling resources. Still, it seems to be a good idea.
Ann, ne thing I like about this product is that it is produced by materials we have naturally here in the US. With materials such as coconut, grow in a fairly narrow band of the planet. This tends to cause overharvesting in areas with low environmental controls.
Ann, this looks like a great use of material. Glass fibers do tend to eat machinery and molds in normal application, so a less abrasive fiber would be great. Has there been any look at using these fibers in nylon applications? Also, is the cost of the additive similar to that of the glass fibers?
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
