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?
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
