Nice article, Ann. This sounds positive all the way around. With cycle times 40 percent shorter, there are probably some cost savings. Does the material itself also offer some cost savings.

TJ, since this is a composite, the fibers are surrounded by a polymer matrix (polypropylene at this point in time), so I doubt if water absorption is a problem.

What happens to these composites in the presence of water?  Glas fibers do not absorb water; is that a problem with this new material?

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

Tim, no info on fiber cost was given, but considering Weyerhauser's main business--wood pulp--I'd guess it's likely to be less than glass. Re "use in nylon applications," what exactly do you mean?

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.

One attribute not mentioned in the article is flammability, which is something cellulose products have always had an issue with.

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?

No, we're not having delusions of grandeur -- this is the weapon of a Jedi Knight. And we're dying to see how it works. Today, we tear down a lightsaber.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
Fully adopting multiphysics simulation software enables companies to optimize cable and systems designs for a wide range of harsh environments.
