Nano Resins

Has anyone used newly formulated nano-resins ?

I was kinda reading up on it a tiny bit. Supposedly supposed to make a very strong part. Anyone know where to buy nano addatives in small quanities or is this something a person should just not mess with that becomes airborne for hours or days or is toxic if breathed in or absorbed thru the skin?

We’ll need some university R&D guys on here to talk about it…

Does the nano wiggle the resin into place on it’s own? :cool:

Uh, I guess that means me Werks?
I don’t know much about it. Only one group around here is even dealing with nano particles in resins.
The point is, to add a strong and light weight filler to the resin, which in areas between the tows, where it is resin rich, there isn’t that much mass. It’s like adding cab-o-sil to the resin.
However, there are problems, such as the particles sticking to each other through atomic forces, and causing blobs. Also, the fibers might filter out the particles to all areas during infusion.

Also…nano particles ARE TOXIC. A normal dust mask or even respirator will not be effective. While I’m sure they don’t know exactly what it will do to someone…it can’t be good.
I work with micron and mesh scale powders and need to take special precautions before it gets into a polymer.

Wait till companies start producing it, and buy it from there…it’s still too new.

Nano epoxies are very expensive, I had some quoted last year at $40-$45 dollars a pound depending on the percentage of nano tubes in the resin. Premixed nano epoxy tends to be the best way to get it at this point since it is very difficult to mix properly and dispurse evenly. Prepregs are also availible with nano tubes. At some point in the future I imagine that all high performance resin systems will have nano tubes as a standard once companies come up with a cost effective way of producing and dispursing the nano tubes

Is this what you’re talkin’ about?

Carbon nanotubes http://en.wikipedia.org/wiki/Carbon_nanotube

Yes. Zyvex was the company I was talking to about their nanoepoxies.

I wonder if it makes the laminate more brittle? I’m sure I don’t need this technology for the type of work i’m doing, but who knows maybe some day i’ll do an actuall structural part and have a chance to try that type of nano resin.

stiffness is up, elongation is lowered.

of course you also have the carbon nanotube yarn fabrics. I want to say 3Tex, but I might be wrong. They are Z stitching carbon with nanotube yarn. Or something like that. It’s neat. They grab a nanotree, and the others follow with it due to atomic force, and then they spin the string into yarn.

cool, never knew they make nanotube fabrics, ill have to look in to that. Have you ever used any before?

no, but if it IS 3Tex, I am sure I can get some. It’s prod in early stages of prototyping and testing. I can’t see how it could be mass produced yet, they only started being able to produce large sheets of carbon nanoforests.
