Defunct Carbon Nanotube thread?

Hi,

I posted a new thread a few days ago regarding the use of Carbon nanotube enhanced epoxy in my small structural parts project.

I can see that Matt from the staff has answered, but when trying to access the thread, I keep getting a "404" error ?

I have since then had very positive replies from the NanoCyl people, and they are now helping me along Smile

I still have a tech question though.. My first tests indicate that your infusion epoxy is the best for my small parts, the prototypes used for strenght testing are very close to the goal, but the Epocyl additive may bribg me the few ten of percent more strenght that I need.

The question is: What type of Epoxy is the Infusion grade EC epoxy?  Is it Bisphenol-A based or "tetrafunctional" ?

This has a bearing on what precise type of additive I need to get from NanoCyl.

I will of course be posting my results in the forum, in due time ...

Cheers ..

Yes, my plan is to make a few simple geometric "lay-ups" one set using Epocyl enhanced resin, and one using standard EL2

Both sets will be made in "compression" molds made on my lathe, in hard alloy aluminium.  The parts will be cured and post-cured int the molds.

First sets will be "test samples" which will be tested to destruction in a  hydraulic press, using a 1000 Kg load cell.

I will simply take the "bar-shaped" test sample and load it up in the press, with a couple of micrometer dials mounted to see the stiffness of the material.

I will be very happy if the Epocyl enhanced part shows just a 15 to 30% increase in strenght and stiffness.

watch this thread later .... BigGrin
