this looks like an interesting development, Ann. I had no idea the US Nancy was in the composite research business.

Impressive details on an advanced subject matter

Ann-very informative article.  Kudos to your level of intellect and experience in this very technical arena of advanced material sciences. I knew that you were a materials person, but you've just raised your own bar! You've delved into materials processing topics I have absolutely zero knowledge of, including resin infusion molding (RIM) and resin transfer molding (RTM).  

Regarding the physical properties descriptions of this stuff  --- (Phthalonitrile – did I pronounce that correctly-? ) --- thermal and water-absorption resistance, coupled with its strength are impressive.  Thanks for opening this door for me; looking forward to learning more.

Rob, I discovered the US Navy's research when I was looking into "nautical" robots. One of the robotic jellyfish we wrote about, RoboJelly, as well as its big brother Cyrus, are projects funded by the Office of Naval Research. The NRL is only one entity involved in various types of research, and it also serves the Marines.

Wow, thanks, Jim. I wasn't sure if readers wanted something this technical, but many discussions like this one just don't reduce down. RTM and RIM are standard processes that have been around awhile but not for high-performance materials like this one.

ON the issue of technical writing, DN has consistently evidenced that the deeper a technical issue is, the lesser the comments.  (Case in point; this article).  But I think that should be expected; -- for example, there have been several other deep articles from Guest Bloggers that I couldn't begin to comment on. The interested field of commenters just naturally narrows.

ON the subject of RIM, I was [minimally] familiar with another industrial process – Reaction Injection Molding (a different RIM) which is [loosely translated as] an injection of a 2-part epoxy.  A very slow processing time because 'cure' is required.  Checking my old faithful resource, Wikipedia doesn't have a page for your definition of RIM but does link it to your other suggested process, Resin Transfer (RTM). 

Always interesting to learn about new things – Thanks!

Ann, while I don't have a use for this information today, it is certainly handy to have. This source of knowledge is a resource, and like most resources becomes reallyn valuable wnen you need it, and only "interesting" the rest of the time. I can see an immediate application of this material in high frequency hiher power RF electrical applications. 

What was not mentioned about the new material was outgassing, which affects the usefulness of a material for satellite and space applications, and also for semiconductor fabrication applications. 

So thatks for the educational article.

Can you share the contact at NRL for this?  I work for the Army and we have some possible applications.

William, you're welcome. What you see here is what we were allowed to know. I understand from the source that NASA is very interested in this material, but I wasn't allowed to find out for what.

Crash55, the contact is the person interviewed in the article. I reached him through the PR contact on the USNRL press release.

Thanks. I missed the name the first time I read through it. I should be able to find him in one of the DoD directories.
