100gm/sqm biaxial NCF glass

Hi all,

Does anyone here know of any company making such a thing? I’m searching for someone who can make 0±30 triaxial NCF with 50gm/sqm in each glass layer, but with a tight weave, not open as a chicken wire mesh! Or biaxial glass with 0/30 layup with 50gm/sqm in each layer, so a total of 100gm/sqm?

Thanks,
N

Maybe they what you are looking for.

Hi Wobcomp,

I know, and have communicated with, almost all big names, Saertex, Vectorply, Formax, Chomarat, Selcom, Saati, etc etc. None have made or have ready availablitiy to make such a low areal weight Glass. I thought that someone here may have experience with some specialist manufacturer regarding such low areal weight NCF.

Thanks,
N

Nash, I use and pay attention to a lot of light weight materials. I’ve never seen such a beast that you are looking for. If you find one though I want to know about it. :slight_smile:

Wyowindworks, I’ll remember that, if found, I’ll ping you.

Selcom can do 150 gr/m2 in biax carbon, and they are testing 125 and 100 grams. Besides that, they have great service and are great people to work with.

However, glass is heavier, and thus less volume. They do make some very nice lightweigh glass biaxials, though.

Also they do have the opportunity to change +/- 45 to +/- 60 if needed. This is a big change on the machine, though, so whenever they change the machine they call around to ask for the need of this material. Developing a relation with such a company pays off when you need special stuff.

Hi Herman,

Thanks for the info on selcom.

I’ve already got a supplier for carbon. The thing I’m searching is Glass. There are area’s where we cannot use Carbon and must use glass. I’m looking for that really paper thin biax in 0/30, or even bonded uid tape (at least 1m width and without stitching) that can be aligned in the laminate as we wish between 50-80gm/sqm. You know the kind of bonding that’s behind the oxeon material? The only other thing that could be useful would be glass/aramid which I could work if the volume/sqm is identical, that could also allow a slightly heavier glass and lighter aramid.

The need is for material that does not make me a Faraday’s cage out of the structure and has reasonable strength in compression, thus glass.

You could try Epo-Faser-Technik GmbH in Willich, Germany. Contact Peter Adeshina. they do make UD’s, in glass and carbon, and I once had a 200 gr biax from them (more than 10 years ago…)

They have been taken over by SGL, but perhaps they still make the stuff, and have it in glass, and lightweight?

As for Selcom, be informed that they recently installed a new machine, specifically for lightweight carbon multiaxials.

Scrim is the only thing that comes to mind with the lowest awt. Maybe something to look into.
