Does fiberglass cloth get old?
The reason I ask is that over the holidays I had the opportunity
to stop in Balsa USA to pick up some supplies. One of the things
I bought was a yard of their .58 oz. glasscloth. When I got home
I found two packages of cloth in the box. One was the yard I ordered
and the second was two yards of cloth with a sticker saying 'free'.
The free stuff is discolored and looks like it sat on a shelf for
a long time or it was hung up in a smokey room.
I plan on using the free stuff for some experiments where if using
it causes problems I'm not to concerned. Just wondering about the
stuff though?

Glass is one of the most durable materials imaginable.
Museums have glassware thats several thousands of years old.
There are houses with windows that are a couple of centuries old.
Glass cloth is made from the same stuff. I'd say the glass cloth
will still be there when the rest of the plane has recycled
itself.

Can't imagine what would cause the cloth to change color Dan, if anything its a environmental hazard in its stability. The only thing I can think of is that the cloth has some sort of coating (sizing) on it to preserve its shape while its in the store. The sizing would then disolve during layup. Try a bit of lacquer thinner, alcohol, and any other solvent that comes to mind on a little piece of it. Just to be sure its not some kind of contamination. How will you know if its contamination and not sizing? Well, as one of the great experts on the subject I can definitely say that contamination is Icky! | |||||

I called my friend Cam and asked him about it. He said the
discoloration is most likely yellowing caused by the ageing of the
stuff they treat the cloth with. He's seen that before and says
it makes no difference to the effectiveness of the cloth. Guess
I got a pretty good deal.
