Love this style of glass! VERY easy to work with, while delicate, it holds together significantly better than other stuff i have bought. Works great on anything and everything Ive build on my RV8. My go to fabric!!!

Using on RV10 lead fairing. Easy to cut, place, epoxy etc. Got 2 yds more than enough material.

Two layers of this is solid but flexible, I made some naca vents and two layers seems perfect, for an intake I started with two layers and it was more flexible than I wanted so I added two more for a total of four layers and its solid, no flex. I was concerned that with the heavier fabric it wouldnt lay into compound curves very well but it does.

Fills the bill for RV fiberglass work - the right weight and best weave for most tasks. Highly conforming cloth.

Q: My glasair kit came with 50 wide, 9 oz, style 7781 bidirectional fiberglass cloth. Glasair states that the cloth is chemically treated (chemical sizing) for better strength with vinylester resin. Is the fiberglass cloth on your website also chemically treated?

Yes, Hexcel uses an F16 sizing which works with structural epoxy, polyester, and vinyl-ester resins.

Q: Is this bidirectional?

This material is bi-directional.

Q: Does this FIBERGLASS CLOTH 7781-50 ship to customer together with COC? does it have Shelf life limititation?

No, certificate of conformance must be requested at time of checkout, it does not come standard (additional fees may apply).

Finishes on Fiberglass fabrics are generally very stable to environmental conditions. Most fabric/finish combinations, silane and Volan-type finishes included, will not lose significant levels of properties under standard warehouse storage conditions -- <65% relative humidity and between 50 and 120oF. Hexcel believes that Fiberglass fabrics stored under these conditions will retain their full properties for at least two years.

Q: Is this 7781 cloth bidirectional?

Yes, this is Bi-directional

Q: Is this E glass?

Yes, this an e-glass 7781 style
