Applying carbon fiber veil without dope
« on: March 13, 2016, 09:09:56 AM »
Has anyone found a way to apply and fill carbon fiber veil over solid balsa surfaces without using dope?

Thank you
Mike

Not me as I did one ship in carbon and could see no advantage to it other than it was expensive at the time.   Now it is Poly-Fiber and dope. H^^

Can you outline your Poly-Fiber process, just the substrate part up to ready for the dope color coats ?

I put enough clear dope on the wood until it starts to get a shine to it.  Sanding between every other coat.  Then thin the dope to where it is like water and brush it over the Poly-Span.  On compound curves you may need to use an iron to stretch it s bit.  If you have a wrinkle some time the iron will shrink it, other wise you have to sand it out.   Then it's more dope.

So, what are you talking about, Poly-Fiber or Polyspan?

No. Poly-Fiber is a Stitts product for covering 1/1 scale airplanes. It's a dacron (I believe) fabric.

From their web page.

"Poly-Fiber is the world's best-selling fabric-covering system. For over forty years, the all-vinyl Poly-Fiber system has proven to be the easiest to use, most forgiving, and most durable system on the market. The system is designed for first time users as well as experienced restorers. A complete STC manual, DVD, and hands-on seminars are available to take the mystery out of fabric covering. Poly-Fiber fabric-covering workshops are given in conjunction with the EAA at major air shows throughout the country. Poly-Fiber lasts over 25 years in outdoor storage, does not burn, and can be applied in high humidity and varying temperatures. Poly-Fiber comes with a choice of topcoat paints; choose a classic satin finish with Poly-Tone or a brilliant high gloss with either Aero-Thane polyurethane or Ranthane polyurethane"

Not trying to be a smart ass, just making sure there is no misunderstanding.
