Getting ready to lay up a new canopy.

Debating to use either carbon or glass.

Advantage of the carbon it may be a bit more protection in the event of an accident and the weave is also pretty nice to view.

Disadvantage is that it will be black, I could paint sections of it, and I'm wondering if it may act as a Rf sheild ??

Glass is a bit easier to work with, won't be a strong, and will require a full paint unless I pigment the resin.

Thinking of the carbon route. Opinion's ??

Hi Greyeagle:

If you think about it, the only real difference comes down to personal taste and asthetics.

Fiberglass is relatively inexpensive and is definitely strong when laid up with two or three layers at 45 degree angles (that, plus thickness). You will definitely need to paint it to make it look good.

The only real reason to layup a canopy in carbon fiber is strictly the cool-factor, 'cause they just look good. But are your skills up to the task and do you have the right tools to do it properly? (vacuum bagging comes to mind). It will be more expensive than fiberglass and it will get hot in the sun. Also, there is no advantage from an RF shielding standpoint because it doesn't fully wrap around your radio or engine, and it's not electrically grounded.

I guess you could lay one up in fiberglass and see how it turns out, then lay it up in carbon fiber if the results are good. Just some stuff to think about. . .

yes carbon can act as RF Shield. if you are using a deans antenna do not put it inside the carbon canopy it may affect the effective range of the signal.

Brain fart. . .

I was thinking of the windscreen only, not the entire canopy. Although there isn't any hard data supporting a base-loaded antenna inside a carbon fiber canopy, I would be cautious about doing so without some testing first.

Do to the war, carbon fiber is very costly.

Russia has been using basalt
fabric for years in their space
and missile programs

Basalt fiber is inorganic compound and is non-carcinogenic unlike carbon fiber.

What if you went to a thinner glass and reinforced the high stress areas with strips or rings of carbon, maybe on the inside? I don’t believe the carbon is going to shield RF. If it did everyone that is flying carbon structured birds would be in deep do do when the frame is in between the receiver antenna and the transmitter.
