Fiberglass Sheets

[GregSilver]

Not sure where to post this...

I am looking for Fiberglass sheets 1/16"-1/8" (Ideally 3/32") for structural frames for a quad-copter and/or various other parts like side frames for small heli, motor mounts for small planes, etc.

Would something like Electrical-Grade Fiberglass (GPO3) would well for this?

Is there something more commonly used? I am trying to stay away from carbon fiber, as the price is just way too high.

I have only found the GPO3 at McMaster

If I was going to try something else it would be G10-FR4. You can get closer to some of the specs with it. However, nothing is going to come close to carbon fibers "Modulus of Elasticity in Flex" spec.

Here's specs off some tech sheets I found for the 3 materials.

Tensile Strength (PSI)

GP03: 10,000

G10: 40,000

CF: 65,000



Sheer Strength (PSI)

GP03: 14,000

G10: 19,000

CF: 12,500


Flexural Modules (PSI)

GP03: 1,230,000

G10: 2,700,000

CF: 18,600,000

Interesting. Carbon fiber is just ridiculous in price. Is there any place cheaper than mcmaster for it? The other thing about cf is the rf interference with it.

GPO-3 is glass Polyester . The colour is white or red , Not used in R/C .
