Resins for combat props
« on: June 26, 2021, 12:58:51 PM »
A while back I saw some props that were from overseas that were simple construction have several strips of carbon fiber tow and the rest poured resin. They weren't as stiff as full carbon props but they were stiff enough. I thought they were cast with either vinyl ester resin or high strength polyester resin. I know large wind turbine blades are done with high strength polyester, it is tuff stuff. Anyone know about these props and were they made with the vinyl ester resin or high strength polyester resin?

Dear Dennis,
our Hungarian Combat team is technically very-very close to Ukrainian team, all the technical resources are common between them, but ours -as they are native Hungarians, and all have double nationality- are competing under Hungarian flag/colors. As I have seen, they use mostly glassfibres, exclusively in epoxy resin. Not for the cheaper price of glass, but not so rigid as the carbon. And the weight does not matter by Combat.
Shall I connect you with them, in a PM?
Are you maintain your eventual Hungarian roots and connections? I am asking after your family name...
Regards: Istvan Travnik (some times TM of Hungarians at a WCh or EChs... )

As Istvan said, they are not just clear resin.
They are well filled with glass, that when properly wetted out becomes quite clear.

MM,
Who sell this in small amounts and what cure agent do you use?

For 1/2A has anyone tested some of the Urethane resins? There are some that are ridged and suppose to have high tensile strength. Not as strong as Epon but could be close enough for single use props.
