    Re: High Temp Resin Recommendations

    My original plan was two metal pipes of 4" diameter. I might still go that way if the right material drops in my lap, but the I still need to spin a pair of inlet tulips. By the time I do that I could have made a simple plug and popped out the oval duct in composite (I think).

    Re: High Temp Resin Recommendations

    Has Jon Sharp retired yet? If I recall correctly he and some of the Nemesis team members were in the composite materials engineering division of an aerospace company. If you can reach Jon he would certainly be able to give you, or get for you, a recommendation for an epoxy resin that would have XYZ temperature capability.

    Ralph Wise would also possibly either know of some particular resin form his experiments, or I would bet he can pick up a phone and get a recommendation.

    Jon hasn't been around these parts for years now. Last I heard he was out of aviation to care for family out of state.

    I have one half of the duct curing with RT epoxy now. I'm going to try it as is and see what happens. Worst case, it fails and l build a new one out of HT resin. NBD.

    Re: High Temp Resin Recommendations

    Since NOMEX is used as a fire barrier, I wonder what resin is used in conjunction with it?

    Got the other half off the plug and clamped together for a trial fit.



    Just to be clear, the pipes will be brought together in operation. Working on the plug for the inlet belmouth.

    Re: High Temp Resin Recommendations

    I recently made a new carbon fibre sump to replace my heavy steel one by using this resin :EPIKOTE™ Resin MGS™ RIMR 935 and
    EPIKURE™ Curing Agent MGS™ RIMH 936/937.
    It's made by Hexion which I belive is available in the U. S.
    I like it, not too viscous and has an HDT of 130 deg. Celcius or 270 deg. F. I cured it in the kitchen oven for a few hours ramping up slowly. Even at 130 deg it still retains its shape well.
