i need to cure a fuselage half, a wing, a stabilizer to 120ºC efficiently. Should I build three huge ovens all of different sizes out of galvanised iron? The oven should be storable in pieces.
After thinking about it the standard oven solution is not a solution for me.
I have started thing about building a modular insulated tent I can roll for storage.
Anybody has an idea out of what cheap heatresistant fabric I could build it?
Fibreglass insulation may work? You can get that on big rolls. Although it may be a struggle to overlap the rolls well enough to stop the heat escaping.
Where I work we have done a few large post cures with tents made of radiant barrier. These are large tents approximately 140’ long 25’ tall and 15’ wide at the base. We found that we were able to get very stable temperatures (at 105C) with large propane forced air heaters and ducting. The radiant barrier is reflective mylar with a reinforcing scrim. Here is the states were purchased it from Home Depot. If some care is taken the tent can be used multiple times
What temps you want to cure at might dictate your usage of materials for the tent. If you want to cure at say up to 65 C then you might have a lot more choices. Tent size can be a factor too!
Im planning a collapsible tent 6’x6’x6’ using cheap lumber, cheap plastic covering tarp, a staple gun and two 110v electric fanned heaters. That should give me a sustainable 65C for a few hours.
Very nice wing and workshop btw. 
Hmmm, I was focused on stitching rockwool to a fabric but using a radiant barrier seems a much more storable solution and doesnt require the rockwool sandwich stitching nightmare.
Thanks for the valuable tip.
Ideally I will be searching for a cheap radiant barrier that withstands 120ºC.
Can I glue the radiant barrier with silicone? That should withstand the heat.
Here’s a picture of our small tent. This is radiant barrier wrapped around a steel frame. You can see the propane heater. We’ve found it necessary to plumb to gas bottles together to slow the flow rate, otherwise the bottles freeze up. We join the pieces of radiant barrier with a foil tape that seems to work just fine. Not the most energy efficient oven but very easy to put together and store. We have another permanent oven for 5m x 15m for curing smaller parts and making panels. Here’s a shot of the final product a 40m wing that weighs 1000kg
Woow spectacular. Thats definitly the high end of the composite world.
Do a search on Google for Artemis America’s Cup, and you will see some very nice videos.

Impressive! If youre ever looking for a tooling supplier get a hold of me. I just finished a project for a 65m mast for a super yacht that has built in heating for curing a prepreg carbon fiber mast. www.gurit.com/tooling
