I'm constructing some 40ft carbon fiber spars 3in Outer dia. The only autoclave I have access to is 8ft so if I want to use prepreg I need to do it in smaller sections. I'm worried how this would affect load however, so am looking into wet-layup.
Does anyone have tips on how to wet lay-up a carbon-fiber tube this long? My main concern is finding a mandrel and how to suspend it without bending.
