Looking to coat a spiral wound cardboard tube 142mm OD with 2mm wall 2m tall. it will just add more strength to the tube, it needs to be light yet strong. It also needs to have a good finish, may or may not be painted. What do I cover it with? Sleeve, woven cloth, fibreglass, carbon, Kevlar???? Peelply or vac bagging?? the tube is hollow and needs to keep its shape as parts fit in and slide out to allow recovery. There are also 3 large fins at the base, so do I do tube first, then cut slots and slide over fins then fillet the joints or do i do in 1 hit and hope it looks ok. Depending on motors it could be going up to 650mph in a few seconds to about 10,000 feet, also has to take landing on parachute. I know a lot to take in just asking. Thanks Colin Tags rocket sleeve tube

Used peelply on a project a while ago when vac bagging a part, came off ok. what males you think its will not come off (thought it was designed to peel off) Also the nosecone is already made (polypropylene) do you think thats going to be hard to cover to make it neat or should i just paint it?

RE the nosecone, covering polypropylene will always be difficult because nothing (including paint!) will stick to it! Matt Statham Easy Composites / Carbon Mods - Technical Sales
