Carbon fibre tent poles Thought experiment #2
Posted: Sun 28 Jun, 2015 1:06 pmA bit of a follow on from my experiments with making the FG wands stronger.
I have all these cheap and LW 25mm aluminium tent pole sections.
Rather than make a mandrel and use it in rotation I thought I could use it as a permanent centre section. One of the problems with using CF over aluminium is the reaction between the CF and epoxy with the aluminium which in my really large pole I countered by wrapping the aluminium in woven FG tape first
That BOPP fibreglass reinforced packing tape I used is very strong and cheap
I thought about using that over the tubing first and then laying up the CF over that
If I go ahead how many layers of CF? Would a single layer of linear sleeve plus a Bi-Axial sleeve be strong enough for normal use to replace 25*3mm steel tube?
