Cool! Which CF did you use?
Cool! Which CF did you use?
Sorry what's CF? . for LE and stout: cuben fiber 50g/sqm and for the spinnaker fabrics: maxikote natural MK70P contenter.nixmatters wrote:Cool! Which CF did you use?
CF = Cuben Fiber, now rebranded to DCF = Dyneema Composite Fabrics.
No worries, my French is nowhere near your English!VP22 wrote: ↑Sat Mar 21, 2020 7:04 pmFor LE segment: just insignia tape with french sweing. No problem with cuben fiber possible shrinkage. I can inflate the LE about 0.8: it's very hard and rigid. I think i can inflate with more pressure but it's enough at 0.8.
For personal use it's a pleasure but the kite is less durable for sure. It's not a problem for me because i take care of my kites.
the real problem is the bladder because the all kite fabric finish (with bridles) weight is 0,900Kg and the bladder weight is 0.650Kg. i have find only bladder thickness at 0.10 and it's very very heavy, too heavy. I would like to find some at about 0.5 it will awesome to fly a kite of 9m2 and 1,200Kg.
it's fine to pushing limits with many advice on this forum. If you a conseil for a less thickness blader.
sorry for my english but i don't like to use google translate.
Would you have a link for the PE/PA/EVOH/PA/PE film ? Which valves do you use ?Hansen Design wrote: ↑Sun Mar 22, 2020 12:03 amHello VP22:
Make your bladders out of PE/PA/EVOH/PA/PE film. Half the weight of TPU, heat sealable and strong. Just make sure they fit your tubes and slightly larger. You can also use PE/PA/PE food preservation film. Super light and cheap.
Cheers!
Yeah, where can one buy industrial grade food packiging film? I'll give U-stick a ring to check if their 'orange' valves can be welded or glued to PE film, but if you have a solution, please share, thanks!Hansen Design wrote: ↑Sun Mar 22, 2020 12:03 amHello VP22:

VP22, did you make the trailing edge with Cuben Fiber too? Please report how it holds up after some hours flying and packing/unpacking. I've had negative experience with CF for canopy, therefore my earlier question about shrinkage.VP22 wrote: ↑Sun Mar 22, 2020 10:27 amHansen design: a friend tell me about vacuum sleeve to make a lighter bladder( my actual bladder is 0,1mm because it's a standard one of a 9m2 kite offrench brand GONG for 40€with VAT ).
I'm interest too for a link to find this in and how do you do to heat seal the fabric and valve.
thanks a lot to improve the final result with a possible lighter kite.
Karsten, are you keen on exloring (and offering) a lightweight film ready made bladders for the DIY package?
