Hi

I am gearing up for hobby project building speed skate boots from carbon fibre epoxy shell.

I have a initial problem acquiring the right bagging material. Since i have plaster mold of foot , i need to find an elastic film tubing to stretch over the foot mold. The carbon only covers base of foot and ankle and i have seen a video on youtube that shows a product similiar to a large "stocking" get vacuum tight against mold and at the toes resin is squeezed in. See Below at 3.37sec into video

Does anyone know where i can find such a product??. By the way i have spend three days google this.

Cheers Rich , look forward to learning.

Not normal vac bag as such, seems very stretchy possibly a clear silicone as they aren't using any release

wouldn't suprise me if its something they have found via trial and error and its not really a composite product as such

Brought back a few memories ,I did a couple of pairs of boots about 20yrs ago for a speed skater. They were mainly Kevlar with a little carbon but that was all hand lay but I only did the bases leaving the Kevlar 5"long an un laminated and they then went off too a guy who did the leather uppers and would sew the uppers to the dry kevlar

Thought that might be the case, thanks

fiberglast dot com, has a newer bagging material, flexi of sorts that allows for a expansion/contraction of the bagging over... I've no experience with it,, but am on the mailer and saw it in the 'new products' section..

Thank Holy

Just be careful using 'stretchy' vacuum bag like strechlon 200 for infusion. It's high elongation properties do make it useful for complex shapes, but it also become a very prone to developing tiny pinholes and you will spend your life looking for the leaks.
