Worst was that the infusion would seem ok then suddenly the bag would burst. I found out the bag was going into the open side of the silicone connector then starting to stretch to try and fill the void under the silicone and would keep stretching until it burst. Not to mention the bag stretching over cut mesh edges and slowly bursting and leaking there during the infusion! Warren, can you tell me the following Do I need carefully choose the vacuum bag to avoid vac bag bridging or the effect of the vac bag is too small and don't have influence on it? The process is vac infusion Is there any difference between using for example Securlon 500 (elongation at break 350 %) and Securlon L 1000 (500 % at break)? I guess if I want to avoid bridging at the same condition Securlon L 1000 will be better. What do you think? Edited 4 Years Ago by BoB_from_jungle

Strechlon 200 bagging film

Try fibreglast

mporta71 - 4 Years Ago

Is that in the uk ?

Big Tee Racing - 4 Years Ago

No, in the US

Does it have to be Strechlon specifically? Easy Composites have a high elongation bagging film that is exactly the same, just a different brand.

Hanaldo - 4 Years Ago

Hanald I can only see two films on the easy comp site , what one are you referring to ? Cheers tony

Big Tee Racing - 4 Years Ago

Oh, apologies, you're correct. Looks like they don't carry it anymore. Didnt notice when it got dropped!

Hanaldo - 4 Years Ago

Yes, unfortunately we haven't carried it for a couple of years now; we dropped it at about the same time as the silicone coated release ply when we moved over the the VB160 and VB200 that we stock...

Rich (Staff) - 4 Years Ago

Ha! Both products I bought about 5m each of, and still have both sitting mostly untouched on the rack... I can understand why they got dropped :)

Hanaldo - 4 Years Ago

Why did you drop it? With a 500% stretchability it seems to be great stuff. There is even a version that appears to be able to withstand oven temperatures. What are the downsides?

Steve Broad - 4 Years Ago

It's not as useful as it promises. If you know how to make a vacuum bag with regular bagging film, then those films are tougher and much easier to work with. Strechlon sticks to epoxy, it punctures.....

Hanaldo - 4 Years Ago

So, no real issues, then :-)

Steve Broad - 4 Years Ago

No not at all, it is a commercial product used by professionals all over the world for a reason. If it was inherently flawed with defects then it would not be. I just found it not very reliable, and....

explorecomposites - 4 Years Ago

Hi! Does anyone can approved that Stretchlon (200, 800 or whatever) works in vacuum infusion? I mean without breaking film or smth like that. Good, reliable result I mean.

BoB_from_jungle - 4 Years Ago

No, it's no good for infusion. Not because it breaks, but because of its stretch. Where the bag needs to stretch into a cavity will slack off and fill with resin as you restore the equilibrium betwee...

Hanaldo - 4 Years Ago

It just wasn't a particularly high seller. as Hanaldo says above, he has had a 5m pack sitting untouched and that's what we largely saw; small quantties but few repeat orders. In addition, we moved.....

BoB_from_jungle - 4 Years Ago

Got very little to do with the film, and everything to do with technique. Softer films can be easier to use, but they are also easier to puncture, so it's a trade off. But you should not have to rely...

Hanaldo - 4 Years Ago

Everything I use, except prepreg, comes from EC. As you say, their bagging material if pretty tough.

Steve Broad - 4 Years Ago

I kinda disagree here as i had way more trouble with leaky bags with rigid films that then like to crease and when you push that crease around it can damage the film. Loved the strechlon 200 but...

SleepingAwake - 4 Years Ago

I am surprised that you have had problems with, I assume, EC vacuum bags. I have given them a fair amount of abuse and the only problem has been very sharp mould edges which are quickly solved with.....

Steve Broad - 4 Years Ago

No wasn't Easycomposites bags Was mostly when working at clients workshops and have seen a couple of weird bags.

SleepingAwake - 4 Years Ago

Yeh EC are great. Super easy, and their pricing is rock solid - even for me in Aus paying the horrendous exchange rate and freight. If I was in Europe, I would get everything from them too.

Hanaldo - 4 Years Ago

I am surprised that there isn't a comparable supply company in the colony..... :-)

Steve Broad - 4 Years Ago

There is no one supplier of everything like EC. I can piece together most things from all over the country, but it's taken a long time to build those networks. Australia is very behind the times wit...

Hanaldo - 4 Years Ago

Yeh personal preference will play a big part in it, everyone has their materials that they like to use. There's advantages and disadvantages to all of them, and no real 'best' solution.

Hanaldo - 4 Years Ago

If you always cover up the edges of the flow media, the bag doesn't seem to be that tough. I never had to do that and didn't have problems at all. And I used the "standard" heavy flow media quite a.....

oekmont - 4 Years Ago

Which bagging film are you using?

mporta71 - 4 Years Ago

Stretchy film is nice sometimes for wet-bagging secondary bonding, repairs or something but the key is not to make it stretch! Getting a good neat well-fit bag with standard film is good practice and...

explorecomposites - 4 Years Ago

Tony, I am in the US but given how little Strechalon 200 weighs I would be willing to ship you some carefully folded in a USPS international box in exchange for talking through some of my vacuum...

Sustainablecatamarandesign - 4 Years Ago

Few issues stand out to me there, the Strechlon being one of them. However, there's sort of a perfect storm of not entirely suitable materials going on that is likely the bigger issue. For one,...

Hanaldo - 4 Years Ago

Thank you Hanaldo, Tearing my hair out looking for a leak is exactly where I've been at for awhile now... Your advice on using an infusion specific resin is spot on, but I'm going to jump on all th...

Sustainablecatamarandesign - 4 Years Ago

Quadaxial is really the same as two layers of biaxial with one layer rotated it just saves you some time. But essentially means you are infusing 8 layers of a relatively heavy uni, which can be...

Hanaldo - 4 Years Ago

Thanks Hanaldo, I think you're right in terms of my issues being an air leak (or maybe even more than one extremely very very small phantom air leak..). Doing this project in Hawai'i has me generally...

Sustainablecatamarandesign - 4 Years Ago

For anyone reading this thread that might be having similar issues I think I might have figured out some of the factors going into my above issue and hypothesize a combination of three things...
