A36 - Arete Supercar Project- Vacuum bagging Nomex honeycomb cores in place.

As we work to stiffen and strengthen the Arete supercar's monocoque chassis a little vacuum bagging was required to hold the cores and laminates in place while the epoxy cured. This video is a compilation of the steps required to do a proper "bagging" of the cores.

When I was building racing yachts for all of six months, the place worked mostly in nomex and carbon and kevlar The bagging method involved first straiking the nomex with a multi bladed diamond tip pizza cutter , the exact reason for this I forget then the laminate would be covered bu a sacrificial cloth called peel ply then a fluffy cloth similar to what you'd find in a cheap quilt then some shade cloth then the vacuum bag. We would use a vacuum cleaner to pull down the bag while we ran around smoothing the the wrinkles out before turning on the pump , the peel ply was to keep the cloth from sticking , the cloth was to soak up excess resin and the shade cloth was to ensure that the whole surface had vacuum . I don't think you need the special tape or vacuum bags unless you're going to use heat cured pre preg laminate. Masking tape and garbage bags or oven bags will do if you're not using an autoclave or oven, as long as they don't dissolve or contaminate the job any old rubbish will do as long as it gets the job done.

If i had the money i would finance this car and have one! I like this man work a lot. Great work sir

You don't need to worry about excess resin getting sucked into the hose. Just use breather cloth. That will absorb any excess resin.

the one show I watched on tv said that the hose was throw away item like the bag was ,, but they also had sponsors paying for everything ..it did not come out of there pocket ,

This project has been so amazing to watch. I’ve watched every single episode so far. Well done

We should start a preferred followers club for those dedicated souls such as yourself.

Thanks for going to the trouble of posting this video series. It's invaluable to anyone even mildly interested in the proper execution of composites.

Thanks for going to the trouble of watching! I'm glad your finding value in the content. Although I love exotic cars, one needs one, like they need a hole in the head, but it does create an interesting avenue to show composite techniques without descending into boring How-tos.

A good idea when vacuum bagging, especially honeycomb is to attach the vacuum connection beside the honeycomb. People instinctively put it on top. This can often lead to an indentation in the honeycomb and radial bag Marks. If you extent the gagging slightly you can put the connection beside the honeycomb and control the supply of vacuum better!

Barely had room for the tape at the edge of the bag before the flanges, but it would have been nice to offset it.

Very nice 👍🏽

Curious why the reinforcements are being added with the parts out of the mold, instead of adding them while the parts were still in the mold, where the mold acts as a jig to keep them in the exact position the plug was. Are you worried about the parts warping at all doing it this way, especially with the pull of vacuum being used?

[@BuilderCreator]

You will see the parts go back in the molds for reinforcement in most videos, the vacuum in this video was very low, just enough to hold the core in place as it was on a vertical surface.

What is the tool you use to cut teh glass sheeting? Looks like a miniature metal shear, but i cant find anything like it online.

[@BuilderCreator]

Search "electric scissors" I've seen them on Amazon and other retailers.

[@ScottDagg]

Why fiberglass over carbon fiber?

[@coconut5790]

I can't speak for BuilderCreator, but my assumption is that it's because the S-glass produces a tremendously strong product for a fraction of the cost, so it was more appropriate given the budget.

[@ScaniaFung]

y use Nomex core in that part?

[@BuilderCreator]

That part is kind of hanging out to flap in the wind, need to stiffen it up.

Check out "Throttle Stop Garage". He's got great videos on vacuum bagging.
