This part wasn't infused, it was laminated wet, then placed under a vacuum to clamp it in place and remove excess resin from the part. Generally I prefer infusion for a number of reasons but wet layup vacuum bagging works when you need to clamp the laminate in place against the mold and helps increase the fiber to resin ratio, which will improve the mechanical properties of the laminate.

If you're referring to the tape around the edges of the top layer of carbon it was put on there to help keep from distorting the weave while handling the carbon. It is outside the finished area and was cut off later.

If I was trying to fabricate a carbon foam core tube 19 inches in diameter and about 14 inches deep. ...could this be bagged? Would you think going around the outside or inside of a mold would be easier. I'm thinking that inside would be best if it can be done at all. .also. ..would the release agent work on vinal? Thanks and I love the video. ..makes it look to easy!

We used chemlease 70-90 semi permanent mold release on this, a paste wax such as meguiars 88, TR-High Temp, or Honey Wax would also work.

nice video! Question about the vacuum connector, is it a normal Orion or euro connector you use? and if you disconnect it, will it keeps it vacuum?

how long time with vacuum, nice proyect, thanks

i would have liked to see the end product

@skylergreenhaw We let it cure overnight but with the Resin Research Fast at room temp it is usually pretty hard in 3 or 4 hours. I just posted the videos of de-molding the panel, the video came out a little fuzzy so I'll try to find some better pictures of the finished panel.

Is that vinyl tape on the mirror around the laminate to help contain the resin?

Nice video, how long did it take to cure? Are you going to show the finished product?

Is that a wax/mold release that you guys brushed onto the glass panel before laying the CF on top?

What's your fibre layout angles? How many plies did you guy used for this? Is it just a 0/90/core/90/0?

why bucket and brush then infuse??

Why the wet layup? Is it possible to infuse with vacuum when using a foam core?

Hi, hoped someone could help me out,... . I need an epoxy or any type of resin that hardens at room conditions, but that I can reheat to press in shape (after fully cured). Does anyone have an idea for what kind of resin I should be looking into? Or maybe a product name or manufacturer? Thanks in advance.

hi, Do you know any other kind of sealer that i can use instead of the sealant tape because i cant find it in my country and cant buy it online

Use duct tape

and honeycomb core? same process?

ie the bright green tape

honeycomb will soak the resin, which is what you dont want. i would make one sheet, or layer of carbon, with peel ply then let it dry, rip off the peel ply, give the surfice some new resin.. if you want extra strong stickness to the carbon layer, you can thicken the resin with cotton. then lay on the comb, and on top a pre weted carbon fiber.. do not lay a dry carbon fiber on top an wet it with a brush, cause this would cause the resin to fill the combs

Did you put any pleates into the vacuum bag?

***** If there were an edge face, I'd say some pleating would help.

that's what i'm thinking, that's the reason for vac bagging, if you wet layup just put two more layers and sand .

just the fact youre using Bag Tape eludes to the fact you're using a Vacuum Infusion Process, and not just vacuum bagging.

the vacuum pulls out the resin - they did it just the right way.. final part will not have any grams too much resin.

How can you find out how many layers of fiber to use for a part?

Take a college level course on structural composites...OR... if its for looks only like 99% of the stuff you see on cars etc.... trial and error. No one can answer the question unless you have a specific product or part in mind.

usually 4 layers of 5 ounce carbon fiber cloth vacuum bagged yield about 1 mm thickness. 2.5 mm is perfect for most applications when you get into 16 layers at 4mm thickness parts get heavy and its better to use aluminum or alt materials

No gel coat? no precise resin amounts? One sheet on either side? was this just to show students or something?

@@FiberglassSupply ill be wet laying 5 layers total. 3 carbon, 1 lantor soric and 1 kevlar. would I still need the perforated film, or could I with just do with the absorbent breather cloth? If I dont have the last breather cloth, could I use a susbsitute? I do have the peel ply and also have a resin flow mesh, cause I was gonna do infusion but the mould had a small leak somewhere, so now ill be envelope bagging the whole piece. The other option I was thinking, was to wet lay the cosmetic laminate cause it cant have any flaws, and then once it tacks, add the other layers , and infuse the final layers. Looking forward to your response, thx.

If you are going to wet lay I would highly recommend using the perforated film. For breather you can use a number of things, burlap, bubble wrap, flow media, quilt batting, etc. Breather fabric tends to work the best and is generally less expensive but those other options can work too. With wet layup vacuum bagging you want to back you pressure down to 10-15 in hg. Just enough to hold everything in place and consolidate the laminate, too much pressure and you’ll squeeze too much resin into the breather and get a porous laminate ( which is why the perf film is important). Personally I would still consider infusion using the envelope bag over doing wet layup vacuum bagging. You can send me pictures of the mold/part to matthew@fiberglasssupply.com and I can give you more specific advise.

@@FiberglassSupply ok. I was also thinking about doing the very first or cosmetic layer by wetting it, and then the rest by infusion. Is that possible? As farcas the mould, ill be spraying a uv clear prior to applying the resin and first layer of carbon.

@FiberglassSupply

That is possible too. The uv clear should also help seal up the mold.

pre-preg or go home.

waaayyyy!!! to much resin the strength isn't in having a bunch of resin the strength is in the fiber. the resin provides stifness to hold the desired shape but to much will make your part brittle and it will definately crack!! Obviousy since this video was made a year ago you've gotten more experienced perhaps it's time for an update.

Way way way too much resin.
