Tygaboys Carbon Fiber Fabrication Seminar Episode 3

[NONAMEWTF]

yeah, that seems to be a pretty good idea but the carbon part will be a bit more less than the original part or not? in some cases it won't fit anymore or am I wrong?

[TheSalzar]

Have you tried google?

[BMWTechnician]

Where can I get these giant sheets of carbon fiber so that I can make my own projects?

[Rayevo888]

what i concert is ... what u find the mole thing ... and the ""ｏｖｅｎ　＂＂to melt your carbon fiber

[TheBakachan]

A really good source I was directed to is US Composites, they sell online too. They have CF, Fiberglass, and Kevlar. They even have Kevlar/CF hybrid weaves. Nifty stuff.

[sudicalwig]

We do various other processes like RTM (resin transfer moulding) where you'd have a two part mould that you close and add vacuum to. Then you inject the resin through tubes using a pump, overfilling it. Then reversing the pressure and let it cure. using this method and two sided moulds, you can get a nice gloss looking finish on both sides which is great.

[sudicalwig]

I work with composites but we use "closed" processes instead of wet laminating. I would prepare the mould, lay up the dry fiber and bag this. Attach tubes and infuse the resin using the vacuum suction in the bag.

[Fastlife70s]

Good info! Do you get any special kind of bag, or any specific tool to do that?? Where can I get those tools? Where can I find more info about it? Thanx.

[sudicalwig]

There are a lot of clips on youtube showing how vacuum infusion works if that's what you mean. Again, it's really about what kind of results you want. For some jobs the process here works just fine.

[Fastlife70s]

Thanx, but I was talking about the RTM process. How do you do that? Is there any special kind of bags needed?? Seems that its a very precise way to get the ratio you need.

[sudicalwig]

No bags. A two sided mould where dry fiber is layed up. Then the mould is closed and resin is injected into the fibrepack using a pump that also mixes the two resin components. I wouldn't say that this would be suitable for a "one part" job since you would have to make the mould from reinforced composite materials or say aluminium. But for large series and cycles it's great. It's a closed, clean process.

[mattamiller]

I want to make just a carbon fiber inlay. Can anyone tell me how thinnest carbon fiber can go 1/8th inch? 1/16th?

Thanks

[tbclrk6]

so what exactly did you use to seal the edges of the back? what type of tape or w/e?

[NoOtherNameWasLeft]

It's yellow vaccum bagging tape. It's like a putty. You can search for vaccum bagging supplies or try the fibreglast site.

[cocy3000]

hey! great videos... i wanna ask u something... i rely wanna know if epoxy resin its the same resin u need when u have to "bake" the peace to add hardness... the thing is that i wanna make some diamondwood and carbon fiber fretboards and necks for guitars and basses... i heard something about phenolic resin but ur de expert :D

thnx

[NoOtherNameWasLeft]

Wow! Cool project!! Way our of my league though. Maybe one of the other viewers has the answer?

[cocy3000]

well thnx any way, im a lilte confused with the resins bwcause there is a bisphenol F epoxy but im not shure if its the same thing as phenolic resin, because i havent seen any were that "phenolic resin" for sale just the epoxies... i all so saw in a web page something about heating epoxy for more resistance and hardness that sounds interesting... resins are very insteresting materials, u can do wat ever u want with them...

[beachnative420]

By heating certain epoxies you raise the shore hardness.

[gtrs1983]

what brand is the vaccum pump and where can i find one

[NoOtherNameWasLeft]

Hmm, I don't know the brand. He probably got it used or bought it from fibreglast online.

[vacuumformer]

You can use any decent vacuum pump for vacuum bagging, or a converted oilless piston air compressor. (You just need to enclose the air intake and attach a fitting to it, if it doesn't already have one.)

You can even use a bike pump; it takes about 20 minutes to convert it for sucking, for total cost of less than $20.

There are how-to's about doing those things over on Instructables. (They're also linked from my web site, which is linked from my profile here.)

(BTW, nice video series!)

[afie83]

how do we make large hole somewhere in the middle of the project? should we drill/cut after or before the project is cured/dried? Thx.. (pls hit my 'reply' button to reply)

[NoOtherNameWasLeft]

You can drill & sand after the part cures.

[exonei]

wow that kid's hair is really red

[lethaly3]

Is carbon fiber not supposed to be baked or is that for some other method ?

and this resin, is it the same resin as you use for fiberglass ?

really curious about theese things, are theese methods just for smallparts or could i do bigger parts this way ?

[buynowfourless]

Did the inside of my mold came out pretty good but kinda looked like "dry carbon" any ideas for the glossy carbon look? Clear coat?

[NoOtherNameWasLeft]

We were told to polish the "plug" (the part used to make the mold) or to polish the mold.

[NoOtherNameWasLeft]

Yeah, I didn't believe peel ply wouldn't stick, but the stuff works.

buynowfourless: you can mold off the back of the part sometimes. We tried in the vid & just made sure the back was shiny.

[buynowfourless]

Nope just did it but I did the carbon on the outside of the part i was molding and the peel-ply made the outside of my part dull so I guess I gotta try and mold the inside of the part

[grov05]

doesnt that shit stick to the vaccum bag? sounds like it would stick

[buynowfourless]

Do you turn the pump off and just leave it over night? Thanks

[NoOtherNameWasLeft]

Tygaboy said that the bag is sealed and once you pull out the air, you can shut it off--just keep checking that it doesn't lose all its pressure.

[buynowfourless]

So how much time do you have between wet epoxy and vacuum bagging? Right away while fully wet?

[NoOtherNameWasLeft]

Yup, it was fully wet.
