Skid plate install

My guess would be that a $3500 carbon/kevlar skid plate IS absolutely cured in an autoclave. Also, you don't 'have to' vacuum bag additional wear layers, but why wouldn't you? Lighter weight with better adhesion if you do.

Yes a $3500 skid plate SHOULD be autoclaved but unless it's from prodrive or Ralliart, I doubt it is.

I WOULD vacum bag it but only cause I've got enough bagging, breather and release ply to build an ENZO. But to the OP, with good prep and careful use of resin he can add layers beetween rallies for minimal cost and keep it useful for a long time.

EDITED TO REMOVE CONFUSION

Well, its not like the business that made it couldnt have sent them out to an autoclave to be run. Prodrive, M sport, and ralliart most likely have in house autoclaves, the other manufacturers could just lay it up, vacuum it themselves, and then send it off to the autoclave. Way more economical, if you're not always running composite parts.

OR, just have a place build it for then, like Boeing/the other clients do at Danner. (See link below, click to "our customers"

How come everytime you open your mouth, stupid comes out. It's glaringly obvious you have no clue what you're talking about but yet you feel the need to post anyhow.Send it out to the autoclave? Post up a link to this multi-million dollar autoclave where we can send our parts to, you know, to keep it economical.Also let me know how to vacum bag a part and rush it to this mythical autoclave before the resin cures. Actually better question: Do you know what an autoclave actually does?

Maintenance tech was the title I made for my job, helping install autoclave 2. It was a summer job working with my Dad, at the family owned Aerospace plant. So yeah. I might have a little bit of experience with autoclaves... seeing as I've been around them for awhile.

Economical for you?? No. Economical for a small business? Possibly.

I wouldn't judge until you meet me.

And as for the vacuum bag question, you would use prepreg, not wet layup. That's what my experience is. The expensive, aerospace grade stuff that's used to build pieces for the airplanes you fly in, and the rockets that send things into space.


Would you like to assume anything else?

EDIT::: Saw a mistake, potentially leading to your kind words. I'll go fix it now. I never meant to suggest HE could send it out, just that small businesses making batches could.

There are so many ways to build good parts in composites that do not cost that much. Yes a part baked in a pressurized autoclave while getting bagged using a prepeg cloth to keep the resin to fiber ratio perfect is going to be better then something I build in my garage on a Sunday afternoon, but not that much better...

I expect at the end of the day I would not be able to measure a time difference over a 5 mile long stage between having my home built composite parts vs a full on aerospace built set of parts in a typical North American Rally Car.

In the long run reality always wins.

Hell, by that standard, I doubt you'd be able to measure the difference vs. aluminum.

Yeah I've been around them your entire life.

I am a small business and I make composites. So where do I send these parts to be autoclaved. (actually that IS just a jab at you since I could bring them to work to be autoclaved if I really wanted too.)

Yeah cause skidplates ARE rocket science.

Nobody in North America is making "batches" for fucking Rally cars.

Me too.

Interesting you say you make composites, though. I was actually talking to JVL today and asked if he knew what you did. He said you were a specialty nurse, and recently started a prep shop, not a composites manufacturing business.


Not sure what to believe, anymore.

Jab at me all you want, if that makes you happy, good.

I never said I was a composite manufacturing business. I said I am a SMALL BUSINESS and I have made and make composites when required. Yes I am a Critical Care Nurse AND I own a shop. Imagine that, I got two things done in a just a single lifetime. What the fuck have you done?

You're embarassing.

So do you mean the sterilizing autoclave at the hospital? (which I REALLY doubt would let composites in)

Or do you as a small business have the "multi-million dollar autoclave" to use?


Why do you have a problem with me? Would you like to inform me what I've done?

Yes the hospital uses massive autoclaves.

The whole fucking point is that the OP is working with a FREE skidplate. I doubt he's in the market for your vast autoclaving resources.

It's not some much what you've done it's what you have not done.

Ok. So we're talking about his free skidplate. That may or may not have been autoclaved, but for 3,500 dollars, it could have been. I don't know. None of us know for sure, although, how it frayed, it may not have been. I've seen wet lay up fray from abrasion like that, but I havent seen anything I know to be prepreg and autoclaved abrasied, so it may or may not fray like that, However...


Why are you attacking me? Did you read my edited post? I did not mean to come across as telling him to autoclave it. I even fixed it to explain what I was trying to say better.

If you had taken the extra minute to stop fuming, comprehend what I had written, the second time, I acknowledge I made a mistake, then you should be able to see that I wasn't even referring to what HE should do. Just the nature of how a lot of shops work. Machine, Aerospace, Sheet Metal Fab... I've actually got a lot of experience in them, even though I'm 20. That's what I did for jobs, not grocery stores. I was a shop gopher and learned a lot like that before I got good at sheet metal fab, and did that as a job.

For Christ sake, why is it that people your age take everything as an attack at YOU?

I like composite parts. I also realize that most here like to keep things simple and low cost where possible. So the OP obviously has mad fab skills yo' but probably isn't in the market for $3500 skid plates. BUT he has one now and I was trying to point out how cheaply he can keep keep it alive with some simple wet lay up. If he was closer I'd vacum the parts for him.

Look man, I'll I'm trying to get across is I wasnt trying to tell him to go spend money on autoclaving it, or even vacuum bagging it.

You're right, wet laying up right on top is fine. Its what Danner recomended to me when I was going to lay up my own kevler plate. I asked if it would be fine, because the base was autoclaved. They said "yeah, sure, just make sure you epoxy the frays from the abrasion." Wet layup is excellent for patching the wear.


My whole point was never that he should do that, it was stating that for 3,500 dollars, its very likely more went into that plate then just a simple mold and wet layup. I was never even giving advice about what he should do, that was answered, and others were talking about the price of it, and I was saying how it could be justified.
