I thought I'd put up a few pics on something I've been working on

I was given this drawing



So made this pattern from tooling block



Then a mould from tooling prepreg



Then made the part and vacced it down



Took 2 hours to get it out of the mould


199grams

Added the base plate, and cut a hole for the inlet (not shown)


375grams

Going to add the inlet tomorrow, and the outlet holes. And it'll be all done!

Impressive stuff.

Could you do something a bit smaller and capable of standing 2 bar pressure?

In short, yes.

But.

I've already had one stress calculated, and it needs to be around 1.5mm thick, if I orientate the plies at 45 degrees, which uses more material.

It's something I've been thinking about, just not sure I want to

I did quite a bit of research and concluded that I needed a 2 piece mould and a bladder. An open box type mould and bonded flange would not do the job.

In the end I've reverted back to welded stainless.

Yes, but a bolted and bonded flange would. It's nothing too difficult, pretty much the same as what I've made here.
Just a fair amount of work.

Looks nice,

Will you carry out a practical pressure / vacuum test of the completed & assembled part?

I have had quite large discrepancies between simulated and actual practical behaviour especially with joined assemblies subjected to N/A depression levels

Not really, time is an issue. I fit stuff like this in when I think I have the time. Or if its fairly simple, I have someone who I sub the work out to.

If you have to make a 2 piece mould...how is that done ?

I presume the join area needs to be totally smooth ?

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

You have 2 options, lose the join on a sharp corner as I have done.

Or make the mould in 2 cures. Shutter the mould down the middle, and make each half in separate cures.
That way the join will meet up perfectly.
