Composite to line Stainless Steel Box

Composite to line Stainless Steel Box

Composite to line Stainless Steel Box

(OP)
I have a "box", basically, that is going to be made of Stainless Steel, that has water pumped through it to cool the internal components. The requirements are it needs to sustain our operating temperature of 150-200 F without deforming, and have a dielectric strength that can handle 2,000 V. As I currently have it designed, the wall thickness for this composite would be about ~1.5 mm. It should also be machinable, so that I can put an O-Ring groove in it where necessary, so possibly a durometer of about 85. I need to make sure the water does not see the steel, though, or else this will not work, so it will need to bond well to the stainless (I can rough the surface of the stainless to increase the bond if needed).

Does anyone have any suggestions for this?

I was thinking I could make a "brick", basically, attach it to the threaded holes on top, and pour the resin/epoxy/composite around it, have it solidify, then remove the brick. I'm not sure how easy this can be done, though.

I'm attaching a pdf of what I am envisioning here.

Thanks
Bill
