Post-cure and Autoclave is very different. During post-cure, it's essentially that.

Autoclave is the process when the part in the mold is put under vacuum (vacuum bag) then at the same time while being under vacuum it goes into the oven/room that is sealed and the entire room is heated and pressurized. Essentially the part itself receives double pressure and when heat is also introduced it allows the resin/carbon to flow together on a molecular level becoming one.
Only reason I ask is I've worked in aerospace for a long time. An autoclave to hold a hull is a BIG autoclave an expensive autoclave too. GKN and Boeing have them but I cant imagine anyone else that has one that is bigger than a small mini van.

Funny. I'm a Navy Anviation Engineer so I know exactly what you're saying. An expensive autoclave is an understatement to any performance boat manufacturer to actually have a system that can support the requirements of a REAL autoclave.

But nonetheless, the infusion process that Eliminator, and various other companies are doing, is a great step above the standard "old school" lamination.

So they arent talking about the same thing here right?

Even if boats were a million each (which they arent) its hard to afford one of these...

Outerlimits uses an oven for its cure process but not an Autoclave.

Seems like heated post curing is rare in North America but I thought Outerlimits had one, Greenline Yachts which has a line of hybrid diesels and is built in Slovenia has a full size oven for post curing and a small autoclave for parts. I was with the builder yesterday at a show and he could not grasp that the 39 nortech CC was using traditional lay up methods. He simply could not wrap his head around why this tech is not more common in North America

So what would be the difference in an autoclave and an oven?
