I had these parts made for a project I am working on and the manufacturer claims they are 'autoclave dry carbon', which should mean pre-preg, but to my untrained eye it looks like regular vacuum bagged wet infusion. There are tiny bubbles along the edges and the outer clear resin layer seems thicker than what I would expect a pre-preg.

Are there any carbon experts out there that can help me identify what process they used to make these parts?

       

Agreed with Oek. You’d see the flow media marks on the back if it was resin infusion.

You can see the release film marks on the back surface from traditional bagging with breather cloth. Looks like a very resin rich prepreg layup that either bridged on the fine edges and/or had resin pooling in the corners.
