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?

       

Thanks for the reply. I am concerned about the bubbling and the overall weight. Also prepreg was considerably more expensive than wet infusion. So I want to know I am getting what I paid for.

Have you seen this type of bubbling on prepreg parts?
