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?

       

Would say this is prepreg but this could be a "self made" prepreg as well.
By this I mean they wetted out a piece of carbonfiber with resin and placed it in the mould, then bagged.
If you want to be sure, put your part for 1h at around 100°C in an oven and see what happens, If it's not prepreg it will have a big impact on the finish and will be very flexible at those temperatures.
If it's prepreg it will more or less stay the same but there is a small chance the clearcoat or topcoat will have some effect. 
That's how I would try to figure out if it's real prepreg or not, as I assume they won't be using a high temp resin if it's just bagged.
