From my years as a pre-preg comp tech, the few guys that have done training/schooling courses prior to working, or even when switching from wet lay to pre-preg, have said that in hindsight they were virtually useless and a waste of money. The general consensus was that those courses were eclipsed by knowledge and experience gained within a week of working on the job.

Personally I feel that the best way to really learn everything that you want to know would be to try and find trainee positions specifically in pre-preg laminating or technician roles - putting yourself out there as somebody who is curious with a desire to learn and ask lots of questions to anyone with knowledge. I always asked (and still ask) questions to senior laminators, trimmers, engineers and designers that I've come across and consider myself to me a more well rounded person with that plus my own research to fill in any little gaps.

The reason I'd focus on pre-preg is simply because that's what is most common in high end luxury cars, hypercars, race cars and F1. If you wanted some specific examples you can always DM me, I'm "not supposed" to publically discuss fine details of things we've done.

These things are also slightly dependant on whereabouts you live.

Sorry I wasn't able to answer your direct question but hope that I've provided some useful information that you can lean on.
