Hello everyone,

I have been looking through the forum to answer some basic questions I have but could not found the answer, that's why I am typing all of them here if that is all right. 

1. Differences between 3k, 6k, 9k, and how many different types of fibre cloths are in the market
2. How many kinds of epoxy resins are in the market and their applications
3. Why and how to use Nomex and aluminium honeycomb structures
4. Would it be possible to create parts with polyurethane and wrap them with carbon fibre using the skinning technic?

It would be awesome If any of you could give me a hand with this. Much appreciated
