HI everybody,
I'm trying to get some quote about the Epoxy resine and the Roving fabric needed for the building of the boat.
There is this company in Poland, called www.c-l.eu, most likely the one Janusz/Piotr get is stuff from.
So my question is the following one:
What sort of Roving fabric do i need? plain or twill ?or maybe triaxial, biaxial?
I could not found any specification in the boat's plans-documentaion.
Would you recommanded to use different type of roving fabric so each type would created a more complex hull structure. (i did read the blog post from MarineMArtrell, www.martellmarine.co.nz/blog/cg580-okoume-test-panels-fibreglass)
Or only use the same roving fabric type for the entire hull?

ALso I have a question about the right hardener to use with the booth resin Janusz propose in the "Liste of Basic Materials"

12. Epoxy resine e.g. Epidian 5 for gluing (use PAC hardener for gluing)
13. Epoxy resin e.g. EPIDIAN 6011

www.c-l.eu/epidian-5/
www.c-l.eu/epidian-6011/

IN the section Hardener there is 4 different products, (https://www.c-l.eu/hardeners/). I guess they all have a specific drying time.
It could be very helpful to know which one to use and which one not.

Same about EPIDIAN 6011 by the way.

Thanks in advance
