Tub fibra carbon

-----------------------------------

Salutare tuturor,

Navigand pe diverse site-uri, am dat peste cineva care a facut  un tub de fibra de carbon.
In topicul asta:
https://www.cloudynights.com/topic/853087-how-to-construct-a-true-newtonian-astrograph/page-2
la postul # 26, zice asta;
"It is not difficult or expensive to make your own Carbon fiber tube.
I made one for a 6-inch astrograph by winding carbon cloth and epoxy onto a PVC pipe, covered in paper and plastic (so you can get it off).
You have to squeegee as you go, layer by layer to get a good cloth-resin ratio.
But epoxy can be dangerous, so be careful.  Gloves and good ventilation is a must:"

Pune si un link, dar fara multe alte explicatii:

Intrebarea mea este: credeti ca se poate face? A facut cineva asa ceva?

Costurile par mult mai mici, de exemplu un tub pt 8" (F4/F5) e in jur de 600 euro. Panza de fibra de carbon pare sa fie cam in jur de 60 euro metrul patrat:
