Hello,
I build carbon fiber tubes with and without core. I can build the tube with a aramid honeycomb or with a hard foam core.
The hard foam core is the stiffest, the honeycomb ist the lightest.
For example will cost a 300/1200mm tube with 9mm wall and hard foam core and vanish/polished carbon fiber surface about 350 Euro. Shipping cost if the tube is 1200mm or shorter for about 60 Euro. Weight of the tube is about 4 Kg. With a aramid honeycomb and a 8mm wall the tube will weight 2,5 kg and cost about 500 euro.
Of course i can build all other diameters and length, but i didnīt found a shipping method for tubes longer than 1200mm, or no cheap shipping.
