I did forgot that we don't have all the same settings...

That part seems ok, but I've got a doubt for your density.
Usually carbon/resin composites are heavier (density of water is 1000 kg/m3, I think you should find around 1500 kg/m3 = 1.5E-6 kg/mm3)
I'll do some math to see want I get !
EDIT : I did some "maths"
ID = 0.4" = 0.01016 m
OD = 0.53" = 0.013462 m
W = 0.05 lbs/ft = 0,0744082 kg/m
Then, the surface of the tube section is S = pi*((OD/2)^2 - (ID/2)^2) = 6.126093.1E-5 m2
And D = W/S = 1214.6 kg/m3 = 1.2146E-6 kg/mm3
