That is probably the best
you can do without going to high modulus carbon.
From what I've seen on the net high modulus carbon really
only tows made up of smaller diameter carbon fibres.
The diameter of a 12 K HM carbon tow is about half that of
the normal carbon tow. Physically this means that there
can be about 5 X the number of carbon fibres / 1 mm2 of
HM laid up carbon The reason for this is that the smaller
fibres will be packed closer in the spar giving higher density
and therefore higher strength for a spar made of this material.
Quoted figures :- Normal carbon diameter of tow = 0.95 mm
High Modulus tow = 0.41 mm
