Carbon fiber tube with increased rigidity and decreased weight

A carbon fiber tube comprising:

• a first carbon fiber sheet having a plurality of first fibers parallel to a first axis and a plurality of second fibers parallel to a second axis, said first axis of said first carbon fiber sheet forms a lengthwise axis of a carbon fiber tube, said plurality of second fibers are cross weaved with said plurality of said first fibers of at substantially 90 degrees;
• a second carbon fiber sheet having a plurality of third fibers parallel to a third axis and a plurality of fourth fibers parallel to a fourth axis, said plurality of fourth fibers are cross weaved with said plurality of said first fibers of at substantially 90 degrees, said third axis of said second carbon fiber sheet is oriented about 45 degrees relative to said lengthwise axis;
• and
• a third carbon fiber sheet having a plurality of fifth fibers parallel to a fifth axis and a plurality of sixth fibers parallel to a sixth axis, said fifth axis of said third carbon fiber sheet is aligned with said lengthwise axis of said carbon fiber tube, said plurality of sixth fibers are cross weaved with said plurality of said fifth fibers at substantially 90 degrees.
