Fiber composite material and manufacturing method thereof

A fiber composite material, comprising:

• a fiber prepreg layer comprising a first resin and fibers impregnated in the first resin;
• and
• a plurality of strip-shaped composite resin layers disposed on the fiber prepreg layer, the plurality of the strip-shaped composite resin layers and the fiber prepreg layer together form a hollow tubular body having a lamination of multi-layer fiber prepreg layers to make the plurality of the strip-shaped composite resin layers interposed between the multi-layer fiber prepreg layers,
• wherein the plurality of the strip-shaped composite resin layers comprise multi-layered carbon nanotubes and a second resin, and a length direction of the plurality of the strip-shaped composite resin layers is at an angle of from 0 degree to less than 90 degrees with respect to an extending direction of the fiber prepreg layer.
