description:

1. Uniaxial (0° unidirectional): Only one layer of 0° unidirectional fibers, no other angles, used for pultusion and unidirectional load-bearing components of main beams.

2. Biaxial (0°/90° -- 0°/45° two-axis): Two of longitudinal 0°   transverse 90° laid perpendicularly; two layers of longitudinal 0°   transverse 45° laid perpendicularly.

3. Triaxial (°/ 45°/-45° three-axis): Longitudinal   bidirectional diagonal layers, mainstream for wind turbine blade main beams.

4. Quadaxial (0°/9°/ 45°/-45° four-axis): Four-way full coverage, multi-directional load-bearing structural components for aerospace and automotive industries.

Carbon fibers each layer are completely parallel, with no interlacing between layers.
