The direction of the fibers' major axis, relative to the flow direction in fiber-filled materials as shown in the diagram below where:
1. Randomly-oriented fibers are found near the injection location.
2. Flow-aligned fibers are found in the converging flow area.
3. Transversely-aligned fibers are found in the diverging flow area.
4. Fibers parallel to the flow direction are found in the restricted flow area.
