In composite fiber construction, what direction is warp on the fabric roll?

In composite fiber construction, warp refers to the fibers that run in the longitudinal direction of the fabric roll. This direction is considered to be at 0 degrees relative to the fabric's reference point. The warp fibers provide the primary strength and structural integrity to the composite material since they are aligned in the direction of the load that will be applied.

Understanding the orientation of warp is crucial for fabricating parts that require specific strength characteristics and structural properties. In contrast, the weft fibers run perpendicular to the warp, typically at 90 degrees. Therefore, when working with composite materials, recognizing the 0-degree orientation of warp is essential for proper layup and achieving the desired performance of the finished component.
