What is a reference diagram that designates the angles of ply orientation in a composite component called?

The term used for a reference diagram that designates the angles of ply orientation in a composite component is known as the "warp clock." This diagram is crucial in composite manufacturing, as it provides the specific angles at which the fibers are oriented relative to a reference direction, which is typically aligned with the primary load path in the component.

Understanding ply orientation is vital because it directly influences the mechanical properties of the composite material, such as strength and stiffness. The warp clock allows engineers and technicians to visualize and communicate how the plies are laid out within the laminate, ensuring that the composite structure can withstand the required loads and stresses during its service life. Proper ply orientation can help in maximizing performance and reliability in aerospace applications.

In contrast, while terms like ply diagram, stacking guide, and material orientation chart may sound appropriate, they do not specifically refer to the angled orientation depiction of composite plies in the same way that a warp clock does. Each of these other terms may relate to composite materials but may describe different aspects of the composite layup process or documentation.
