The Fiber-orientation flow analysis is used to predict the behavior of composite materials. While injection-molded fiber-reinforced thermoplastics constitute a major commercial application of short-fiber composite (a filler within a polymer matrix) materials, the modeling of the process is more complex than in other flow applications. In injection-molded composites, the fiber alignment (or orientation) distributions show a layered nature, and are affected by the filling speed, the processing conditions and material behavior, plus the fiber aspect ratio and concentration. Without proper consideration of the fiber behavior, there is a tendency to significantly overestimate the orientation levels. The Moldflow fiber orientation model allows significantly improved orientation prediction accuracy over a range of materials and fiber contents.

There are two basic types of plastic: thermosetting, which cannot be resoftened after being subjected to heat and pressure; and thermoplastic, which can be repeatedly softened and remolded by heat and pressure. When heat and pressure are applied to a thermoplastic binder, the chainlike polymers slide past each other, giving the material “plasticity.” However, when heat and pressure are initially applied to a thermosetting binder, the molecular chains become cross-linked, thus preventing any slippage if heat and pressure are reapplied.
