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.

Polycarbonate (PC)

Properties: Polycarbonates are strong, stiff, hard, tough, transparent engineering thermoplastics that can maintain rigidity up to 140oC and toughness down to -20°C or special grades even lower.

Applications: In recent years Polycarbonate blends have become increasingly commercially important. PC is widely used in blends due to its excellent compatibility with a range of polymers.

Typical Applications include: Electronic and business equipment (computer parts, connectors, etc.), appliances (food processors, refrigerator drawers, etc.), transportation (head lights, tail lights, instrument panels, etc.).

Polyethylene (High Density - HDPE)

Properties: Flexible, translucent / waxy, weatherproof, good low temperature toughness (to -60'C), easy to process by most methods, low cost, good chemical resistance.

Applications: Chemical drums, jerricans, carboys, toys, picnic ware, household and kitchenware, cable insulation, carrier bags, food wrapping material.

Poly-phenylene Oxide (PPO)

Properties: Rigid, opaque, good dimensional stability at high temperature and humidity conditions, difficult to process (blended to ease injection moulding), tough.

Applications: Coffee pot and washing m/c parts (where high temperature and moisture are critical), replacement for die castings, drink vending machines, microwave components.

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.
