Glass fiber reinforced engineering thermoplastic compounds

The question is frequently put forward "Why reinforced thermoplastics? What does this offer that is an improvement over the unreinforced material or other competitive materials?" This is a fair question and the answer we find breaks into two main advantages.

A. Dimensional stability.
B. Performance / Weight Ratio benefit.

The dimensional stability of thermoplastics is notoriously poor. Not only are the materials subject to creep under sustained load, but also to extremely high expansion and contraction when cycled over a wide range of temperatures. Most thermoplastics, for example, have coefficient of thermal expansion of about ten times that of metals; therefore it is impossible to match large thermoplastics parts with metal parts if they are going to be subjected to a wide range of temperature extremes because the difference in coefficient of expansion will cause warping, bulking and cracking. The addition of glass fiber reinforcement provides a dramatic improvement in these two properties. Glass reinforced thermoplastics can be designed to withstand comparatively high loads for extended periods of time, without significant deformation. Additionally, the coefficient of thermal expansion of glass fiber reinforced thermoplastics is in the range of most diecasting metals.

Performance / Weight ratio refers generally to a whole host of properties aswell as cost that can be favourably achieved in glass reinforced thermoplastics with significant improvements over competitive materials such as metals and thermosets.

The property improvements are directly proportional to the glass content i.e. higher the loading better the properties. Glass fiber is likely to remain the dominant reinforcement used in composite materials, because it offers, for those who work with it, a broad mixture of physical properties along with excellent cost / performance benefits fora large number of end use applications.

Internally lubricated reinforced and unreinforced thermoplastics

The ease and economics of manufacturing gears, cams, bearings, slides, ratchets, etc., with injection moldable thermoplastic resins has led to the widespread displacement of metals for these applications. In addition to the inherent processing advantages, parts made from these materials have the ability to dampen shock and vibration, have reduced weight, run with less power, provide corrosion protection, run quietly and operate with low or no-maintenance.

These characteristics can be further enhanced and the application areas expanded by the addition of fillers, reinforcements and internal lubricants.

These additives, when extrusion compounded with the appropriate base resin, yields an almost limitless choice of compounds providing increased load carrying capacity, reduced coefficient of friction, improved wear life, higher mechanical strength, improved thermal properties, greater fatigue endurance, creep resistance, dimensional stability and reproducibility.

Lubricants used in these compounds are PTFE, silicone, graphite powder and MoS2.
