Glass Fibre Reinforced PP

Glass fibres are used to confer enhanced strength and rigidity. These fibres are usually coated with silanes, lubricants, film formers and, sometimes, antioxidants and antistatic agents. These coatings provide better fibre-matrix adhesion, consequently enhancing the mechanical properties of the product. These coatings are also intended to reduce

Noble Polymers supplies a 6% nanoclay-PP composite for the structural seat back of the Honda Accura TL 2004 car. It replaces a 30% glass PP compound in the seat back. Noble Polymers is also targeting the replacement of 20% glass fibre reinforced PP in office furniture parts. Southern Clay Products supplies Cloisite nanocomposite external parts to General Motors for its Impala vehicle, in competition with talc-filled PP. 

Researchers at Union Carbide [51] reported that the incorporation of 2% of an organosilicone compound into recycled, 38% glass fibre reinforced PP increased the mechanical properties of the recycled sheet with an increase in tensile and flexnral strength of 35-40%. Izod impact strength was increased by 30%. 

The specific wear rate for liquid crystal polymers, 30% glass fibre reinforced PA 4,6 and 30% glass fibre reinforced PPS increased with the increase in sliding resistance. 

Blinkhorn and co-workers [35] developed a new glass fibre reinforced PP substrate for use in car interiors as a semi-structural and acoustic material. It is available in a number of weights per unit area and with various proportions of glass. The composite...
