Twin-Screw Extrusion of PC/GF Blends: Validating a Robust Configuration for Fibre-Reinforced Thermoplastics
Glass fibre-reinforced thermoplastics are reshaping performance standards: they deliver higher stiffness, strength, and thermal stability without sacrificing processability. The twin-screw extruder is key to this evolution, enabling consistent dispersion and stable compounding of Fibre- Reinforced thermoplastics.
Glass fibre reinforced thermoplastics (GFRTs) are highperformance composite materials formed by embedding fine glass fibres into a thermoplastic polymer matrix. This reinforcement significantly enhances the mechanical and thermal properties of the base polymer, making the resulting composite suitable for demanding structural and functional applications.
The primary function of the glass fibres in these composites is to provide increased tensile strength, stiffness, and dimensional stability, particularly under mechanical stress or elevated temperatures. In addition, the glass fibres help to reduce shrinkage and warpage during cooling, improve creep resistance, and maintain integrity over prolonged use. These advantages make GFRTs highly suitable for applications in the automotive, electrical and electronics (E&E), consumer goods, and industrial equipment sectors.
