STRUCTURE-PROPERTY RELATIONSHIPS IN PET NANOCOMPOSITE FIBRES

摘要

Poly(ethylene terephthalate) (PET) resin has been compounded with various organoclay layered-silicates. Processing methods included double-pass compounding using single screw extrusion and injection moulding various test specimens. PET nanocomposite compounds were also melt-spun into fibres using a capillary rheometer at draw speeds of 80 and 800m/min. Morphology and mechanical properties of these nanocomposite fibres have been analysed. The results show that organoclays can be incorporated into PET fibre matrix with good interclation and exfoliation, showing significant improvements in mechanical performance.
