      High-Density Polyethylene Composites.

AB  - This study investigated the influence of viscose fibre (VF) geometry on the 
      microstructures and resulting properties of high-density polyethylene (HDPE) 
      composites. Seven types of viscose fibres varying in cross-section shape, linear 
      density, and length were pelletised, compounded into HDPE with a twin-screw 
      extruder, and injection moulded. The microstructures of the composites were 
      characterised by investigating their cross-sections and by extracting the fibres 
      and measuring their lengths using optical microscopy (OM). The mechanical and 
      thermal properties of the composites were characterised using differential 
      scanning calorimetry (DSC), tensile tests, Charpy impact tests, and dynamic 
      mechanical analysis (DMA). The composites prepared using cylindrical fibres with 
      a linear density of 1.7 dtex exhibited the best fibre dispersion, highest 
      orientation, and lowest fibre-fibre contact area. The decrease in the linear 
      density of the cylindrical fibres resulted in increasingly worse dispersion and 
      orientation, while composites containing non-cylindrical fibres exhibited a 
      comparably larger fibre-fibre contact area. The initial fibre length of about 3 
      to 10 mm decreased to the mean values of 0.29 mm to 0.41 mm during processing, 
      depending on the initial geometry. In general, cylindrical fibres exhibited a 
      superior reinforcing effect in comparison to non-cylindrical fibres. The 
      composites containing cylindrical fibres with a linear density of 1.7 dtex and a 
      length of 5 mm exhibited the best reinforcing effect with an increase in tensile 
      modulus and strength of 323% and 141%, respectively.
