      Composites.

AB  - Fly ash polymer composites are innovative high-performance materials that reduce 
      the environmental worries and disposal complications of heavy industry produced 
      fly ash. This study developed and characterized such composites of high-density 
      polyethylene (HDPE) matrices and found that the use of small (50-90 microm) particles 
      of fly ash could give rise to the tensile modulus (~95%) and tensile strength 
      (~7%) of their reinforced composites when compared to neat HDPE materials. While 
      these results themselves convey a strong message of how fly ash can be 
      effectively utilized, this was not the key aim of the current study. The study 
      was extended to examine the effect of fly ash particle size on the recyclability 
      of relevant HDPE composites. The extrusion-based multiple recycling of composites 
      gave slightly lower mechanical properties, primarily due to filler/matrix 
      delamination when large fly ash particles were used. Compared to freshly made fly 
      ash-filled HDPE composites, although using small (50-90 microm) fly ash particles 
      reduced the tensile modulus and tensile strength of recycled composites, the 
      values were still far above those from neat HDPE materials. This novel insight 
      directs the effective utilization of fly ash and provides long-term sustainable 
      and economical solutions for their practical applicability.
