Abstract

Recycled  plastic  as  a  matrix  in  Wood-Plastic  Composite  (WPC)  has  been  one  of  the  major  interesting research subjects  due  to  its  availability  and  for  the  sake  of  environmental  concern.  In  this  study,  the  effect  of  different ratios  (100%,  90%,  80%,  70%,  60%  and  50%)  of  plastic  content  from  polypropylene  (PP),  high  density  polyethylene (HDPE) and low density polyethylene (LDPE) mixed with wood fibres (WF) from Acacia were used to produce WPCs and evaluated  for  their  mechanical  properties.  The  composite test  pieceswere  produced  by  hot-press  method  and  mould which  followed  ASTM  D638 -02  and ASTM  D790-02 for  tensile  properties  and flexural  properties  respectively.  It  was found that the performance of tensile strength was linearly increased with increasing amount of plastic content. WPCs of PP-WF, HDPE-WF and LDPE-WFhaving 100% plastic content showed highest tensile strength which were 25.02 N/mm², 16.41  N/mm²  and  12.45  N/mm²  respectively  for  different recycled plastic.  Modulus  of  Elasticity  (MOE)  and  Modulus  of Rupture (MOR) results showed that WPC with 100% PP had the highest with 1020.07 N/mm² for MOE followed by 417.30 N/mm²  and  371.81  N/mm²  respectively  for  100%  HDPE  and  100%  LDPE.  MOR  showed  highest  for  100%  PP  also  with 25.10 N/mm² as compared to HDPE only achieved 12.54 N/mm² and LDPE with 10.66 N/mm².
