AB  - Nowadays, there is an increasing concern toward substituting the scarce wood 
      fibers with alternative lignocellulosic fibers that originate from crop residue 
      to reinforce biocomposites. In this paper, the potential application of coffee 
      hull (CH) of the reinforced polyethylene (PE) matrix composites was studied for 
      the first time. Experiments of composite that enhanced with CH on mechanical 
      properties, hydroscopicity, thermogravimetric analysis, fiber treatment, and 
      microstructures were tested in this study. The PE matrix was reinforced with 
      varying volume fractions of CH and was studied. The results show that 
      incorporation of coffee hull markedly improved the mechanical properties of the 
      reinforced high-density polyethylene (HDPE) matrix composites. Micrographs show a 
      strong interfacial adhesion between the CH fiber particles. This property may be 
      the main reason for the stability between composites. At the same time this work 
      investigated the effect of different treatments on the mechanical properties and 
      water absorption behavior of composites. The fiber surface treatments were done 
      using active chemicals such as calcium hydroxide (Ca(OH)(2)), silane coupling 
      agent (SCA), maleic anhydride grafted polypropylene (MA-g-PP), stearic acid (SA), 
      ethylene bis stearamide (EBS) and the combination (MA-g-PP, SA, EBS). The results 
      show that (Ca(OH)(2))treatment is the best way to improve its properties. 
      Probably because attributed to removal of surface active functional groups (-OH) 
      from the CH fiber and induction of hydrophobicity that in turn improved the 
      compatibility with the polymer matrix. As a result, the use of coffee hull in 
      composites could have great significance for the industry.
