    abstract = {This study is aimed at to investigate the effect of surface 
  modification through NaOH (Sodium hydroxide) treatment and fiber length on the 
  tensile strength of coir fiber of reinforced epoxy composites. The coir fibers 
  was treated with 2, 4, 6, 8 and 10% concentration of NaOH separately for 10 
  days.The tensile strength of untreated and alkali treated fiber was measured. 
  For each group of the coir fiber experiments were conducted on different fiber 
  lengths, namely; 10, 20 and 30 mm. The experimental results showed that increasing 
  NaOH concentration leads to a decrease in fiber diameter in a linear fashion. 
  This reduction in diameter naturally ends up with reduced tensile strengths. 
  The treated coir fiber was used as a reinforcement and epoxy as a matrix to 
  fabricate the composites. The tensile strength of different samples of composites 
  was measured. Increased NaOH concentration in fibers treatment was found to 
  increase the tensile strength up to 4% and further increase in NaOH concentration 
  reduces the tensile strength and also increased fiber length was found to increase 
  in tensile strength. Maximum tensile strength of the composite was found to 
  be uniformly accruing for 4% NaOH treated samples. Based on the nonlinear regression 
  analysis the tensile strength equation was proposed for coir fiber reinforced 
  epoxy composites.}
