The trend of this research is focused on the development of coir fibre reinforced epoxy composites. Many researchers have been investigated the effects of coir fibre fibrillation on the tensile strength. The sorting treatment to this coir based on the uniformity of diameters and the fiber was cut between 10-20 mm. The preliminary treatment was done by cooking the coir in 5% NaOH solution in 80∘C for approximately 10-15 minutes. This process then can be addressed to the fibrillation process. This process was carried out by using a high-speed blender at 5 and 10 minutes, respectively. After that, the composite was formed by hand lay-up, with the composition coir volume fraction and matrix of 20:80. The results show that the treated Coir can increase the composite tensile strength upto 14%. The highest tensile Strength was obtained for EAC 10-10 composite on vial volume of 30% fiber and 70% epoxy i.e.53.70 MPa.     Keywords: coir, composites epoxy, fibrillation treatment, tensile strength
