The bleached treatment of coir fibre composites were prepared using treated coir fiber and epoxy resin using handmade mould. XRD patterns confirm that degree of crystallinity decreases by the treatment of coir fibre with H2O2. SEM image shows roughness of surface structure of composites. It confirms from the SEM, that the adhesion is increased after treatment. FTIR study gives us information about the functional group present in the composite .The 3 point bending system or instron analysis tells about the flexural strength of the composite.
