Natural areca fibers were treated with sodium hydroxide, potassium permanganate, benzoyl chloride and acrylic acid to improve interfacial adhesion between the areca fiber and epoxy resin and to fabricate areca fiber reinforced epoxy composites with improved mechanical properties. The untreated and chemically treated areca fiber reinforced epoxy composites were prepared with 40%, 50%, 60% and 70% fiber loadings. The investigation of flexural strength was done for all areca/epoxy composites. Untreated and chemically treated areca/epoxy composites with 60% fiber loading showed higher flexural strength values. The acrylic acid treated areca fiber reinforced epoxy composites with 60% fiber loading showed highest flexural strength values amongst all untreated and chemically treated areca/epoxy composites with same 60% fiber loading.
