Abstract In this study, the influence of sodium hydroxide (NaOH) treatment and
microwave treatment of coir fibers on the mechanical and physical properties of
pressed coir fiber/epoxy composite were evaluated. The composite was fabricated
with a hand lay-up method with compression molding. Before composite fabrication, pressed coir fiber was treated with NaOH and microwave treatments.
Mechanical testing (tensile, flexural, and impact testing) of the composite was
conducted. Then, water absorption and thickness swelling testing are also performed. The fractured composite surface morphology after the tensile test was analyzed by scanning electronic microscopy (SEM). The results revealed that tensile,
flexural, and impact… More >
