In this chapter, three different types of natural fibers namely jute, banana, and bamboo fibers were used as reinforcing material to fabricate the three different types of composite laminates. The composites were prepared by taking 50–60% weight fraction of the fiber. Two different types of chemical treatments of natural fibers were carried out to study the effect of chemical treatment of natural fibers on the mechanical properties (tensile and flexural) of the developed composites. The natural fibers were treated with (i) 5% of sodium hydroxide (NaOH) for 4 h and (ii) 5% NaOH for 4 h followed by 1% of potassium hydroxide (KOH) and 1% of hydrogen peroxide (H2O2) for 2 h. The mechanical properties such as (i) tensile strength, modulus, and percentage elongation and (ii) flexural strength, modulus, and percentage elongation of the developed composites were evaluated. The results indicate that natural fibers treated with 5% NaOH, 1% KOH, and 1% H2O2 resulted in better mechanical properties than the 5% NaOH treated natural fiber-based composites.
