To understand the contribution of bamboo bers in a composite system, the characteristics of the ber should be comprehensively evaluated. One of the major issues regarding the use of natural bers in the polymer composite industry is the incompatibility between the hydrophilic bers and the hydrophobic polymer resin, which weakens interfacial adhesion, leading to ineffective load transfer from the matrix resin to the reinforcing bers. One of the most recent and effective techniques for improving interfacial adhesion between natural bers and polymer matrices is alkali treatment, which involves the immersion of bers in sodium hydroxide (NaOH) solution.
