Popis: This paper provides a precise overview on surface treatment applied to natural fibers for advanced composites applications. The main objective of author was to build a composite system which has a high performance and is a green-composite and cost-effective. work was to optimize the length of bio-fibers for the production of economical & high strength to weight bio-fiber reinforced hybrid bio-composites for the transportation and automotive industry applications. This research work was mainly concerned with the fabrication of vinyl ester-unsaturated polyester matrix blend hybrid biocomposites. Bio-fiber composites were fabricated by reinforcing bagasse-henequen fibers into the matrix blend. Fiber length & chemical treatment of fibers influence the mechanical performance of the composites. In addition to this, the surface of the fibers were chemically modified by alkali treatment and in the present work the aim was to evaluate the effect of fiber surface modification by chemical on the fiber/matrix interaction for different fiber lengths. The investigation of tensile, impact & flexural properties of bagasse-henequen fibers reinforced hybrid biocomposites with and without alkali treatment was carried out. The above mentioned properties were found to be maximum for alkali (5 % NaoH) treated bagasse-henequen fibers reinforced hybrid biocomposites than the unprocessed as well as 10 % NaoH treated biocomposites. Variation of above said mechanical properties, also studied for the different fiber lengths such as 1 cm, 2 cm and 3 cm. The mechanical properties were found to exhibit maximum/optimum values at 2 cm fiber length and 5 % NaoH treated biocomposites.
