Effect of fiber surface treatments on the fiber-matrix interaction in banana fiber reinforced polyester composites

Cellulosic Ž bers have been used as cost-cutting Ž llers in plastic industry. Among the various factors, the Ž nal performance of the composite materials depends to a large extent on the adhesion between the polymer matrix and the reinforcement and therefore on the quality of the interface. To achieve optimum performance of the end product, sufŽ cient interaction between the matrix resin and th...
