Loofah fiber as reinforcement material for composite. 6 6 - - - - - - - - . - . - 0 . - . - 0 .

ABSTRACT In this preliminary study, the potential of loofah fiber as reinforcement material for polymer-bonded composites was investigated. Tensile and flexural properties of loofah fiber reinforced plastic were characterized and evaluated. The mechanical properties of the composite have been determined as a function of different method of loofah fiber preparation. The fiber-matrix interaction and fiber/matrix volume were also determined using a stereomicroscope. Results of mechanical properties, at least in this study showed that loofah fiber reinforced with unsaturated polyester are typical anisotropic material since the loofah is generally controlled by the network of fibers in multi-directions. The concentration of fibers in the loofah itself has a significant effect on the mechanical properties as shown from the results of transverse and longitudinal direction. The tensile and flexural modulus varied depending on the sample preparation of the composite and the direction of loading.
