The aim of this paper was the effects of different fiber size on tensile and flexural properties. Preparation of thermoset unsaturated polyester reinforced with particle Bertam (Eugeissona tristis) was done by hand layout method. Bertam/polyester composites containing Bertam fiber of different sizes, i.e., 15, 120 and 284 μm were prepared. For each composite, eight specimens were tested to evaluate the mechanical properties. It was found that composite reinforced with Bertam having the shortest fiber length, i.e, 15 μm showed the highest tensile and flexural modulus, which were 204.14 MPa and 1826.78 MPa, respectively.

Issues pertaining to deforestation, environmental pollution and natural wastes are increasing day by day. These issues can be resolved by introducing a new composite material, in which natural waste is used as fibre and as a replacement of wood plastic composite. The different lengths (3, 6 and 9 cm) of corn husk fibre filled polyester composites were produced using the vacuum infusion method. Several mechanical properties of these polyester composites, such as tensile and flexural properties, were evaluated. The results revealed that both the tensile and flexural properties of polyester composites increased with increment of corn husk fibre length from 3 to 6 cm. However, the results decreased for 9 cm of fibre length filled composites. Similar trends were recorded after alkali treatment of the corn husk fibre filled polyester composites. The alkali treatment with sodium hydroxide had improved the tensile strength (33%), Young’s modulus (23%), elongation (14%), flexural strength (42%) and flexural modulus (8.5%) of the polyester/corn husk fibre composites with 6 cm of fibre length by enhancing the mechanical interlocking bonding between treated corn husk fibres and polyester.
