This paper aims at introducing and investigating the mechanical properties of new variety of natural fibers (Christmas palm fiber) used as reinforcement in polymer matrix composites. It was inferred that the poor inter laminar bonding between the Christmas palm fibers and polyester matrix restricted the mechanical properties of the composites. Hence surface modifications of Christmas palm fibers by means of alkali treatment were done in a view to enhance the bonding nature of the Christmas palm fiber with polyester matrix. The composite fabrication is carried out using compression moulding machine and the mechanical properties were tested as per ASTM standards. The effect of soaking time and solution concentration of Sodium hydroxide on the mechanical properties of Christmas palm fiber reinforced polyester composites were studied and fiber treatment conditions for better mechanical properties are identified. Scanning electron microscopy (SEM) investigations showed that surface modification improved the fiber/ matrix adhesion which in turn enhanced the mechanical properties of the Christmas palm fiber reinforced polyester composite.

AbstractMechanical properties of fiber reinforcement that can be obtained by the introduction of basalt fibers in jute fiber-reinforced polyester composites have been analyzed experimentally. Basalt/jute fiber-reinforced hybrid polymer composites were fabricated with a varying fiber percentage by using compression molding techniques. The fabricated composite plates were subjected to mechanical testing to estimate tensile strength, flexural strength and impact strength of the composites. The effect of fiber content on basalt/jute fiber in the composites has been studied. Addition of jute fiber into basalt fiber composite makes it a cost-effective one. Incorporation of basalt fiber into the composites was at approximately 10%, 20%, up to 90%, and the jute fiber percentage was reduced from 90%, 80%, to 10% correspondingly. Mechanical properties were investigated as per ASTM standards. Tensile and flexural strengths were tested by using a computer-assisted universal testing machine, and impact strength by using an Izod impact tester. It has been observed that the addition of jute fiber to the basalt fiber polyester composites enhanced the mechanical properties. Water absorption of hybrid composites was also analyzed and was found to be proportional to fiber percentage.

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.
