AbstractThis investigation is carried out to understand the effects of water absorption on the mechanical properties of hybrid phenol formaldehyde (PF) composite fabricated with Areca Fine Fibres (AFFs) and Calotropis Gigantea Fibre (CGF). Hybrid CGF/AFF/PF composites were manufactured using the hand layup technique at varying weight percentages of fibre reinforcement (25, 35 and 45%). Hybrid composite having 35 wt.% showed better mechanical properties (tensile strength ca. 59 MPa, flexural strength ca. 73 MPa and impact strength 1.43 kJ/m2) under wet and dry conditions as compared to the other hybrid composites. In general, the inclusion of the fibres enhanced the mechanical properties of neat PF. Increase in the fibre content increased the water absorption, however, after 120 h of immersion, all the composites attained an equilibrium state.

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.

The present paper discovers the effect of ceramic filler inclusion on physico-mechanical and water absorption behaviour of untreated and chemically treated (alkali and benzoyl chloride treated) bi-directional jute natural-fiber-reinforced epoxy composites. In practice, the major drawbacks of using natural fibers are their high degree of moisture absorption and poor dimensional stability. Currently, chemical treatments are able to induce fiber modifications that increase their resistance when utilized in composite products. Jute fibers were subjected to various chemical modifications to improve the interfacial bonding with the matrix. In this study, an analysis has been carried out to make pre-treated jute fiber (10, 20, 30 and 40 wt.%) and different filler content (5 and 10 wt.%) with epoxy-based composites. A comparative study of all the untreated jute/aluminium oxide based hybrid composites with chemically treated jute/aluminium oxide based hybrid composites was carried out. The investigational result reveals that chemically treated composites considerably improved the mechanical properties of the composite. The maximum water absorption resistance and strength properties were found with benzoyl chloride-treated fiber-reinforced composite. Lastly, the surface morphology of fractured surfaces after tensile and flexural testing is studied using scanning electron microscope.

This paper focus on Madar and Bauhinia Racemosa fibers has high potential as reinforcing agents in polymer composites. The composites plates were fabricated by hand layup method with varying the fiber weight percentage of 5%,10%,15% and 20% on mechanical and water absorption properties are analyzed. The mechanical properties of such as tensile, flexural and impact properties of madar and Bauhinia Racemosa fiber mat reinforced polyester composites were studied at first time in this work. The tensile, flexural and impact strength of Bauhinia Racemosa fiber mat reinforced polyester composites had proved higher strength performance than the madar fiber mat reinforced polyester composites.
