This mechanism of reduction in fatigue life cycle due to water content is examined by scanning electron microscopy and dynamic mechanical analysis. The result showed that longitudinally oriented fibers exhibit better mechanical properties than the randomly oriented fibers. Test specimens were prepared with untreated fiber and treated with alkaline solution of sodium hydroxide. The Fourier transform infrared spectroscopy was used to characterize the modification effect of sisal fiber.

The water absorption was high for untreated sisal/PLA composite compared to all other composites in the present study. CM method was used for the fab, composite. The natural fibers extracted by retting and manual processes were subjected to alkali treatment. An attempt has been made in this research by taking CG fibre in the form of twisted yarn as reinforcement. The grey relational results observed 7th and 14th trials were having first and second position in mechanical properties: 10% sisal, 15% banana, 8% NaOH, 10 MPa pressure, and 100°C temperature composites; 20% sisal, 10% banana, 5% NaOH, 10 MPa pressure, and 120°C temperature were the combinations. Hard fiber sisal has high tensile strength, resistance to seawater immersion, friction resistance, flexibility and other characteristics, can be used for fishing, sailing, mining, transportation rope, canvas, waterproof cloth and other raw materials. The results show that the chemical treatments enhance the removal of lignin and hemicelluloses which are detrimental to the bonding strength of composite produced from natural fibres except that of sample treated with alkaline peroxide. Untreated sisal/PLA composite has high thermal degradation temperature compared to composite with treated fibers but lower than that of pure PLA. The developments of new materials are increasing, especially in the automobile, aerospace, aviation and construction industries. The major contribution of this change should be that the morphology of fibers could be well preserved in elongational flow field, which based on the vane extruder showed a good application in fiber-reinforced composites. The PP/RH composites prepared by extrusion with contents from 2 to 20 wt% of non-pyrolyzed (NRH) and pyrolyzed (PRH) rice husk were submitted to the injection molding for preparation of tensile and impact specimens and characterized by mechanical testing, thermal analysis, melt flow rate, infrared spectroscopy and scanning electron microscopy. alkaline treatment of sisal fibres with various concentrations and result obtained. Sisal leaves were cut and buried underground close to the stream and were wetted with water regularly in order to ensure proper fermentation for about 15 days. It is helpful for the development and application of natural fibers reinforced composites. The morphology of bambooâepoxy nanocomposites was investigated by using scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. Ultrasound sonication was used for the dispersion of nanoclay in the bambooâepoxy composites. Higher scatter in the data in the samples is addressed in the present studies. îese methods can be em, îe mechanical properties of diîerent si, the îbre and the polymer matrix used. Maleic anhydride-grafted polypropylene was used as compatilizer to increase the fiber/matrix interactions. Calotropis Gigantea (CG) is a shrub plant that grows rampantly in South Asia. Sisal fibers were pretreated by alkali and maleic anhydride, and then mixed with polypropylene to fabricate sisal fiber-reinforced composites by a self-made vane extruder based on elongational flow field. 33 Girisha et.al [8] investigated the tensile properties of composites made by reinforcing sisal, coconut spathe and ridge gourd as the new natural fibers into epoxy resin matrix. Various fibre treatments, which are carried out in order to improve adhesion, leading to improved mechanical properties, are also discussed in this review paper. The results show that samples with 2.5% sisal powder content in the unsaturated orthophthalic polyester resin (UP) matrix increase the mechanical properties of tension (0.54 MPa), deformation (2.8%), rigidity (11.64 MN/m), MOE (0.019 MPa), breakdown energy (5.94 J), and tenacity (0.75 MJ/m3), as well as exhibited low water uptake (1.7%) when compared to samples with 5% content of sisal powder. The chemically treated natural fibre shows, A composite material can be defined as a macroscopic combination of two or more distinct materials, having a recognizable interface between them. îe îexural strength, îexural modul, the best result.
