Development and Characterization of Spray Pyrolysis Nickel Coated Natural Bamboo Fiber Reinforced Polymer Composite

The escalating demand for electricity and the depletion of nonrenewable resources necessitate a transition to renewable energy sources, notably wind power. Wind turbines, pivotal in this transition, rely on sturdy turbine blades traditionally composed of polyester resin and glass fiber for strength and stiffness. However, the nonrenewable and non-biodegradable nature of these materials prompts a search for more sustainable alternatives. Natural fibers, such as bamboo, emerge as promising substitutes due to their abundance and environmental friendliness. While natural fibers may not match the strength of glass fiber, innovative solutions like metal coating, employing nickel through spray pyrolysis, bolster the mechanical properties of the composite material. This approach facilitates the replacement of up to thirty percent of the glass fiber, promoting sustainability without compromising performance. The application of nickel coating not only enhances strength but also provides exceptional corrosion resistance, crucial for withstanding harsh environmental conditions over the windmill's anticipated twenty-five-year lifespan. Moreover, the thin layer of metal coating mitigates the risk of debonding associated with gel coatings, ensuring structural integrity and longevity. Mechanical tests, including tensile, flexural, hardness, and wear resistance evaluations, validate the efficacy of the newly coated fiber-reinforced polymer composites. The results demonstrate improved mechanical properties, affirming the viability of this eco-friendly solution for wind turbine blades.
