The increasing energy and decreasing efficiency in the present and future generations of Industries have become the major issues. This can be achieved by minimizing the weight and increasing the efficiency of the fan blades. In this invention, the design and analysis of fan blade which is made up of natural fibers (hemp fiber and basalt rock fiber) is carried out, design, fabrication and testing of composite fan blade (using glass fiber material) and also composite blade is tested and compared with existing blade. In this project the composite blade has been designed and fabricated. The existing fan blade weighs about 295grams where as the weight of composite fan blade is 215grams, which is 28% lesser than existing blade. It is observed that the power consumed by the existing blade (0.052units) is more as compared with composite blade(0.037units). so there is reduction of 30% of power consumption by the existing ceiling fan. Cost of composite ceiling fan blade is Rs. 279/- which is 44% less than existing aluminum blade. The strength of the composite blade almost equalwith compared aluminum blade. From the study, it is concluded that fiber reinforced plastic material is a suitable material for manufacturing the composite ceiling fan blade. The major advantageof composite material ceiling fan blade as compared with conventional aluminium blade are High strength to weight ratio, Excellent corrosion resistance., Good aesthetic appearance, No need for painting, and Weight reduction.
