Improved Mechanical Properties of Aluminium Powder-Carbon Nanotubes and Epoxy Nanocomposites to Fabricate Blades for Wind Turbines and Different Components of Machines and Equipment
Blades for wind turbines are critical parts in the manufacture, design and operation of wind turbine power plants, they have to support extreme weather conditions sometimes at the same day like snow, rain, 50 degrees below 0 and +45 degrees temperatures without suffer any deformation, bending, crystallization, fracture, wear, support hurricanes and strength winds, have to be light weight or low density, not to decrease the structural behavior during the rotation and transmission of mechanicalpower. The main manufactures of wind turbines have specific research centers to improve the materials, most of the materials are special composites and affect the design and operation of wind turbines. In this study we have fabricated different combinations of aluminium powder, epoxy and carbon nano tubes to have a novel material with better structural properties, especially for small and medium size wind turbines in the Rank of 0.100 to 100 Kilowatts, for functionalization we modified the surface of aluminium powder and nanotubes with 3 aminopropyltriethoxysilane to have a bonding and adhesion with the epoxy and aluminium-nanotubes in the particulate Nano composite tensile, flexion, hardness test were performed in Universal testing machine and Vickers hardener tester, stress-strain curves of different combinations of particles and materials in the Nano composites and also compared with the standard materials utilized to fabricate the blades like, Nylon 6, carbon fiber, fiber glass are showed after the results of the different tests.
