RANCANG BANGUN TURBIN ANGIN DENGAN BLADE SAVONIUS BERBAHAN KOMPOSIT HYBRID

This applied research discusses the design of wind turbines and the value of the mechanical strength of the hybrid composite produced from the combination of glass fiber and carbon with the vacuum infusion method. The purpose of this study is to look at the process and manufacture of the blade and the results of the mechanical strength characteristics (bending stress) on the blade. The design of the savonius wind turbine was made using Inventor software, while the turbine blade material was designed with variations in the fiber arrangement of 5AC (Random), 4AC 1C (4 Random-1 Carbon), 3AC 2C (3 Random-2 Carbon), 5 AN (Woven), 4AN 1C (4 Webbing-1 Carbon), 3AN 2C (3 Webbing-2 Carbon). The arrangement of channels uses the installation of 1 inlet and 2 outlets. Mariks uses Yucalac 157 BQTN-Ex polyester resin. Bending specimens are made according to ASTM D790-02 standards. The best bending test results were obtained in the 3AC2C variation with the highest stress values and bending modulus, namely 288.2 Mpa, 15.79 Gpa. The lowest stress results were obtained in the 3AN2C variation, which was 128.8 Mpa, while the highest modulus for the woven variation was 14.69 GPa.
