Abstract :
Currently UAV (Unmanned Aerial Vehicle) aircraft are experiencing developments so that they can help human work including being used as a tool for aerial photography, reconnaissance, observation, helping agriculture in watering, applying fertilizers, and pepticides, and others. For that, a lightweight and strong material is needed for the manufacture of UAV aircraft, one of which is a composite. In this research, tensile and bending test of carbon fiber composite were carried out with variations in fiber direction 0º-45º-90º and 0º-30º-60º to determine the mechanical properties especially wit resin lycal. In the process of making the tensile test specimen the vaccum bagging method used. For the dimensions of each tensile test specimen using reference ASTM D3039 while bending testing using reference ASTM D7264. Before carrying out the manufacturing process, the volume fraction is calculated to determinethe needs of the material to be used. Tensile and bending tests are carried out using UTM (Universal Testing Machine). The result obtained after the tensile test were that the average tensile stress value in the direction of the fiber 0º-45º-90º was greater is 951,56 MPa compared to the fiber direction 0º-30º-60º which was 116,64 MPa. For the average value of the modulus elasticity in the 0º-45º-90º direction greater is 9331,63 MPa compared to the 0º-30º-60º fiber direction which is 3762,17 MPa. For the bending test the average value of bending stress with direction of the fiber 0º-45º-90º is greater, namely 724,20 MPa compared to the fiber direction of 0º?30º-60º which is 222,69 MPa.
