Abstract

The world of aerospace in its development is experiencing rapid progress such as UAV (Unmanned Aerial Vehicle) aircraft. Construction materials for UAVs require materials that are light but still strong and rigid such as hybrid composites. In the process of making tensile test specimens, the vacuum infusion method is used. For the dimensions of each specimen the tensile test uses the ASTM D3039 reference. Before carrying out the manufacturing process, the volume fraction is calculated first. Tensile testing is carried out using the Universal Testing Machine (UTM). The results obtained after the tensile test are the ultimate tensile strength value for the kevlar and carbon fiber hybrid composites, which is 447,525 MPa compared to the carbon fiber and glass fiber hybrid composites, which are 434,113 MPa or the kevlar and glass fiber hybrid composites, which are 399,380 MPa. The average ultimate tensile strain value for hybrid composites of kevlar fiber and glass fiber is greater that is 0,0780 compared to hybrid composites of kevlar and carbon fiber which is 0,0576 or hybrid composites of carbon fiber and glass fiber is 0,0553. The average value of the modulus of elasticity for the hybrid composite of carbon fiber and glass fiber is 5,340 GPa compared to the hybrid composite of carbon fiber and kevlar fiber which is 4,828 GPa or the hybrid composite of kevlar fiber and glass fiber is 2,979 GPa.
