A Comparison Between Polyester and Vinylester Matrice Toward E-Glass WR 185 Polymer Composites for Unmanned Aerial Vehicle (LSU 05 NG)

This study about reinforced e-glass WR 185 fibers with processed of vinylester and polyester composites resin by using vacuum bagging method. Experiments carried out include tensile testing to obtain tensile stress, tensile strain, and elastic modulus performed using UTM (Universal Testing Machine) tools. Specimen preparation refers to ASTM D3039 which is the standard tensile test for composites with a polymeric matrix. the results of testing of composite specimens of e-Glass WR 185 matrix of Polyester and Vinylester, namely the Value of Composite Tensile Strength of WR 185 matrix Polyester Fiber is greater, namely 424.65 MPa, with modulus of elasticity 8.64 GPa. Whereas for vinylester 385.61 MPa, modulus of elasticity of 7.74 GPa. This means that the tensile strength value of the polyester is better than vinylestermatrices.
