A comparison process between hand lay-up, vacuum infusion and vacuum bagging method toward e-glass EW 185/lycal composites

This study about reinforced e glass fibers with processed of lycal composites resin by using hand lay-up, vacuum infusion, and vacuum bagging method. Plain-weave type woven glass fabric, commercial code: EW185 cloth, has been used as the GFRP. Experiments carried out include tensile testing to obtain tensile stress, tensile strain, and elastic modulus performed using UTM (Universal Testing Machine) tools. In addition, density, composite thickness, mass fraction and fraction of composite material volume and SEM (Scanning Electron Microscope) photographs can be determined to see the bond density between fibers and resins. Specimen preparation refers to ASTM D3039 which is the standard tensile test for composites with a polymeric matrix. Compared with hand lay-up, vacuum infusion, and vacuum bagging method, Vacuum infusion has the best ultimate tensile strength that is 346.15 MPa and average modulus elasticity is 10673.4 MPa. Failure Mode is also DAT.
