Abstract

The use of composite materials in a structure needs to be followed by a repair method in case damage occurs in the structure. The standard methods for repairing glass fiber reinforced composite in aircraft structures is mentioned in the AC 43.13-1B document. One of them is the scarf method, which is a composite repair method by making a scarf side connection between the base material and the patch. In this study, the repair process is carried out using two techniques, hand lay-up and vacuum bagging. The comparison of strength between the repairs by hand lay-up and vacuum bagging is sought by conducting a tensile test on each specimen according to the ASTM D3039 standard. The test results showed that the average tensile strength of the vacuum bagging specimen is 20% to the average tensile strength value of the hand lay-up specimen. This trend is also shown in the tensile strain and elastic modulus of the vacuum bagging specimen, which respectively have values of only 51.5% and 38% of the hand lay-up specimen.
