Adhesive bonding will be used for bonding components in aerospace and transportation industry in the future and will be replacing bolted joints. Researchers have conducted experiments to improve the adhesive bonding, one of them is adding filler materials to the adhesive. Determining properties such as lap shear strength, peel strength, and failure modes are mainly the objective of this research in order to know the effect of filler materials for the metal-to-metal adhesive bonding properties. The experimental part of this research is done to determine the lap shear strength and peel strength of metal-to-metal adhesive bonding with addition of filler material, which conducted in PT. Dirgantara Indonesia. The materials that will be used in the experiment are aluminium LP-3140-T3 for the adherends, adhesive film FM- 73M.OST.06 for the adhesive, and Cerex® fabric for filler material. Digital microscope analysis is done in this research to determine the failure modes that occurs on each specimen. The result of single-lap shear test showed that the average lap shear strength of specimens with filler material do not have significant difference with specimens without filler material. The result of floating roller test showed that the average peel strength of specimens with filler material is lower than specimens without filler material. Failure mode that occurs on specimens with filler material is mixed-mode failure.
