Description
Summary:Quasicrystals (QC) are usually complex metal alloys with atypical structures. Due to their physical, mechanical and surface properties, quasicrystals have been widely studied. Although methods to manufacture quasicrystalline materials are well known, much effort has been expended in obtaining suitable quasicrystalline materials for use in industry. As quasicrystalline materials are very brittle, they are usually used in powder form as a reinforcement for additives in composites as well as in coating technology. In this work, Al-Cu-Fe quasicrystalline powder was used as a reinforcement in epoxy resin and the influence of the quasicrystal particles incorporation on the adhesive properties of the epoxy was investigated. Single lap joints (SLJ) adhesion tests were performed in order to assess the shear mode bond strength. Results show that the effect of QC reinforcement is not linear with respect to the adherence of the composites.
