Fish scales arouse interest as protective systems due to some of their features: small thickness, light weightiness, flexibility, and puncture resistance from attacks by predators, or from the collision with obstacles. The Arapaima gigas (known as pirarucu in Brazil) is a large freshwater fish from the Amazon Basin, and their scales are an excellent example of a natural protective system. In this work, composites were produced with epoxy matrix reinforced with 20, 30 and 40 vol% of arapaima scales, after they were submitted to a flattening process. The objective was to compare the Charpy impact energy of the composite specimens produced using different volumetric fractions of scales as reinforcement. The results show that the use of increasing volumetric fractions of arapaima scales as reinforcement increases the Charpy impact energy of the composites when compared to the pure epoxy resin.
