Summary:
Epoxy resins are the most common structural adhesives due to their good mechanical, thermal and chemical properties. However, the structure of these thermoset polymers, due the high crosslinking, also causes brittleness, with a low resistance to the initiation of cracks and their propagation. The inclusion of particles (nano or micro) is a common method to improve the mechanical properties such as toughness of structural adhesives [1]. In the present study, natural micro particles of cork were used to increase the toughness of a brittle epoxy adhesive. The main objective of this research was to investigate the effect of the amount of cork particles in the cure reaction of a brittle epoxy, knowing that the amount present influences the mechanical properties [2, 3]. This study was developed using specimens with 0.5, 1, 2 and 5% (volume) of cork and without cork, as reinforcement material of a brittle resin.
