Abstract
Epoxies as structural adhesives are used in a wide variety of structures, used in a wide variety of environments, for joining components made of different materials. However, there are limitations to the use of epoxies as structural adhesives in certain areas due to their delamination, low impact strength, inherent brittleness and low crack resistance. The mentioned limitations can be overcome by incorporating various modifying agents and their modification prior to their industrial application. Nowadays, modified epoxy resins are widely used for the manufacture of natural fiber-reinforced composites and various industrial products due to their excellent mechanical, thermal and electrical properties.
The chapter includes an introduction to the subject of modification of adhesives prepared on the basis of epoxy resins and curing agents characteristics and their properties, description of curing types, and properties and types of fillers. A separate section is dedicated to biofillers. It provides an overview of biofillers, their characteristics, and description of the properties of various biofilled epoxy adhesives.
