Abstract
Abstract
The article presents the results of research on the modification of Epidian 5 epoxy resin by introducing natural modifiers. It's easy accessibility and biodegradability has a positive effect on environmental protection, cost-effectiveness of the process, useful and strength properties of composites. Still looking for the best solutions in the production of epoxy composites combining these features, we have attempted to compare and select the most optimal natural modifier. The epoxy resin was modified with collagen, hemp fibres, cellulose from pepper extraction residues. The amount of amine hardener suggested by the manufacturer was added to the composition. Each composition was cured at room temperature for 24 hours and then cured at 80°C for 3 hours. The prepared composites were subjected to impact assessment additions for mechanical properties, impact strength, three-point bending strength, critical stress intensity factor and gel time.
