Composite Materials with the Hybrid Matrix Based on Rosin and the Reinforcement from Agricultural Waste - Chemical Structure and Mechanical Properties

The manufacture of composite materials with hybrid matrix and reinforcements from agricultural waste, which have properties/structure corresponding to the field where they will to be used, is a challenge both in terms of environmental protection and low production costs.Based on this premise, in this article, composite materials reinforced with crushed sunflower seed shells or chopped wheat straw were fabricated, and a hybrid resin matrix based on rosin was used.The chemical structure was studied, along with the influence of the reinforcement addition on the morphology of the materials and their behaviour under various mechanical solicitations: tension and compression.
