Popis:	The modern industrial materials require more sustainable and environmentally friendly alternatives. This trend has increased the attention on reinforced polymer composites with lignocellulosic fibers, such as the malva Fibers (Urena Lobata, L). These fibers composites present characteristics like a high impact absorption by the composite structure. This work aims to analyze the resistance to impacts of composites produced with polyester matrix and amounts ranging from 0% to 30% in volume of continuous and aligned malva fibers. The objective is to analyze how the Izod impact resistance improves with the incorporation of malva fibers, up to 30% in volume. The results showed a remarkable increase in the notch toughness with the amount of incorporated malva fibers. This can be attributed to a preferential debonding of the fiber/matrix interface, which contributes to an elevated absorbed energy.
