Influência da adição de particulados de exocarpo de licuri nas propriedades mecânicas de compósitos poliméricos reforçados com manta de vidro

Abstract

Given the environmental sustainability scenario, there is a growing demand for the use of solid waste generated in various industrial processes. Therefore, the reuse of different types of waste, especially those of plant origin, has become relevant for the creation of polymer composites. In this sense, the objective of this work was to analyze the influence of particulate matter from the exocarp of the licuri (Syagrus coronata (Mart.) Beccari) on the mechanical and physical behavior of polymer composites reinforced with a glass blanket. For this, three polymer matrix composite plates (orthophthalic polyester resin) with dimensions of 45x65 cm were produced and processed manually (hand lay up), in weight percentages of 0%, 2.5% and 5% of the waste. The specimens were tested to determine their mechanical and physical properties through uniaxial traction, three-point bending, water absorption and apparent density tests in accordance with specific technical standards. The composites were characterized through optical and scanning microscopic analyses. Therefore, through analysis of the results, it was concluded that the laminated composites had a loss in mechanical and physical properties when the licuri exocarp particles were added, and these could only be used as filler and not as reinforcement.
