Study on Development of a Geotextile Coated with Latex Using as a Protection Element on Heated Surfaces

Today, much research has been conducted on new energy resources and sustainable materials with the goal of reducing the environmental impact. Materials waste that were previously destined for the landfill are now viewed in a new light. The goal of this paper was to create a geotextile out of banana tree leaves, specifically fibers extracted from the stem of the banana tree leaves, which are now recognized as one of the strongest cellulosic fibers. Latex was used as a natural geotextile matrix, and potential applications for the geotextile were investigated using previous material characterization based on literature. After weaving and covering the samples with látex, the main physicalchemical properties, as well as mechanical and thermal properties, were analyzed and verified. Tensile properties, flammability, thermogravimetric analysis, water and humidity absorption, moisture resistance, friction, density, weight, biodegradation under environmental conditions, and thermal conductivity were among the tests used to obtain such results. Based on the results obtained, it was possible to conclude that geotextile can be used as a surface coating because, in addition to its high tensile strength even when heated, The thermal conductivity of the goetextile is low (0,214W/mK). This means that the material has good thermal properties and is a good isolator. It was also determined that the natural composite has properties derived from both banana tree fibers (as thermal properties and mechanical strength) and thermoplastic elastomer latex. This result did not jeopardize the banana fiber’s hygroscopicity. Finally, it is possible to conclude that the material is long-lasting, does not harm the environment, and performs the coating function as expected.
