Resumo
Thinking about the growing search for materials that can improve the efficiency of thermal insulations, and that do not cause aggressions to the environment, we decided to use the leaf of the carnauba as an alternative reinforcement in composites of thermal insulation. The composite is formed by natural fibers of leaves of the carnauba, that possesses good physicochemical properties to work as a thermal insulation and the minerium kaolin , that is characterized for being chemical inert and possesses low thermal conductivity. Tests were made to evaluate the thermal properties such as conductivity and resistance on a pressed block of pure kaolin , then there were made composites in formulations of 10%, 30% and 50%, this value indicates the percentage of the fiber mass of the carnauba powder per total mass of the composite, these variations were made so the tests could reveal how the increase of carnauba affected the thermal properties of the insulation.
