Resumo: | The growing global energy demand requires solutions that improve energy efficiency. The civil construction sector is responsible for a large part of this consumption. In this context, the objective of this work was to confer thermal energy storage properties to a jute fabric, to be applied in civil construction as reinforcement for cement matrices. In order to do this, a method to incorporate a phase change material (PCM) into the tissue was developed. Jute textiles were immersed in liquid PCM, and then coated with a polymer by immersion in a polymeric suspension. Carboxylated styrene-butadiene copolymers (with or without the addition of 5% zinc oxide) and carboxylated nitrile rubber were evaluated. The mechanical, morphological and chemical characterization of the jute fabric containing PCM was carried out. The results verified the containment of PCM in the capillary pores of the textile with all treatments, but with some damage to its mechanical properties. The treatment with carboxylated nitrile rubber provided better mechanical properties, in addition to forming a thinner and lighter coating layer. The fabric containing PCM was used in the manufacture of a laminated composite called textile reinforced concrete. The evaluation of the mechanical and thermal properties revealed that the presence of PCM causes a negative effect on the mechanical properties of the material, but it was possible to verify the effect of thermal energy storage conferred by the PCM, delaying temperature variations of the composite in the temperature range of the physical state transition of the PCM. It was concluded that the proposed method was valid for the production of cementitious composites reinforced with vegetable fibers with thermal energy storage properties. |

O setor de construção civil é responsável por grande parte deste consumo. Neste contexto, o objetivo deste trabalho foi conferir propriedades de armazenamento de energia térmica a um tecido de juta, para ser aplicado em construção civil como reforço para matrizes de cimento. Para isso, foi desenvolvido um método para incorporar um material de mudança de fase (PCM) ao tecido. A juta era imersa no PCM líquido, e em seguida era realizado o revestimento com um polímero através de imersão em uma suspensão polimérica. Foram avaliados os copolímeros de estireno-butadieno carboxilado (com ou sem a adição de 5% de óxido de zinco) e a borracha nitrílica carboxilada. Foi realizada a caracterização mecânica, morfológica e química do tecido de juta contendo PCM. Os resultados verificaram a contenção de PCM nos poros capilares do tecido com todos os tratamentos, porém com certo prejuízo nas propriedades mecânicas do mesmo. O tratamento com borracha nitrílica carboxilada conferiu melhores propriedades mecânicas, além de formar uma camada de revestimento mais fina e leve. O tecido contendo PCM foi utilizado na fabricação de um compósito laminado denominado concreto reforçado com têxtil. A avaliação das propriedades mecânicas e térmicas revelaram que a presença do PCM causa um efeito negativo nas propriedades mecânicas do material, porém foi possível verificar o efeito de armazenamento de energia térmica conferido pelo PCM, atrasando variações de temperatura do compósito na faixa de temperatura de mudança de estado físico do PCM. Concluiu-se pela validade do método proposto para a produção de compósitos cimentícios reforçados com fibras vegetais com propriedades de armazenamento de energia térmica.Universidade Federal de LavrasPós-Graduação em Engenharia de BiomateriaisUFLAbrasilDepartamento de Ciências FlorestaisFerreira, Saulo RochaMankel, ChristophKoenders, EduardusGuimarães, Túlio Caetano2023-03-10T20:26:34Z2023-03-10T20:26:34Z2023-03-102023-01-17info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfGUIMARÃES, Túlio Caetano.
