A influência de diferentes tratamentos das fibras de sisal nas propriedades dos compósitos de borracha nitrílica/fibras de sisal, e borracha nitrílica/carbonato de cálcio/fibras de sisal foi investigada. Os compósitos, com fibras curtas aleatoriamente distribuídas, foram processados em moinho de dois rolos e caracterizados através de ensaios mecânicos de resistência à tração, microscopia eletrônica de varredura (MEV), análise por termogravimetria (TG) e calorimetria exploratória diferencial (DSC). O tratamento de mercerização das fibras levou a uma maior adesão na interface fibra/matriz. O uso combinado de 67 pcr de carbonato com 33 pcr de fibras de sisal mercerizadas produziu um compósito com aumento significativo no módulo de elasticidade e sem perda da resistência à tração de ruptura. Os resultados da análise térmica mostraram que os compósitos são termicamente estáveis até cerca de 300 °C. Os materiais obtidos possuem uma boa relação custo/benefício tornando promissora sua utilização.

“…Many researchers have made efforts for preparing natural carbon black from agricultural by-products such as coconut shell, 4 oil palm shell, 5 and bamboo. 6 The huge majority of carbon black finds uses as reinforcement in polymer industries for advanced application and to improve the performance of the matrix 7 over other established materials. The properties of carbon black used in the composites mainly depend on the origin, processing conditions, and chemical treatments.…”

This article describes the development of new carbon black material from agricultural waste (wood apple shells) by using pyrolysis method at various carbonization temperatures (400, 600, and 800 C) and used as reinforcement in polymer composites.The wood apple shell carbon black (WAS-CB) particulates are characterized by proximate analysis, energy dispersive spectroscopy (EDS), and scanning electron microscope (SEM). Results showed that due to increases in carbonization temperature the percentage of carbon improved in the carbon black particles. Furthermore, various tests were performed to determine the effect of new carbon black material on the mechanical properties of composite at different filler loading. The results indicated that mechanical properties like tensile strength, tensile modulus, flexural strength, and flexural modulus are improved as the increase in the carbonization temperature and filler loading. The filler-matrix bonding was analyzed by SEM.

“…Fiber-reinforced polymer composites are now used as alternative low cost materials for structural and nonstructural applications, such as automotive applications, packaging, building products, furniture, and consumer goods. In the past, a diversity of short fibers was merged into natural rubber, and their reinforcement was discussed [4][5][6][7][8][9]. It was found that they did not provide a similar level of reinforcement compared to carbon black and silica.…”

In this work, composites made from styrene-butadiene rubber and short fibers were prepared by mixing and investigated. The influence on the vulcanization process and tensile strength properties has been studied and compared with compounds filled with carbon black. The presence of fibers gave shorter curing time and led to a slight increase in tensile strength but decreased the elongation at break of the compound.
