Effect of Fiber surface treatment and Fiber loading on the properties of Bagasse Fiber–reinforced unsaturated polyester composites
Composites Science and Technology, 2008Co-Authors: Vannaladsaysy Vilay, M Mariatti, R. Mat Taib, Mitsugu TodoAbstract:Abstract Bagasse Fiber is a residue of a sugarcane milling process. In this research, Bagasse Fiber has been used as reinforcing component for unsaturated polyester resin (USP) to open up further possibilities in waste management. The chemical treatments using sodium hydroxide (NaOH) and acrylic acid (AA) were carried out to modify the Fiber properties. The effect of different Fiber treatment and the Fiber content on the composite properties were investigated. At different Fiber loadings, AA treated Fiber composites shows better mechanical properties compared to those of NaOH treated Fiber composites. SEM investigations show that the surface modifications improve the Fiber–matrix interaction. Moreover, the storage modulus of dynamic mechanical analysis (DMA) indicated that NaOH and AA treated Fibers based composites enhance the storage modulus of the composites. From water absorption study, it was observed that the treated Fiber composites show lower water absorption properties compared to those of untreated Fiber based composites.

Weibull Analysis to Characterize the Diameter Dependence of Tensile Strength in Sugarcane Bagasse Fibers
Materials Science Forum, 2020Co-Authors: Verônica Scarpini Candido, Michel Picanço Oliveira, Raissa De Almeida Gouvêa, Amanda Luiza Bezerra S. Martins, Sergio Neves MonteiroAbstract:Fibers obtained from de sugarcane Bagasse are being investigated as possible engineering materials. Their application as reinforcement of polymer composites is of interest due not only to environmental benefits associated with a waste recycling but also to their biodegradable and renewable characterisitics. Since it is known that many lignocellulosic Fibers present a tensile strength inverse dependence with the diameter, this possibility was investigated on Bagasse Fibers. By means of the Weibull analysis, it was found that the thinner the Bagasse Fiber, the greater the strength. Fracture observation of Bagasse Fibers by scanning electron microscopy, indicated possible mechanisms related to this inverse correlation.

Characterization of Epoxy Matrix Composites Incorporated with Sugarcane Bagasse Fibers
Materials Science Forum, 2020Co-Authors: Amanda Luiza Bezerra S. Martins, Verônica Scarpini Candido, Michel Picanço Oliveira, Raissa De Almeida Gouvêa, Sergio Neves MonteiroAbstract:Sugarcane Bagasse is a typical waste generated in the production of sugarcane and ethanol. This agro-industrial waste is commonly used as fuel in the industry boiler for the steam and energy generation. However, part of the Bagasse waste is disposed and may pollute the environment. The Fibers extracted from the sugarcane Bagasse have been considered as addition to polymeric composites. In the present work epoxy composites incorporated with 30% in volume of continuous sugarcane Bagasse Fibers were evaluated in terms of their mechanical properties. As compared to the neat epoxy, the Bagasse Fiber displayed an increase in elastic modulus but a decrease in strength and ductility. The analysis of the composite microstructure by scanning electron microscopy revealed flaws and pores that could justify these preliminary obtained results.

thermal behavior of polyester composites reinforced with green sugarcane Bagasse Fiber
JOM, 2018Co-Authors: Verônica Scarpini Candido, Alisson Clay Rios Da Silva, Sergio Neves MonteiroAbstract:Natural Fibers such as those from sugarcane Bagasse may be obtained as industrial waste products. These Fibers have recently been investigated as low-cost reinforcements in composites for engineering applications, some of which may require exposure to temperatures above ambient. In the present work, Fibers extracted from sugarcane Bagasse were used at up to 30 vol.% as reinforcement in polyester-matrix composites. The thermal behavior of these composites was investigated by thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG) as well as dynamic mechanical analysis (DMA) and differential scanning calorimetry (DSC). TGA/DTG results indicated similar limits of thermal stability at about 200°C for the neat polyester and the Bagasse Fiber composites. The thermal degradation peak at around 370°C was also similar, being attributed mainly to polyester. DSC analysis revealed that Bagasse Fiber incorporation caused only a minor change in the glass-transition temperature. On the contrary, DMA parameters revealed notable changes attributed to effect of the Bagasse Fibers on the viscous stiffness and damping capacity of the polyester.

Toughness of polyester matrix composites reinforced with sugarcane Bagasse Fibers evaluated by Charpy impact tests
Journal of materials research and technology, 2017Co-Authors: Verônica Scarpini Candido, Alisson Clay Rios Da Silva, Noan Tonini Simonassi, Sergio Neves MonteiroAbstract:Abstract The Fibers extracted from the sugarcane Bagasse have been investigated as possible reinforcement for polymer matrix composites. The use of these composites in engineering applications, associated with conditions such as ballistic armor, requires information on the impact toughness. In the present work, Charpy tests were performed in ASTM standard specimens of polyester matrix composites, reinforced with 10, 20 and 30 vol% of continuous and aligned sugarcane Bagasse Fibers, in order to evaluate the impact energy. Within the standard deviation, the composite absorbed impact energy increased with the volume fraction of sugarcane Bagasse Fiber. This toughness performance was found by scanning electron microscopy to be associated with the Fiber/matrix delamination.

Sugarcane Bagasse waste in composites for multilayered armor
European Polymer Journal, 2016Co-Authors: Sergio Neves Monteiro, Verônica Scarpini Candido, Fábio De Oliveira Braga, Lucas Tedesco Bolzan, Ricardo Pondé Weber, Jaroslaw DrelichAbstract:Abstract The residue obtained from sugarcane juice extraction, in sugar and ethanol production, is known as Bagasse. At the industrial mill, Bagasse is either incinerated for steam and power generation or discarded as a waste. The incorporation of Bagasse waste into polymeric composites for ballistic resistant materials was investigated in this study. Plates of epoxy composites reinforced with either raw Bagasse or extracted Bagasse Fibers were characterized. The 30 vol% Bagasse composites were selected as a second layer, backing a front ceramic, in multilayered armors against 7.62 mm ammunition. Ballistic performance of composites was compared to Kevlar™ plates used in commercial multilayered armor systems. Results of ballistic tests indicated that multilayered armors with Kevlar™ and Bagasse Fiber composites satisfied the National Institute of Justice (NIJ) norm, and displayed similar depths of indentation in a clay witness. By contrast, the armor with raw Bagasse composite demonstrated worse performance, with nearly two times deeper indentations, some of which exceeded the NIJ limit. Economical analysis revealed that armor with Bagasse Fiber composite is nearly 180% less expensive than a corresponding armor with Kevlar™. Therefore, it is shown for the first time that composites reinforced with Fibers extracted from sugarcane Bagasse (a large scale worldwide generated waste) could replace Kevlar™ in multilayered armor systems making them cheaper and more sustainable.

The effect of Bagasse Fibers obtained (from rind and pith component) on the properties of unsaturated polyester composites
Materials Letters, 2008Co-Authors: M MariattiAbstract:Abstract In the present study, two major component of Bagasse, namely rind (outer part) and pith (inner part) were used as reinforcement in unsaturated polyester (USP) composites. The Bagasse Fiber filled USP composites were produced by vacuum bagging method and the volume percentage of Fiber was varied at 0%, 5%, 10% and 15%. Characterizations such as flexural, impact and water absorption were carried out to measure the properties of the composites. Based on the result, it was found that the rind Fiber composites produced higher flexural and impact properties, and lowered water absorption rate compared to inner Fiber composite. In short, the flexural, impact and water absorption properties of Bagasse composites are governed by the two major component of Bagasse; rind and pith.

tunable electromagnetic interference shielding ability in a one dimensional Bagasse Fiber polyaniline heterostructure
ACS Applied Polymer Materials, 2019Co-Authors: Yang Zhang, Zhangjing Yang, Ying YuAbstract:Development of highly efficient electromagnetic interference (EMI) shielding materials with tunable properties is essential for the modern electronics industry against severe electromagnetic pollution. Herein, a series of novel heterostructured Bagasse Fiber/polyaniline (BF/PANI) composites are successfully synthesized via a facile in situ polymerization method and both their EMI shielding effectiveness (SE) and mechanisms were analyzed experimentally and theoretically. The results show that the conductivity and EMI shielding properties of BF/PANI composites can be tailored by adjusting the component, microstructure, and electromagnetic parameter, which can be easily tuned by modulating the weight ratio of aniline monomer and BF. More significantly, the BF/PANI heterostructures exhibit remarkable enhanced EMI shielding capabilities compared with the pristine PANI. The BF/PANI heterostructure prepared with an aniline volume of 7 mL shows an electrical conductivity of 6.07 S·cm–1 and the best EMI shielding ...

a novel polyaniline coated Bagasse Fiber composite with core shell heterostructure provides effective electromagnetic shielding performance
ACS Applied Materials & Interfaces, 2017Co-Authors: Yang Zhang, Ying Yu, Lele ChengAbstract:A facile route was proposed to synthesize polyaniline (PANI) uniformly deposited on Bagasse Fiber (BF) via a one-step in situ polymerization of aniline in the dispersed system of BF. Correlations between the structural, electrical, and electromagnetic properties were extensively investigated. Scanning electron microscopy images confirm that the PANI was coated dominantly on the BF surface, indicating that the as-prepared BF/PANI composite adopted the natural and inexpensive BF as its core and the PANI as the shell. Fourier transform infrared spectra suggest significant interactions between the BF and PANI shell, and a high degree of doping in the PANI shell was achieved. X-ray diffraction results reveal that the crystallization of the PANI shell was improved. The dielectric behaviors are analyzed with respect to dielectric constant, loss tangent, and Cole–Cole plots. The BF/PANI composite exhibits superior electrical conductivity (2.01 ± 0.29 S·cm–1), which is higher than that of the pristine PANI with 1....
