Cellulose fibers were isolated from sugarcane bagasse in three stages. Initially was subjected to a pre-treatment process with hydrolyzed acid eliminate hemicellulose. Whole cellulosic thus obtained then two-stage delignification and finally bleaching process. The chemical structure of the resulting cellulose studied by Fourier Transform Infrared (FTIR) spectroscopy. Scanning Electron Microscopy (SEM) X-ray diffraction (XRD) used analyze effects hydrolysis, delignification, on fibers. Two...
Two major obstacles to utilizing polyhydroxybutyrate (PHB)-a biodegradable and biocompatible polymer-in commercial applications are its low tensile yield strength (<10 MPa) elongation at break (~5%). In this work, we investigated the modification of mechanical properties PHB through use a variety bio-derived additives. Poly(lactic acid) (PLA) sugarcane-sourced cellulose nanocrystals (CNCs) were proposed as reinforcing elements, epoxidized canola oil (eCO) was utilized green plasticizer. Zinc...
This study focused on the effects of three different sets curing conditions creep properties epoxy resin composites reinforced with unidirectional sisal fibers: (i) at room temperature, followed by postcuring 120°C in an oven; (ii) oven 100°C for 4 h; and (iii) accelerator a ratio 100:38:1 temperature without postcuring. The sisal/epoxy [0°] composite cured presented highest tensile strength, whereas superior resistance long-term performance. scanning electron microscopy images confirmed...
This work describes the surface treatment of coconut fiber and its application in composite materials for reinforcement polypropylene. Before testing materials, susceptibility to chemical was characterized by exposure following: (1) hot water; (2) aqueous NaOH 2% (w/v); (3) a sequence treatments water, extran 20% (v/v), acetone/water 1:1 10% (w/v).The efficiency each evaluated Fourier transform infrared spectrometry analysis, indicating reduction C=O peak. Besides that scanning electron...
Biofuels have been extensively explored and applied in the Brazilian market. In Brazil, ethanol biodiesel are produced on an industrial scale. Ethanol is commercialized used engines both hydrated form (96% °GL) anhydrous form, mixed with gasoline at a proportion of up to 25% by volume. turn, blended diesel 5% Thus, goal use biofuels contribute mitigation greenhouse gases other pollutants emitted into atmosphere during burning. This article describes some recent developments characterization...
This study investigated the influence of surface treatment curaua fibres (Ananas erectifolius) on morphological, thermal and mechanical properties polyester composites when treated (10 wt-%) were added. The following agents assessed: 10% Ba(OH)2, 14% Ca(OH)2, 5% NaOH, KOH silane. treatments removed amorphous components, thereby increasing crystallinity fibres. Among alkali treatments, gave highest index (67.09%), Ca(OH)2 had best tensile strength (19 MPa) resulted in composite stability...
