Natural lignocellulosic fibers (NLFs) have been investigated, especially in the past decades, as promising reinforcement composite materials for engineering applications. The interest regarding use of NLFs is associated with advantages such low density and high mechanical strength well toxicity cost-effectiveness. In addition, are also considered environmentally friendly materials. Indeed, they biodegradable obtained from renewable resources. this paper, a relatively unknown Amazonian NFL,...
Mechanical properties of composites reinforced with lignocellulosic fibers have been researched in recent decades. Jute and mallow are reinforcement alternatives, as they can contribute to increase the mechanical strength composite materials. The present work aims predict Young's modulus application continuous aligned be applied polyester matrix. Fibers were manually separated then arranged Composites addition 5, 15, 25 vol% jute produced by vacuum-assisted hand lay-up/vaccum-bagging...
Natural lignocellulosic fibers (NLFs) have in recent decades appeared as sustainable reinforcement alternatives to replace synthetic polymer composite material applications. In this work, for the first time, periquiteira (Cochlospermum orinocense), a lesser known NLF from Amazon region, was analyzed its density and, by X-ray diffraction (XRD), calculate crystallinity index well microfibrillar angle (MFA), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR),...
With the advancement of Additive Manufacturing and its applications in various industrial segments, it becomes increasingly important to investigate processability parameters associated with nano-reinforcement. This study examines influence infill parameters, such as patterns (hexagonal, triangular concentric), shape (solid honeycomb) concentrations by mass Carbon Nanotubes (CNTs) at 1.0 wt% 2.0 on mechanical compression properties 3D printed material. In this sense, nanocomposites based...
Bone tissue is one of the most important in human body. In this study, scaffolds poly (lactic acid) PLA reinforced with hydroxyapatite (HA) and carbon nanotubes (CNT) were manufactured, evaluating their mechanical biological properties. HA was synthesized by wet method characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). The produced using additive manufacturing optical microscopy, SEM, thermogravimetric analysis (TGA),...
The Amazonian region of South America is known for its diversified number plants from which food, medicine, wood and fibers have, since long time, been produced by local natives. A typical example the guarumã ("guaruman"as suggested English spelling) scientifically identified as Ischinosiphon koem, an abundant plant found in low lands alongside rivers state Para Brazil. Fibers extracted stem guaruman are used ropes baskets owing to their strength. In present work, possibility applying...
