A biomassa é todo o material orgânico que, quando queimado, libera alguma forma de energia. Para utilização da biomassa é necessário conhecer o seu poder calorífico que está diretamente relacionada com o teor de umidade no combustível. O objetivo deste estudo é determinar o poder calorifico superior das espécies de Eucalyptus grandis e Hevea brasil...
Biomass is all organic material, which when burned, releases some form of energy. In
order to characterize biomass burning is becomes necessary to know its calorific value that is
directly related to the moisture content on the fuel. The objective of this study is to determine the
high heating value from particles of the species Eucalyptus grandis...
1 Abstract-The utilization of composite materials in various engineering sectors has gained significant prominence due to their unique characteristics. However, owing to their inherent heterogeneity, these materials often exhibit nonlinear and unpredictable behaviors. Consequently, the finite element method has seen a growing application as an inva...
In the present work a fiber metal laminate (FML) of three aluminum sheets interspersed with eight layers of glass fiber reinforced epoxy was used. The processes were carried out using 4000 and 8000 rpm and a 0.05; 0.10 and 0.20 feed in mm/rev with a coated carbide drills (TiAlN) with Ø4.8mm. With the found results, it could be stated that the thrus...
The use of fiber metal laminates (FML) in aeronautics components has been increased in the last years, mainly due to the gain in mechanical properties combined with low specific mass. However, in the assembly of these materials on the structures to which they will be attached, mechanical screwing is still the main method used, which requires the pe...
Bolted joints are the most common form of union of the components in an airplane, with drilling being the most used process in obtaining the holes. However, this process can cause several defects, so the parts produced can go to the assembly line with some defects. Aim of this manuscript was to analyze the influence of spindle speed and the feed in...
The use of composite materials in several sectors, such as aeronautics and automotive, has been gaining distinction in recent years. However, due to their high costs, as well as unique characteristics, consequences of their heterogeneity, they present challenging gaps to be studied. As a result, the finite element method has been used as a way to a...
The objective of this research was to study the machining of superalloy VAT32® using alumina-based ceramic tool without cutting fluid, applying different machining parameters to evaluate the surface finish of parts, vibration and main wear of tools. For this, a turning process with a linear trajectory of 30 mm was performed, in which were collected...
The objective of the research was to evaluate the efficiency of alumina-based cutting tool (Al2O3), machining of superalloy VAT 32®. Turning tests were made at 30 mm linear conducting passage measurement of roughness and the wear and damage to the tool. The tests were performed using shear rates of 270, 280 and 300 m/min, feed rates of 0.10 and 0.1...
The economic exploitation of rubber tree (Hevea brasiliensis) usage is primarily directed toward latex extraction. After the productive life of the rubber tree forest, the managed area is harvested for planting reformulation. The harvested wood is most often used for energy generation purposes. The aim of this work was to study the feasibility of u...
The objective of the present work was to study the use of bamboo foils as structural reinforcement for MDP wooden panels. Four wooden panels of homogeneous layer were produced using particles of GT1 and RRIM 600 clones of Hevea brasiliensis (rubber tree), and glued with urea-formaldehyde resin (UF). These panels were also overlaid with foils of Phy...
This work aimed to study the feasibility of using castor oil-based polyurethane (PU) resin, and rubberwood for the production of particleboards. Multilayer panels were produced using particles taken from RRIM 600 and GT1 clones of Hevea brasiliensis trees. Urea-formaldehyde (UF) and PU were used for bonding the particles. Physico-mechanical charact...
