4. Estrategia para la optimización de un compuesto de caucho con aceite de soja utilizando diseños de experimentos
ABSTRACT When a rubber component is made, is necessary to start from a “rubber compound” which may be composed of one or more polymers and various additives or fillers. The development of an elastomer mixture to produce a compound with a specific end-use is complicated in the field of rubber technology. Therefore, the successful development of a compound

5. DYNAMIC TRACTION OF A MECHANIZED SET BASED ON TECHNICAL AND OPERATIONAL PARAMETERS
ABSTRACT The objective of this study was to evaluate and model the traction performance parameters of a tractor 4x2 FWD, according to the tractor speed, the internal pressure and the type of tires construction. For each type of tire construction was assembled an experiment in which we evaluated the influence of internal pressures of the front and rear tires

6. Influence of SEBS-MA and SBS compatibilizers on properties and morphology of blends of polystyrene/rubber residue (SBRr) from the footwear industry
Abstract The reuse of rubber waste is very important today, both to reduce the harmful effects on the environment, and to reduce the cost of new material development. Considering that most of the studies reported in literature refer to the reuse of tire waste, this article aims to evaluate the influence of styrene-butadiene-styrene (SBS) and styrene-(ethylen

7. The effects of porosity in friction performance of brake pad using waste tire dust
Abstract This research is focused on the effect of porosity on the friction-wear properties of automotive brake pads. Waste Tire Dust (WTD) was used as a new friction material in brake pads. Newly formulated brake pad materials with five different components have been produced by conventional techniques. In the experimental studies, the change of the frictio

8. Evaluation of the effect of the incorporation of rubber tire waste particles on the properties of PP, HIPS and PP/HIPS matrices
In recent years, the consumption of plastics has been increasing and as consequence, the waste generated has also increased. Rubber tire (RT) waste is another residue which causes significant problems to society. In view of the considerable amounts of RT waste generated, this study aimed to evaluate the influence of the incorporation of RT particles into pos

9. Produção de hidrogênio e etanol em reator anaeróbio de leito fluidizado: avaliação do desempenho de três materiais suporte em diferentes condições operacionais
Hydrogen and ethanol production using microorganisms is a promising area of technological development from a wide variety of renewable and alternative to this production is the use of anaerobic fluidized bed reactor (AFBR). One of the factors that most influence the performance of the AFBR is the material support, which must provide abrasion resistance, poro

10. Contribuição para calibração de curva de evolução de afundamentos em trilha de roda de revestimentos asfálticos com utilização de resultados obtidos de simulador de tráfego em escala real. / A contribution to the calibration of performance curves for the prediction of permanent deformation in asphalt pavements using the results obtained from a large scale mobile traffic simulator
Permanent deformation, or rutting, is a critical type of pavement distress given that it is directly associated with transportation costs, due to a reduction of the ride quality, and user safety, due to poor driving conditions or water build-up during rainy periods that affect the tire-pavement interaction. In the case of pavements of highways belonging to c

11. Fibras de aço em concreto de cimento Portland aplicados a pavimento / Portland cement concrete with steel fibers used in pavement
The objective of this research is to contribute for the Portland cement concrete study with addition of fibers used on pavements. This research studied the results of different dosages using steel fibers in order to optimize their use as well as direct care during mixing and application. The Portland cement concrete pavement has been acting with an important

12. ANÁLISE DE DESEMPENHO EM TRAÇÃO DE RODADO SIMPLES E DUPLO EM UM TRATOR AGRÍCOLA / ANALYSIS OF TRACTION PERFORMANCE OF SINGLE AND DUAL TIRES IN AN AGRICULTURAL TRACTOR
A major problem of agricultural tractor during several operations in which it is used is the difficulty of working in various moisture conditions and soil types affect your ability to traction force, slip and fuel consumption. What has been observed is that with increased contact surface between the tire of the tractor and the ground, there is the possibilit
