1. Quantification by FT-IR (UATR/NIRA) of NBR/SBR blends
Abstract Rubber blends are important materials in automotive industry, as well as in other sectors. However, there are implications when suitable use of a polymer in an artifact is not made. In the automotive area, for example, the use of an elastomer without the fuel resistance requirement would result in component degradation, potential fuel leakage, and

2. FT-IR methodology (transmission and UATR) to quantify automotive systems
Abstract When using Fourier transform infrared spectroscopy (FT-IR) under the qualitative aspect for characterization of polymer blends, often a simple identification of each one of the existing polymers in the blend does not justify the material failure since different amounts of each component may result in different mechanical properties, which should be

4. Parametric Modal Study and Optimization of the Floor Pan of a B-Segment Automotive Using a Hybrid Method of Taguchi and a Newly Developed MCDM Model
Abstract The floor pan is an important component that connects the front and rear segments of the automotive underbody structure. Global stiffness and NVH characteristics of BIW are highly dependent to shape, thickness and mass of the body panels and could be evaluated by modal characteristics of these panels. The feeling of solidness and comfort of passenge

8. Fatigue properties and micromechanisms of fracture of an AlSiMg0,6 cast alloy used in diesel engine cylinder head / Propriedades de fadiga e micromecanismos de fratura da liga de aluminio-silicio AlSi7Mg0,6 utilizada em cabeçote de motor diesel
The increase usage of casting aluminum-silicon alloys in the automotive industry is due to reduce weight, fuel consumption, and emissions level. This includes the aluminum-silicon cast alloy EN AlSiMg0.6 (ASTM A357.0) which is used to make Diesel engine cylinder head. It is important to know the impact on the integrity and reliability of this component in th

11. Perovskitas preparadas pelo método do citrato como catalisadores para a reação de redução de NO com CO / Perovskites prepared by citrate method like catalysts to NO with CO reduction reaction
One of the biggest problems that man has found because of his development is the pollution. The main responsible for atmospheric pollution are the automotive vehicles and to minimize the pollution produced by them it has been necessary to use catalysts. These catalysts, called "three way catalysts", actually have noble metals like active sites, what takes up
