1. X-ray Scattering and Chemometrics as Tools to Assist in the Identification of Gunshot Residues by Wavelength Dispersive X-ray Fluorescence Spectrometry
Wavelength dispersion X-ray fluorescence spectrometry (WDXRF) is a non-destructive technique and therefore attractive for gunshot residues (GSR) analysis. It is well known for determination of inorganic constituents of samples. However, X-ray scattering region spectral data is not commonly used, although it may provide information about organic constituents

2. 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

3. Determinação do raio efetivo em pastilhas circulares de freios a disco em tribômetro / Determination of effective radius in circular pads of disk brakes in tribometer
Este trabalho visa dar continuidade à linha de pesquisa com materiais de fricção utilizando um equipamento especificamente desenvolvido para esse fim. O equipamento encontra-se em condições de funcionamento, porém a medição do raio de aplicação da força é indireta, gerando erros em sua medição. Determinou-se, de forma analítica, o raio efetivo

4. Analysis of wear in organic and sintered friction materials used in small wind energy converters
Wind energy converters of small size used in isolated units to generate electrical energy must present low maintenance cost to such facilities economically viable. The aspect to be analyzed in cost reduction is the brake system, since in isolated systems the use of brake is more frequent reducing the brake pads life time. This study aims at analyzing the wea

6. Development of asbestos-free friction lining material from palm kernel shell
Friction materials are applicable for braking and transmission in various machines and equipment. Their composition keeps changing to keep pace with technological development and environmental/legal requirements. For more than 80 years asbestos has been used as a friction material because of its good physical and chemical properties. However, due to the heal

7. Estudo de variáveis de composição e processo para controle da compressibilidade
Brake pads for automotive brake systems represent one of the most complex composite materials since they contain many components with widely varying physical and chemical properties. This multiphase nature is necessary to satisfy a wide variety of performance related demands. Processing conditions also have a major influence on the properties of these comple

8. Evaluation of the Brazilian brake pads performance / Avaliação do desempenho de pastilhas automobilisticas nacionais
Automotive brake systems are mainly friction based. The world tendency is toward using disc brakes instead of drum brakes, which are usually installed in the rear wheels. The increase in the performance of automotive vehicles and the changes in the dynamic characteristics have conducted to more efficient brake systems. The expansion of the brake pads market

10. Comparação de desempenho dos sistemas de freio de atrito tipo sapatilha-disco e sapata-roda para veiculos ferroviarios de carga
The objective of this work was to obtain and compare the parameters of the railway friction brakes, both shoe-wheel and pad-disk types, verifying the technical possibility of the pad-disc system to be used in replacement to the conventional shoe-wheel system for freight vehicles, maintaining the safe conditions to components integrity. The conditions were ex
