1. Surface treated fly ash filled modified epoxy composites
Fly ash, an inorganic alumino silicate has been used as filler in epoxy matrix, but it reduces the mechanical properties due to its poor dispersion and interfacial bonding with the epoxy matrix. To improve its interfacial bonding with epoxy matrix, surface treatment of fly ash was done using surfactant sodium lauryl sulfate and silane coupling agent glycidox

2. Estudo do efeito da dopagem da alumina com CÃrio em catalisadores Pt/CeZrO2/Al2O3 na reaÃÃo de oxidaÃÃo parcial do Metano
The transformation of methane into liquid fuels has drawn a lot of attention in the last years due to both economical and environmental concerns. Currently, the main route to obtain synthesis gas from methane is the steam reforming. The major problems associated with this route are the high temperatures and pressures required. Nowadays, the partial oxidation

3. UMA FORMULAÇÃO DE ELEMENTOS FINITOS AXISSIMÉTRICOS PARA ANÁLISE DE TUBOS LAMINADOS EM MATERIAIS COMPÓSITOS / AN AXISYMMETRIC FINITE ELEMENT FORMULATION FOR THE ANALYSIS OF LAMINATED COMPOSITE TUBES
The use of composite materials in structures has grown in the engineering practice due to its characteristics, of high strength, low density and a good stability to thermal effects. A class of composites, the fibrous laminates, is generally used in tubes subjected to many types of loadings as internal and/or external pressure, traction, torsion, temperatures

4. STRESS AND STRAIN ANALYSIS OF COMPOSITE SHELLS WITH GENERAL GEOMETRIES / ANÁLISE DE TENSÕES E DEFORMAÇÕES EM CASCAS COMPOSTAS DE GEOMETRIAS ARBITRÁRIAS
Este trabalho apresenta a modelagem teórica e correspondente solução numérica, associada ao problema de tensões e deformações em cascas compostas de geometrias arbitrárias, submetidas a carregamento térmico e/ou de pressão. A casca composta é constituída de uma camada viscoelástica reforçada por outras duas elásticas. Apresentam-se as hipótes

5. AXIAL AND BENDING LOADING OF STRUCTURES CAUSED BY THERMAL DIFFERENCES / SOLICITAÇÃO DE HASTES A FLEXÃO E ESFORÇO AXIAL PROVOCADOS POR DIFERENÇAS TÉRMICAS
Different types of structures submitted to thermal loadings under different conditions of support are studied in this work, with the purpose of analysing the thermal Ratchet Mechanism. This phenomena is na important criteria of safety of nuclear power systems. A first model was used to simulate the bahavior of a structure free of bending, submitted to temper
