1. Development and characterization of composite materials for production of composite risers by filament winding
Industry has been challenged to provide riser systems which are more cost effective and which can fill the technology gaps with respect to water depth, riser diameter and high temperatures left open by flexibles, steel catenary risers (SCRs) and hybrid risers. Composite materials present advantages over conventional steel risers because composite materials a

2. InspeÃÃo da degradaÃÃo nos isoladores de compÃsito de linhas de transmissÃo atravÃs de ensaios nÃo destrutivos
Na presente dissertaÃÃo, nove unidades de isoladores de compÃsito, das quais oito unidades foram retiradas da linha de transmissÃo de 230 kV da Chesf apÃs um perÃodo de aproximadamente 10 anos em operaÃÃo, prÃximas ao local de ocorrÃncia de fratura frÃgil e cobertas com camadas de poluentes, foram inspecionadas atravÃs de radiografia digital empr

3. Blindagem balÃstica de compÃsito polimÃrico contra o vandalismo e proteÃÃo UV para cadeias de isoladores de vidro em linhas de transmissÃo
The aim of this study was to induce the UV absorption of soda-lime silica glasses by gamma irradiation, as well as to select and evaluate the mechanical and electrical properties and also the microstructure of the polycarbonate (PC), with and without heat treatment, and the glass fiber reinforced epoxy composite, to make a prototype for transmission lines co

4. Estudo de um novo compósito madeira-resina poliuretana para o desenvolvimento de um isolador híbrido / Study of a new wood-polyurethane resin composite for the development of a hybrid insulator
This work aims at the study of the application of reforestation wood, of Pinus Taeda species, impregnated with polyurethane resin derived from the castor-oil plant as a new product for the manufacture of hybrid electric insulators. This research possesses a great ecological appeal, as the wood-polyurethane resin composite derived from reforestation wood and

5. The effects of fillers on polyurethane resin-based electrical insulators
The increasingly widespread use of polymeric insulators in vehicle distributors and transmission systems has led to an ongoing quest for quality and low costs. This quest has, in turn, resulted in improved performance and cost benefits, brought about by the use of new polymeric and composite resins. Occasionally, however, while some properties are improved,

6. Determinação da condutividade termica e da resistencia mecanica em argamassa leve
This work deals the determination of the thermal conductivity and the mechanical strength in light mortar with soft aggregate, evidencing the features term-insulators of the composite and analysis of the main aspects of the cement composite, concerning to its mechanical characteristics. The procedure adopted for determination of thermal conductivity, has the
