1. Evaluation of Dynamic Mechanical Properties of Fique Fabric/Epoxy Composites
The fique is a plant typical of the Colombian Andes, from which relatively common items are fabricated. One of these is woven fabric extensively applied in sackcloths. The mechanical strength of fique fabric have motivated recent investigations on possible reinforcement of polymer matrix composites. For this purpose its thermo-mechanical behavior was unveile

2. Avaliação da utilização da pós cura nas propriedades térmicas e mecânicas de um sistema epóxi de cura à temperatura ambiente
RESUMO Neste trabalho, uma resina epóxi de cura a temperatura ambiente foi submetida a ciclos térmicos de pós cura para verificar as alterações nas propriedades térmicas e mecânicas finais do material. As amostras foram obtidas por vazamento em molde metálico e os ciclos de pós cura foram realizados a 75°C, 90°C, 110°C por uma hora e um ciclo de

3. Análisis comparativo de las propiedades mecánicas de un material compuesto reforzado con fibras de carbono y las de su matriz polimérica de resina epóxica
ABSTRACT In recent years composite materials have been developed for different applications in engineering areas. This paper first presents the tensile properties of a polymer, in this case an epoxy resin, to be used as the matrix of a fiber reinforced composite material. A study of the mechanical properties is presented, which was carried out by performing

4. Cardanol-based thermoset plastic reinforced by sponge gourd fibers (Luffa cylindrica)
Abstract A growing global trend for maximum use of natural resources through new processes and products has enhanced studies and exploration of renewable natural materials. In this study, cardanol, a component of the cashew nut shell liquid (CNSL), was used as a building block for the development of a thermosetting matrix, which was reinforced by raw and mod

6. Tensile Behavior of lignocellulosic reinforced polyester composites: Part III coir fiber
The fiber extracted from the husk of a coconut fruit, known as coir fiber, has been extensively investigated as a second phase incorporation into polymer composites. The moderate strength of the coir fiber usually does not represent reinforcement to relatively strong thermoset matrices such as polyester, epoxy and phenolic. However, a selection of thinner co

7. Sodium lignosulphonate as agent of modification of lignocellulosic fiber surface and formulation of phenolic thermoset / Lignosulfonato de sódio como agente de modificação da superfície de fibras lignocelulósicas e da formulação de termorrígido fenólico
Due to the great current interest in biocomposites because of both the use of lignocellulosic fibers as reinforcers of polymer matrices and the production of matrices prepared from renewable raw material, this study has sought to improve the properties of phenolic thermosets using sodium lignosulphonate as a macromonomer, and the insertion of sisal fibers, e

9. Aplicação de redes neurais no processo de filament winding
Polymer composites or reinforced plastics are materials made with a polymer matrix and a reinforcement. Nowadays polymer composite market is one of the most promising, because of the many advantages of these materials such as weight saving, corrosion and temperature resistance and manufacturing cost reduction, when compared to conventional engineering materi
