Commercial glass fiber reinforced-vinyl ester resin composite pipes used in onshore and offshore utilities were exposed to the action of fluids that could normally come into contact with them during their service life, namely: salt water, biodiesel and a mixture of water and oil. The influence of these fluids upon the flexural properties and parallel-plate loading behavior of the composites was evaluated. The results of the mechanical tests point out that physical aging was the main phenomenon, and that it causes a reduction of stiffness of around 20-30% – at the parallel-plate test – and a decrease of toughness of up to 40% – at the flexural test. The results of the flexural tests were very dependent of the inhomogeneous microstructure of the commercial composite analyzed.

O artigo teve como objetivo compreender a visão sobre o lazer e o entendimento que os idosos possuíam sobre os seus benefícios, dado o quadro de ociosidade dessa população. Foi utilizada uma amostra de sujeitos residentes na cidade de Bauru-SP, com idade igual ou superior a cinqüenta anos, de ambos os sexos e de classe desfavorecida economicamente. Utilizou-se de pesquisa bibliográfica, documental e de campo. Foi desenvolvido um projeto de intervenção que visou a educação para o lazer. Chegou-se a conclusão que são necessárias políticas públicas e profissionais qualificados para a construção de projetos e de equipamentos que expandam o Lazer, difundindo-o e atingindo as pessoas da terceira idade desde fases anteriores da vida. Com materiais simples e de baixo custo, no projeto de intervenção, se alcançou o lazer-educação e a educação para o lazer de forma satisfatória.

The article aimed to understand the concept of leisure and understanding that older people have about their benefits to the quality of life as part of the idleness of the population. We used a sample of subjects living in the city of Bauru, SP, aged less than fifty years, of both sexes and economically disadvantaged class. It was used in literature, documentary and field. We developed an intervention project that aimed to education for leisure. It was the conclusion that public policies are necessary and qualified professionals for construction projects and equipment to expand the Recreation, spreading it and reaching the people of old age since previous stages of life. Materials with simple and low cost, the project of intervention, it reached the recreation-education and education for leisure satisfactorily.
