O presente trabalho tem como objetivos levantar, analisar e sintetizar as principais políticas de incentivo que vêm sendo empregadas para promover o uso das fontes de energia renováveis para a geração distribuída no país e avaliar o conteúdo da Portaria INMETRO n° 168/2015que trata da certificação de aerogeradores. Além disso, este trabalho também busca uma resposta ao questionamento: por que a micro e minigeração eólica distribuída não vem se desenvolvendo tanto quanto a solar? A necessidade e importância de se estudar esse tema está justamente nas recentes políticas regulatórias e nos incentivos públicos-fiscais, que abrem as portas para o mercado de pequenos aerogeradores, em vias de crescimento no Brasil. De fato, a aprovação da Regulamentação Normativa (REN) n° 482/2012aprimorada pela REN n° 687/2015pela Agência Nacional de Energia Elétrica (ANEEL), que lançou as condições para o acesso de micro e minigeração distribuídas ao sistema de compensação de energia elétrica e que constitui um marco para a geração distribuída no país, ratifica essa afirmativa. Os resultados do trabalho mostrarão a viabilidade da mini e microgeração distribuídas a partir dos auxílios das políticas de incentivo, e esboçarão um cenário atual do Brasil quanto à certificação dos aerogeradores de pequeno porte nacionais e importados, evidenciando as normas que não foram adotadas na Portaria citada e o impacto delas na segurança do consumidor e na garantia da qualidade do produto.

In addition, this work also seeks an answer to the question: why is the distributed micro and mini wind generation not developing as much as the solar one? The need and importance of studying this theme is precisely in the recent regulatory policies and public-tax incentives, which open the door to the market for small wind turbines, which are on the rise in Brazil. In fact, the approval of Normative Regulation (REN) n ° 482/2012-improved by REN n ° 687/2015-by the National Electric Energy Agency (ANEEL), which launched the conditions for the access of micro and minigeneration distributed to the system of electricity compensation and which constitutes a milestone for generation distributed in the country, confirms this statement. The results of the work will show the feasibility of the mini and microgeneration distributed from the aid of the incentive policies, and will outline a current scenario in Brazil regarding the certification of the national and imported small wind turbines, evidencing the standards that were not adopted in the aforementioned Ordinance. and their impact on consumer safety and product quality assuran...

The use of plant fibers to replace artificial fibers such as carbon fiber or glass fiber is the subject of studies by many researchers today. Vegetable fibers are considered for their renewability, degradability, low toxicity and low cost. In this work, the mechanical properties of tensile and flexural strength and modulus of elasticity of hybrid composites of sisal fibers with glass fiber in an epoxy polymer matrix were evaluated. The fibers were treated in a 10% by weight sodium hydroxide solution and subjected to tensile tests in a universal testing machine according to the ASTM D3039 and D790 standards. The best performing composites were the sisal + fiberglass hybrids, at 86% for the tensile strength and 64% for the elastic modulus. In the bending tests the results showed a performance of 119% for the maximum stress and 138% in the greater breaking stress for the hybrid composites.

The study of vegetable fibers has been usual for the manufacture of many utensils in industry in general. Vegetable fibers are considered for their high renewability, high degradability, and low cost. In this work, the mechanical properties of the tensile and flexural strength and the modulus of elasticity of hybrid composites of jute fibers with fiberglass in an epoxy polymer matrix were evaluated. The fibers were treated in a 5% by weight NaOH solution and subjected to tensile tests in a universal testing machine according to the ASTM D3039 and D790 standards. The composites with the best performance were jute + fiberglass hybrids, with 113% for the tensile strength and 32% for the elastic modulus. In the bending tests, the results showed a performance of 111% for the maximum stress and 20% in the highest breaking stress for the hybrid composites.
