Morfologia e propriedades mecânicas da fibra de sisal unidirecional e em sobreposição de compósito com resina epóxi
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2013-01-14)
The composites manufactured with long fibres aligned in a single direction, and overlay has been shown to have better performance than the short fibers randomly distributed. In particular, the lignocellulosic fibers extracted ...
Oxygen plasma treatment of sisal fibers and polypropylene: Effects on mechanical properties of composites
(Soc Plastics Eng Inc, 2002-04-01)
Polypropylene powder and sisal fibers were oxygen plasma treated, and the mechanical properties of their composites were tested. Two main effects were investigated: the incorporation of oxygen polar groups in the polypropylene ...
Tannin-phenolic resins: Synthesis, characterization, and application as matrix in biobased composites reinforced with sisal fibers
(ELSEVIER SCI LTDOXFORD, 2013-08-02)
A tannin-phenolic resin (40 wt% of tannin, characterized by H-1 nuclear magnetic resonance (NMR) and C-13 NMR, Fourier transform infrared, thermogravimetry, differential scanning calorimetry) was used to prepare composites ...
Adsorção de cobre e cromo utilizando fibra de sisal visando o tratamento da água produzida pela indústria petrolífera
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2010-07-19)
Currently, the oil industry is the biggest cause of environmental pollution. The objective was
to reduce the concentration of copper and chromium in the water produced by the oil industry.
It was used as adsorbent natural ...
Estudo da biodegradação das fibras de coco e de sisal visando às aplicações na indústria automotiva
(Universidade Estadual Paulista (UNESP), 2005-04-13)
Neste trabalho são discutidos os resultados referentes aos ensaios de biodegradabilidade de fibras naturais utilizadas pela indústria auotomobilística: fibra de coco, de coco com látex e e sisal. Estes ensaios foram ...
Sistema supervisório para o método de elevação plunger lift
(ABPG, 2009)
The several existing methods for oil artificial lifting and the variety of automation equipment for these methods many times lead the supervisory systems to be dedicated to a unique method and/or to a
unique manufacturer. ...
Celulose bacteriana obtida por diferentes fontes agroindustriais.
(In: CONGRESSO BRASILEIRO DE POLÍMEROS, 13., 2015, Natal. [São Carlos: Associação Brasileira de Polímeros], 2015. SP1.02.21. AJVB., 2015)
Hybrid Reinforcement of Sisal and Polypropylene Fibers in Cement-Based Composites
(ASCE-AMER SOC CIVIL ENGINEERS, 2011)
Several studies using vegetable fibers as the exclusive reinforcement in fiber-cement composites have shown acceptable mechanical performance at the first ages. However, after the exposure to accelerated aging tests, these ...
