Adding value to the Brazilian sisal: acid hydrolysis of its pulp seeking production of sugars and materials
(SPRINGERDORDRECHT, 2012)
The present work is inserted into the broad context of the upgrading of lignocellulosic fibers. Sisal was chosen in the present study because more than 50% of the world's sisal is cultivated in Brazil, it has a short life ...
Biobased composites from glyoxal-phenolic resins and sisal fibers
(ELSEVIER SCI LTD, 2010)
Lignocellulosic materials can significantly contribute to the development of biobased composites. In this work, glyoxal-phenolic resins for composites were prepared using glyoxal, which is a dialdehyde obtained from several ...
Phenolic matrices and sisal fibers modified with hydroxy terminated polybutadiene rubber: Impact strength, water absorption, and morphological aspects of thermosets and composites
(ELSEVIER SCIENCE BV, 2010)
The aim of the present work was to investigate the toughening of phenolic thermoset and its composites reinforced with sisal fibers, using hydroxyl-terminated polybutadiene rubber (HTPB) as both impact modifier and coupling ...
Thermoset matrix reinforced with sisal fibers: Effect of the cure cycle on the properties of the biobased composite
(ELSEVIER SCI LTD, 2009)
Thermoset phenolic composites reinforced with sisal fibers were prepared to optimize the cure step. In the present study, processing parameters such as pressure, temperature, and time interval were varied to control the ...
The influence of UV-C irradiation on the properties of thermoplastic starch and polycaprolactone biocomposite with sisal bleached fibers
(Elsevier B.V., 2012-10-01)
The effect of UV-C irradiation of the TPS and PCL biocomposites with sisal bleached fibers was investigated. The biocomposite was UV-C irradiated at room temperature under air atmosphere. The structural and morphological ...
Phenol-furfural resins to elaborate composites, reinforced with sisal fibers - Molecular analysis of resin and properties of composites
(JOHN WILEY & SONS INC, 2008)
Resol type resins were prepared in alkaline conditions (potassium hydroxide or potassium carbonate) using furfural obtained by acid hydrolysis of abundant renewable resources from agricultural and forestry waste residues. ...
Caracterização mecânica e térmica de compósitos de poli (cloreto de vinila) reforçados com fibras de sisal
(Associação Brasileira de Polímeros, 2004-12-01)
Compósitos de PVC, plastificados com diferentes sistemas de plastificação e reforçados com fibras de sisal, foram processados em moinho de dois rolos. A influência do tipo e teor do plastificante, do comprimento e do teor ...
Resíduos de sisal como reforço em compósitos de polipropileno virgem e reciclado
(Associação Brasileira de Polímeros, 2011)
Foram estudadas as propriedades térmicas e mecânicas de compósitos de polipropileno, virgem e reciclado, reforçados com 30% em massa de fibras residuais de sisal, assim como o perfil de processamento e a morfologia da ...
