Saccharification of Brazilian sisal pulp: evaluating the impact of mercerization on non-hydrolyzed pulp and hydrolysis products
Cultivation of sisal, a plant with a short growth cycle, is highly productive in Brazil. This work is part of extensive research in which sisal is valued. In these studies, sisal fibers are used in the preparation of ...
Adding value to the Brazilian sisal: acid hydrolysis of its pulp seeking production of sugars and materials
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 ...

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 ...
