Characterization of Curaua Fiber
Molecular Crystals and Liquid Crystals, 2000 Abstract This paper describes the chemical, thermal and thermomechanical characterization of curaua fiber. The research of the thermal and thermomechanical properties of natural fibers is of major interest, considering their increasing utilization in several applications, and the large temperature range to which the fibers are submitted.

Recycled Polypropylene Reinforced With Curaua Fibers by Extrusion
Journal of Applied Polymer Science, 2009 AbstractCuraua fibers were studied as reinforcing agents for postconsumer polypropylene. The composites were processed by extrusion. The composite properties were investigated by mechanical tests, thermal methods, melt flow index, surface morphology, and water uptake.

Ionized-Air-Treated Curaua Fibers as Reinforcement for Phenolic Matrices
Macromolecular Materials and Engineering, 2008 AbstractCuraua fibers were treated with ionized air to improve the fiber/phenolic matrix adhesion. The treatment with ionized air did not change the thermal stability of the fibers. The impact strength increased with increase in the fiber treatment time.

The Use of Curaua Fibers as Reinforcements in Composites
, 2015 Nowadays, there is growing worldwide interest in the use of natural renewable materials to replace synthetic polymers or improve the properties of current materials. Natural fibers seem to offer a great opportunity in this respect, and among them curaua (. Ananas erectifolius L. B. Smith) fiber has unique properties, such as high strength, low density,

Mechanical Behavior of Unidirectional Curaua Fiber and Glass Fiber Composites
Macromolecular Symposia, 2012AbstractSummary: This work intends to promote the use of natural fibers by comparing the behavior of isophthalic polyester matrix composites reinforced with unidirectional curaua fibers with that of unidirectional glass fiber composites. The composites were produced varying the reinforcement angle (0°, 15°, 30°, 45°, 60°, 75° and 90°) with the aim of ...

Performance of curaua fibers in pullout tests
Journal of Materials Science, 2007Natural lignocellulosic fibers are successfully replacing synthetic fibers as the reinforcement phase of composite materials in many engineering applications, including automobile parts. In addition to well-known conventional lignocellulosic fibers, others with promising properties, like that obtained from the leaves of the curaua plant (Ananas ...

Cellulose nanofibers from curaua fibers
Cellulose, 2010Curaua nanofibers extracted under different conditions were investigated. The raw fibers were mercerized with NaOH solutions; they were then submitted to acid hydrolysis using three different types of acids (H2SO4, a mixture of H2SO4/HCl and HCl). The fibers were analyzed by cellulose, lignin and hemicellulose contents; viscometry, X-ray diffraction ...
