Characterization of lignocellulosic curaua fibres

Carbohydrate Polymers, 2009
Curaua fibres have specific mechanical properties similar to inorganic fibres and are an important renewable raw material. Milled curaua fibres, submitted to different treatments, were characterized by mechanical and thermal properties, moisture content, water absorption, surface morphology, FTIR spectroscopy, density and X-ray diffraction.

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.

Analysis of curaua/glass hybrid interlayer laminates

Journal of Reinforced Plastics and Composites, 2014
This study compares the mechanical properties of curaua, glass and hybrid curaua/glass laminates evaluated experimentally with those obtained theoretically using commercial software for composites. Hybrids laminates were produced varying the fiber layer stacking sequence with the aim of optimizing the combination of vegetable and synthetic fibers ...

Dynamic mechanical properties of curaua composites

Journal of Applied Polymer Science, 2012
AbstractIn this study, we aimed to evaluate the characteristics of curaua composites using dynamic mechanical analysis. Curaua composites with distinct fiber volume fractions (11–38%) were studied, and their storage and loss moduli were found to increase with reinforcement content.

Performance of curaua fibers in pullout tests

Journal of Materials Science, 2007
Natural 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, 2010
Curaua 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 ...

Modeling the mechanical behavior of epoxy Curaua reinforced composites

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2022
In recent decades, it has become essential to find and develop materials from non-petroleum sources that are more compatible with nature. The present work describes the mechanical properties of a composite with epoxy matrix reinforced with natural Curaua fibers.

Characterization of Curaua Fibers by Infrared Spectroscopy

Materials Science Forum, 2014
Natural fibers obtained from plants are being investigated as possible engineering materials with application in polymer composite reinforcement. For instance, the lignocellulosic fibers extracted from the leaves of the curaua plant (Ananas erectifolius) display a reinforcement potential owing to their relatively high strength.

Curaua and eucalyptus nanofibers films by continuous casting: Mechanical and thermal properties

Carbohydrate Polymers, 2018
A wide variety of new green materials such as curaua leaf fibers (CLFs) has potential applications in nanotechnology. This study aims to investigate the thermomechanical properties and morphological structure of cellulose nanocrystals (CNCs) and cellulose nanofibrils (CNFs) films obtained by continuous casting. The CNCs were obtained by acid hydrolysis

The photodegradation and biodegradation of rEPS/curaua fiber composites

Polymer Composites, 2013
The development of composite materials comprised of postconsumer polymers and natural fibers is important for the possibility to obtain materials that are more compatible with the environment. Depending on the application of these materials and their final disposal, the relevant degradation processes must be considered in the studies of these materials.
