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 ...

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.

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 ...

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.

Early-age shrinkage of cement pastes with polypropylene and curaua fibres

Advances in Cement Research, 2021
The aim of this research was to investigate the effect of the addition of discrete polypropylene fibres (PPF) and curaua fibres (CF) on the early-age autogenous and drying shrinkage of cement pastes. The fibres used were 12 mm long and the volume fraction varied from 0.3 kg/m3 (0.03%) to 2.7 kg/m3 (0.30%).

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
