Enzymatically treated curaua fibers in poly(butylene succinate)-based biocomposites
Journal of Environmental Chemical Engineering, 2018Abstract The aim of this work is to elucidate the reinforcing potential of enzymatically treated curaua fibers in biodegradable poly(butylene succinate) (PBS)-based composites. The effect of two different enzymes, i.e. cellulase and pectinase, was evaluated.

Thermal Analysis of Curaua Fiber Reinforced Epoxy Matrix Composites
2016Thermoset polymers, like the epoxy, become harder with increasing temperature owing to molecular crosslink formation, which is a thermal benefit for composite matrix applications. Natural lignocellulosic fibers, however, have low thermal resistance and tend to degrade with increasing temperature.

Processing of a Green Fiber-Reinforced Composite of High-Performance Curaua Fiber in Polyester
JOM, 2018Lignocellulosic fibers extracted from the curaua plant are among the strongest natural fibers used as polymer composite reinforcements for engineering applications. However, to date, such composites have been limited in terms of their mechanical strength and impact energy. The objective of the present work is to investigate the possibility of improving

Characterization of composites based on recycled expanded polystyrene reinforced with curaua fibers
Journal of Applied Polymer Science, 2012AbstractThis study evaluated the mechanical, thermal, rheological, and morphological properties of virgin and recycled matrices and their composites with 20 wt % of curaua fiber. The recycling process of postconsumer polystyrene was carried out by grinding and extrusion.

Tensile Test of High Strength Thinner Curaua Fiber Reinforced Polyester Matrix Composite
Materials Science Forum, 2016In recent years natural fibers, especially those lignocellulosic extracted from plants, have gained attention owing to their engineering performance as polymer composite reinforcement. It was found that some of these lignocellulosic fibers, such as the curaua, ramie and sisal may reach tensile strength above 1000 MPa in association with very thin ...

Hybridization effect on the mechanical properties of curaua/glass fiber composites
Composites Part B: Engineering, 2013The aim of this paper was to evaluate the effect of hybridizing glass and curaua fibers on the mechanical properties of their composites. These composites were produced by hot compression molding, with distinct overall fiber volume fraction, being either pure curaua fiber, pure glass fiber or hybrid.
