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 Raw and Treated Curaua Fibers to be Applied as Reinforcement in Composites
Materials Science Forum, 2012Lignocellulosic fibers present several advantages over synthetic fibers, such as low cost and biodegradability. In this work the tensile mechanical behavior of as-received and surface treated curaua fibers was analyzed. Mercerization and three different enzyme surface treatments were used.

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.

Influence of Alkaline Hornification Treatment Cycles on the Mechanical Behavior in Curaua Fibers
Macromolecular Symposia, 2018A well‐known treatment applied in vegetable fibers in both paper and cellulose industry is named hornification. This treatment consists in soaking and drying cycles aiming promoting a reducing in the water absorption capability of the fibers, which causes a stiffening in the cellulosic structure increasing the dimensional stability and consequently ...
