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.

Materials Prepared From Biopolyethylene and Curaua Fibers: Composites From Biomass

Polymer Testing, 2012
AbstractComposites of high-density biopolyethylene (HDBPE) obtained from ethylene derived from sugarcane ethanol and curaua fibers were formed by first mixing in an internal mixer followed by thermopressing. Additionally, hydroxyl-terminated polybutadiene (LHPB), which is usually used as an impact modifier, was mainly used in this study as a ...

Curaua Fibers/Epoxy Laminates With Improved Mechanical Properties: Effects of Fiber Treatment Conditions

Macromolecular Symposia, 2014
SummaryThe use of lignocellulosic fibers as reinforcement in polymer composites has increased worldwide recently. Vegetal fibers have low cost and they are commonly available in Brazil. The curaua fibers in particular are of great importance for the development of the Amazon region.

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.

Processing and Properties of Continuous and Aligned Curaua Fibers Incorporated Polyester Composites

Journal of Materials Research and Technology, 2013
AbstractThis paper presents systematic studies carried out on the processing and characterization of continuous and aligned curaua fibers-polyester composites. Laminates of these composites with (0 to 40 vol. %) curaua fibers were press-molded at room temperature, cured for 24hours and tested for strength properties.

Improvement of Mechanical Properties of Curaua Fiber Green Composites

Key Engineering Materials, 2007
Environment-friendly green composites were developed by combining a biodegradable resin with curaua fibers. The composites were fabricated by three different methods, i.e. direct, pre-forming and prepreg sheets methods. Mechanical properties of composites fabricated by all three methods were evaluated through tensile test.

Natural Curaua Fiber-Reinforced Composites in Multilayered Ballistic Armor

Metallurgical and Materials Transactions A, 2015
The performance of a novel multilayered armor in which the commonly used plies of aramid fabric layer were replaced by an equal thickness layer of distinct curaua fiber-reinforced composites with epoxy or polyester matrices was assessed. The investigated armor, in addition to its polymeric layer (aramid fabric or curaua composite), was also composed of

Processing of a Green Fiber-Reinforced Composite of High-Performance Curaua Fiber in Polyester

JOM, 2018
Lignocellulosic 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, 2012
Lignocellulosic 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.

Composite Materials in Epoxy Resin Matrix Using Curaua Fibers

2020
Vegetable fibers have good mechanical properties, low density, no toxicity, are renewable and have low cost among other properties. The use of lignocellulosic fibers as reinforcement in polymeric composite materials in substitution of synthetic fibers is in the direction of sustainability.
