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.

Study of hybrid intralaminate curaua/glass composites

Materials & Design, 2012
In this study, thermal, mechanical and dynamic mechanical analyses of hybrid intralaminate curaua/glass composites were carried out. Distinct curaua/glass fiber content ratio and overall fiber volume fraction (20, 30 and 40 vol.%) were studied. Thermal analysis showed higher thermal stability for the glass reinforcement.

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

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.
