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.

The use of curaua fibers as reinforcements in composites

2015
Nowadays, there is growing worldwide interest in the use of natural renewable materials to replace synthetic polymers or improve the properties of current materials. Natural fibers seem to offer a great opportunity in this respect, and among them curaua (. Ananas erectifolius L. B. Smith) fiber has unique properties, such as high strength, low density,

Statistical Experimental Design for Obtaining Nanocellulose from Curaua Fiber

Macromolecular Symposia, 2012
AbstractSummary: This study focuses on the methodology to obtain nanocellulose from vegetal fibers. An experimental planning was carried out for the treatment of curaua fibers and parameters were estimated, having the concentration of H2SO4, hydrolysis time, reaction temperature and time of applied sonication as independent variables for further ...

Thermal Analysis of Curaua Fiber Reinforced Epoxy Matrix Composites

2016
Thermoset 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.

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.

Characterization of composites based on recycled expanded polystyrene reinforced with curaua fibers

Journal of Applied Polymer Science, 2012
AbstractThis 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.
