Composites of natural rubber with curaua fibers [PDF]
PolímerosAbstract This paper analyzed the thermal and mechanical properties of natural rubber/curaua fiber composite with different weight contents (2.5% to 15%). Alkali treatment was used to modify the surface of curaua fiber and improve interfacial bonding. Results showed that alkali treatment did not affect the dispersion pattern of composites.

Cellulose Nanowhiskers Extracted from Tempo-Oxidized Curaua Fibers
Journal of Natural Fibers, 2019 The objective of this study was to obtain nanowhiskers from bleached and milled curaua fibers. Nanowhiskers were obtained via a TEMPO system. TEM micrographies proved the fibers were obtained. FTIR analysis showed characteristic peaks of the oxidation products for the samples submitted to the treatment, suggesting that the it was effective for ...

Hemicellulose Removal in Curaua (Ananas erectifolius) Fibers for Polyester Composites
Nova Scientia, 2018 Introduction: Alkaline treatments extract hemicellulose from the fibers, which can be reused in the manufacture of other materials, and the cellulosic portion can be applied as reinforcement in a composite. This way, all components of the fibers are utilized.Method: In this work, curaua fibers (Ananas erectifolius) were treated with potassium hydroxide

Mechanical Properties Analysis of Polypropylene Biocomposites Reinforced with Curaua Fiber [PDF]
Materials Research, 2015 Over the last few years, great interest has been shown by researchers in presenting alternative proposals for the design and fabrication of materials with good mechanical properties and low cost for a variety of applications. With this in mind, a study was carried out on the addition of curaua fibers in a polypropylene (PP) matrix.

Technical Assessment of Leaf Fibers from Curaua: An Amazonian Bioresource
Journal of Natural Fibers, 2021 The main goal of this study is to assess the mechanical, physical and morphological properties of bundle fibers extracted from curaua leaves and pullout testing in cementitious matrix. The mechanical properties of the fibers were analyzed in mechanical testing of four fiber lengths (10, 20, 30 and 40 mm) to observe the influence of the length of the ...
