Abaca fiber as an efficient reinforcement for high mechanical performance in metakaolin‐based geopolymers

International Journal of Applied Ceramic Technology, Volume 21, Issue 2, Page 1154-1169, March/April 2024.
Abstract This study introduces an innovative method for efficiently integrating abaca fibers into a potassium‐based geopolymer (KGP) material. Geopolymers often suffer from brittleness, and composite designs have been explored as a solution to enhance their strength and ductility.

Chemical Characterization of Lignin and Lipophilic Fractions from Leaf Fibers of Curaua (Ananas erectifolius) [PDF]

Journal of Agricultural and Food Chemistry, 2007
The chemical composition of leaf fibers of curaua (Ananas erectifolius), an herbaceous plant native of Amazonia, was studied. Special attention was paid to the content and composition of lignin and lipophilic compounds. The analysis of lignin in the curaua fibers was performed in situ by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and ...

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 ...
