Investigation of the Physicochemical, Thermal, and Mechanical Properties of a Single Fiber Extracted From Imperata Cylindrica Plant

open access: yesAdvances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
This study investigated the physical, chemical, thermal, and mechanical properties of Imperata cylindrica (IC) fibers extracted using 2 wt%, 4 wt%, and 6 wt% NaOH. Since 6 wt% NaOH yielded complete removal, fibers obtained from this concentration were furthermore treated with 1% concentration of silane before characterization.

Recent Progress on the Physical, Thermal, and Mechanical Properties of Expanded Polystyrene Waste–Based Composites

open access: yesInternational Journal of Polymer Science, Volume 2025, Issue 1, 2025.
Expanded polystyrene (EPS) waste also known as Styrofoam is a common material found in packaging and insulation applications and presents significant environmental challenges due to its nonbiodegradable nature. To address this issue, researchers have explored EPS waste as a potential polymer matrix for developing composite materials.

Curaua/polypropylene composites: Phase compatibilization and alternative micromechanics modeling

open access: yesIndustrial Crops and Products
Curaua strands, a natural fiber scarcely explored for reinforcement applications, were investigated as the dispersed phase in polypropylene composites. Although maleic anhydride-grafted polypropylene (MAPP) is widely used as a compatibilizer in natural ...

Degradation mechanisms of curaua, hemp, and sisal fibers exposed to elevated temperatures [PDF]

open access: yesBioResources, 2019
The influence of elevated temperatures on mechanical behavior was studied for curaua, hemp, and sisal natural fibers. Tensile tests were performed on fibers heated at 100 °C, 150 °C, and 200 °C for 24 h, and reference samples were maintained without thermal treatment for comparisons.

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

open access: yesJournal 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 ...

Valorization of coffee silverskin by cascade extraction of valuable biomolecules: preparation of eco‐friendly composites as the ultimate step

open access: yesBiofuels, Bioproducts and Biorefining, Volume 18, Issue 2, Page 524-542, March/April 2024.
Abstract This study presents a multidisciplinary approach for dealing with the environmental problems related to agro‐industrial coffee residues. The exploitation of these residues allows biomolecules to be obtained from renewable sources and enables the preparation of CO2‐neutral biocomposites, with the advantages of reducing fossil depletion ...

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

open access: yesInternational 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.
