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

Advances 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.

Modificação das propriedades das fibras de curauá por acetilação Modification of the properties of curauá fibers by acetylation

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
Nos compósitos cimentíceos as fibras vegetais podem sofrer vários graus de degradação quando expostas ao ambiente alcalino. O meio alcalino degrada os componentes macromoleculares das fibras, principalmente pela solubilização da lignina e a desfibrilação

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

International 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.

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

BioResources, 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.
