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.
