Developing eco-friendly epoxy composites for rail vehicle seats, this study found polylactide and quercetin additives enhance material stability and aging resistance. These sustainable composites offer a promising alternative for enhanced durability and environmental benefits.
Area of Science:
- Materials Science
- Polymer Science
- Sustainable Engineering
Background:
- Traditional rail vehicle seat materials face challenges with environmental impact and durability.
- Developing sustainable and long-lasting composite materials is crucial for the transportation industry.
Purpose of the Study:
- To create environmentally friendly epoxy composites with enhanced service life for rail vehicle seat applications.
- To investigate the impact of polylactide (PLA) and quercetin additives on epoxy composite aging behavior.
Main Methods:
- Solar aging tests (800 h) on epoxy composites filled with PLA or PLA and quercetin.
- Thermogravimetric analysis (TGA) for thermal stability assessment.
- Optical microscopy, tensile testing, contact angle measurements, color change analysis, and Fourier-transform infrared (FTIR) spectroscopy.
Main Results:
- Additives maintained epoxy resin thermal stability and did not increase matrix defects.
- Polylactide (PLA) presence slightly enhanced stiffness and strength of epoxy composites.
- Quercetin oxidation provided protection to the epoxy matrix, confirmed by reduced carbonyl index (CI) via FTIR.
Conclusions:
- Epoxy composites with PLA and quercetin demonstrate high aging resistance and improved mechanical properties.
- These eco-friendly composites offer a viable, sustainable alternative for rail vehicle seat elements.
- The study highlights the potential of bio-based additives for enhancing polymer performance in demanding applications.
