Randomized trial demonstrates the effectiveness of epoxy-based hybrid composites for building insulation, suggesting a sustainable alternative.

This research aims to develop and characterize epoxy-based hybrid composites using sawdust and fly ash for structural insulation applications.
Hybrid composites were created using 95% epoxy and 5% reinforcing agents (sawdust and fly ash).
Mechanical tests measured strength improvements, and thermal analysis was performed using FTIR, TGA, and DSC techniques.
The study evaluated various fly ash particle sizes (0.5, 1, 1.5, 2 wt.%) and utilized a hand lay-up fabrication method.
Mechanical tests showed significant improvements in tensile strength, impact resistance, and compressive strength compared to neat epoxy.
Thermal conductivity decreased by 50% W/m·K as filler content increased, indicating enhanced insulation properties.
TGA indicated improved thermal resilience with delayed degradation onset and increased residual char due to fillers.
