Özet
In this study, the thermal, mechanical, and morphological properties of high‐density polyethylene composites reinforced with wal1nut shell and nano‐CaCO3 were investigated. Composites with a fixed walnut shell content (20%) and varying nano‐CaCO3 concentrations (1%, 3%, and 5%) were prepared by extrusion and injection molding. The results showed that increasing filler content raised crystallization temperatures, while melting temperatures (Tm) slightly decreased, and crystallinity was lower compared to pure HDPE. The lowest Tm (128.2°C) and crystallinity (27.3%) were found in the PECCWS4 and PECCWS5 composites. Thermogravimetric analysis (TGA) revealed that the initial degradation temperature (T5) increased from 452°C to 457.8°C, and the temperature for 50% weight loss (T50) shifted from 481.8°C to 486.5°C. Residual weight at 600°C increased from 1.1% for PECCWS1 to 9.5% for …
