INVESTIGATION ON PHYSICO-CHEMICAL, MECHANICAL AND THERMAL PROPERTIES OF EXTRACTED NOVEL PINUS ROXBURGHII FIBER

The adverse environmental effects of synthetic fibers have forced researchers to use natural in composite preparation. Pinus Roxburghii Needles (PRNs) are widely available the hilly region Uttarakhand state, India. Utilizing fiber extracted from PRNs as reinforcement bio-composite preparation can reduce and emphasize resources. In this study, we extract Fibers (PRFs) using water retting method. Their physical, chemical, thermal, morphological aspects were investigated reported. average diameter density PRFs obtained 145 ± 17.36 µm 1020 20.27 kg/m3, respectively. chemical analysis revealed that contain 58.30% cellulose content. Thermal stability maximum degradation temperature assessed thermogravimetric (TGA) found be 225°C 355.84°C, Field Emission Scanning Electron Microscope (FESEM) Atomic Force (AFM) used study surface morphology roughness PRFs, Further, FTIR confirmed presence different functional groups cellulose, hemicellulose, lignin. crystallinity index (43.52%) crystal size (4.03 nm) determined X-ray diffraction (XRD) analysis.
