Effects of Polymer Loading on Tropical Wood Polymer Composite (WPC)
Batai (paraserianthes moluccana) tropical wood species was impregnated with three levels of polyvinyl alcohol (PVA) solutions (25%, 50% and 75%) for composite manufacturing. Manufactured wood polymer composites (WPCs) were characterized using Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), free-free vibration testing, and the dimensional stability analysis. The dynamic Young’s modulus (Ed) was calculated using the free-free flexural vibration method. Impregnation of PVA solutions into wood samples was confirmed through FTIR and SEM. WPC from 75% PVA solution showed lower water absorption and improved dimensional stability. The fabricated WPC yielded a higher Young’s modulus compared with the raw one.
