Abstract

This research project is an extensive experimental study on bio-extracted husk fiber polymer composites with a focus on silane surface treatment. Bio-extracted rice husk fibers underwent an alkali-enzymatic hybrid extraction process followed by a 3-aminopropyltriethoxysilane (APTES) treatment for improved interfacial adhesion and matrix compatibility. Resin composites with treated and untreated fibers were fabricated with a weight ratio of 10%, 20%, and 30% via hand lay-up methods. A battery of mechanical testing (tensile, flexural, impact), thermal characterization (TGA, DSC), morphological testing (SEM, FTIR) and moisture absorption testing were subsequently conducted. Silane treated fibers provided improved interfacial adhesion compared to controls with a 48% increase in tensile strength and 41% increase in flexural strength. TGA revealed a 17% increase in thermal stability at degradation temperature and SEM micrographs demonstrate improved matrix encapsulation of fibers. Life Cycle Assessment was conducted for an environmental analysis against synthetic fiber composites and ultimately, silane treated rice husk composites are a cost-effective alternative to synthetic composites with sustainable benefits for the automotive, construction and infrastructure sectors.

Keywords: Bio-extracted fibers; Silane treatment; Husk fiber; Epoxy composites; Mechanical properties; Thermal stability; Life cycle assessment
