Fabrication of Chemically Modified Jute Fabric and Nonwoven Wet-Laid Glass Fiber Reinforced Polycaprolactone Composite

Ajoy Roy, Fahad Halim

In recent decades, scientific research giving more attention to the development of bio-based polymer composites due to the extensive usage of petroleum-based fillers as well as polymer matrices for the generation of polymer composites. In this study, high-moisture regain nature of cellulosic jute fiber significant drawback for jute-based application to reduce the issue and develop better interfacial adhesion hydrophobic nonwoven PP wet-laid glass-fiber matt used with polycaprolactone as a matrix. Nonwoven jute fabric categorized in untreated, silane, alkali and silane alkali combined modified afterward compounded with the solution of Polycaprolactone (PCL). Fabrication of composite performed following sandwich method according to different hot-pressing time, pressure and temperature for detecting a prominent fabrication parameter. Hence, mechanical properties like tensile and impact strength investigation performed to find the consequence after chemical treatment from the non-woven jute fabric resulting in 48.38%, 32.04% improved in tensile strength and modulus with 39.58% reduced impact strength in alkali silane combined treated composite over untreated optimized composites the Scanning Electron Microscope (SEM) used for displaying interfacial adhesion between fiber and polymer matrix. Besides, further investigation demonstrating due to combined treatment of alkali and silane optimized composites significantly enhanced the Thermogravimetric (TGA) stability in contrast to other composites.
