Cellulose-based natural fibers such as jute and kenaf have increasingly used because of many advantages like low cost, light weight and biodegradability and high specific mechanical properties. However, natural fibers need an appropriate surface modification due to lack of interfacial adhesion between raw natural fibers and polymers. Electron beam (E-beam) treatment is particularly interesting as it offers the possibility to modify the natural fiber surfaces. Also E-beam process is a dry, clean and cold method with fast, uniform irradiation and eco-friendliness. In the present study, jute fibers were treated at various electron beam dosages between 2 kGy and 100 kGy. The objective of this work is to investigate the effect of E-beam treatment on various thermal properties of randomly oriented jute fiber/poly(lactic acid) green composites in terms of dynamic mechanical thermal properties, thermal expansion, thermal stability, and heat deflection temperature and the water absorption. |
