The current investigation has been performed on the microwave irradiated plant-derived cellulosic Sunn Hemp fiber and its composites. The fibers are pretreated by microwave irradiation at a power of 160 watts with different exposure times (2, 4, 6 and 8 minutes). The significant change in fiber and hence composite due to microwave treatment are characterized both in structural and mechanical property. A reasonable increment in cellulose crystallinity with crystallite size, rough surface with fine fibrillation in fiber may lead to improve the mechanical strength in the composite for 4min treatment. The macromolecular structure of the fiber is unaltered by the microwave radiation as indicated by Fourier Transmission Infrared Spectra.
