Abstract: | The dynamic mechanical and thermal analysis of oil palm empty fruit bunch (EFB)/woven jute fibre (Jw) reinforced epoxy hybrid composites were carried out. The storage modulus (E′) was found to decrease with temperature in all cases, and hybrid composites had showed better values of E′ at glass transition temperature (Tg) compared to EFB and epoxy. Loss modulus showed shifts in the Tg of the polymer matrix with the addition of fibre as reinforcing phase, which indicate that fibre plays an important role in case of Tg. The Tan δ peak height was minimum for jute composites and maximum for epoxy matrix. Complex modulus variations and phase behaviour of the hybrid composites was studied by Cole-Cole analysis. Thermal analysis result indicates an increase in thermal stability of EFB composite with the incorporation of woven jute fibres. Hybridization of EFB composite with Jw fibres enhanced the dynamic mechanical and thermal properties. |
