Abstract

In this study, Ramie Cellulose Nanofiber (CNF) and CaCO3 were used as a reinforcement of composite with Unsaturated Polyester Resin (UPR) matrix. Ramie CNF was prepared by HEM (high energy milling) and dried in drying oven at 50°C for 24 h. It mixed with UPR matrix by hand layup casting method. Methylethylketone peroxide (MEKPO) and CaCO3 were added in the mixture solution with the amount of 1wt% and 2wt% respectively by stirring manually. The tensile test was carried out to know the mechanical properties of biocomposite. The fracture surface was observed by using Scanning Electron Microscopy (SEM). Fourier Transform Infrared (FT-IR) and Thermogravimetric Analysis (TGA) were also performed to know the functional group and thermal stability, respectively. The result shows that the addition of CNF and CaCO3 able to increase thermal stability and mechanical properties of biocomposite.
