| Abstract | Bamboo fibers, as a raw cellulose source, were used to prepare microfibrillated cellulose (MFC)using a high speed blender at 20,000 rpm for 60 minutes. Nanofibers with the width of less than 100 nmwere disintegrated from the fibers. MFC networks were then prepared, and embedded in poly(lactic acid)resin using a compression molding at temperature of 180?C and a pressure of 10 MPa. Mechanical propertiesof poly(lactic acid) composites reinforced with MFC were investigated. The interaction between MFC fibrilsand PLA resin was observed. As a result, Young's modulus and tensile strength of the composites increasedto 3.1 GPa and 39 MPa respectively, compared to values of 2.4 GPa and 33 MPa for Young's modulus andtensile strength of pure poly(lactic acid) resin. This indicates the stress can be transferred from the matrix tothe reinforcement phase. The improvement of mechanical properties of the composites confirms that MFCprepared using a high speed blender can be used as reinforcement. |
