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 min. Nanofibers with the width of less than 100 nm were 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 properties of poly(lactic acid) composites reinforced with MFC were investigated. The interaction between MFC fibrils and PLA resin was observed. As a result, Youngs modulus and tensile strength of the composites increased to 3.1 GPa and 39 MPa respectively, compared to values of 2.4 GPa and 33 MPa for Youngs modulus and tensile strength of pure poly(lactic acid) resin. This indicates the stress can be transferred from the matrix to the reinforcement phase. The improvement of mechanical properties of the composites confirms that MFC prepared using a high speed blender can be used as reinforcement.
