Abstract
In this work, the influence of microfibrillated cellulose (MFC) on the basic mechanical properties
of PLA/kenaf fiber biocomposites has been studied. The addition of 5–15 % microfibrillated cellulose to a
biocomposite premix has resulted in an increased glass transition temperature of the final product, produced by
compression molding of previously melt-mixed composite components. The presence of MFC has influenced
the interface-sensitive properties of the PLA/kenaf composite: at an optimal loading of 10 %, the interfacial
energy release rate was increased by about 20 %. Moreover, flexural strength and modulus of the composites
were also improved (from 34.8 MPa to 57.1 MPa and from 4.9 GPa to 5.8 GPa, respectively).
Keywords: biocomposites; poly(lactic acid); kenaf fibers; microfibrillated cellulose
