Abstract: Natural lignocellulosic fibers have an excellent potential as reinforcement in polymer industries. Further, ecological concern has triggered a significant interest in effective utilization of natural resources to produce eco-friendly products. The study emphasizes on the characterization of lignocellulosic composites using groundnut shell particles as reinforcement. The samples were prepared with different process parameters, namely, particle size, filler loading and alkali treatment of particles. The experiments were planned as per full factorial design. The relationships between process parameters and tensile strength and tensile modulus have been established by developing response surface methodology based models. The RSM based second order mathematical models are used to predict the tensile properties.  The adequacy of the proposed second order mathematical models has been tested through the analysis of variance (ANOVA).  The statistical measures and the validation tests show the excellent adequacy of the quadratic models. From parametric analysis, it is revealed that tensile strength and tensile modulus increase with increased filler loading up to 50-wt % and beyond 5% NaOH treatment of particles.
