Role of wood flour on physical and mechanical properties in polymer matrix composites-a critical review

Abstract

Green and sustainable material is the utmost prerequisite for the advancement of a healthy society and fulfilling the necessary for the improvement in material science. Naturally obtaining wood flour has the competence to be reinforced as a filler substance in the polymer composite. The present article deals with the usage of wood flour as a filler in the polymer composite. The article comprises properties, characteristics, occurrence, the structure of wood, and the techniques implemented in the manufacturing of wood flour polymer composites. In addition, critical parameters and causes that can bring changes in the properties like tensile, flexural, impact and hardness of polymers are also discussed with the addition of wood flour alone and with nanoparticles. The advantages of using wood flour as a filler in the thermoset and thermoplastic polymers discussed, and its hybridization with various natural fibers was also discussed in the present study.
