Wood plastic composites (WPC) are becoming popular in recent years, in majorly automobile and building sectors due to their attractive properties and sustainability compared to traditional materials. This work focuses at mechanical property evaluation of WPCs made of teak wood flour (wastes obtained from wood cutting mills), Poly Vinyl Chloride (PVC) and Calcium Carbonate as major ingredients. Fabrication of WPC is done using the extrusion process. Tensile, compressive, bending and impact tests were carried out as per ASTM standard testing method D 4761-19 to evaluate mechanical properties of the WPC. It was found that above said WPC has tensile strength of 7.69N/mm2, compression strength of 11.42N/mm2, flexural strength of 15.264N/mm2 and impact strength (Izod) of 0.265 N-M/mm2. From these mechanical properties of proposed PWC, it can be concluded that it can replace natural wood, when mechanical performance requirements are within above mentioned allowable values and where seasonal affect, humidity, moisture absorption etc. are the major problems. Additionally since wood waste is used in proposed PWC, material is considered more sustainable and eco-friendly. Keywords: WPC, PVC, Teak saw dust, Extrusion, ASTM, sustainable

Purpose The purpose of this study is to carry out an investigation of the role of the wood particle size on the mechanical properties of poly lactic acid (PLA)-reinforced neem fiber biocomposite. Design/methodology/approach Composite test specimens were processed by reinforcing neem wood flour (NWF) in two different particle sizes, micro-sized NWF (MNWF) and nano-sized NWF (NNWF) separately into PLA. Composites were extruded at four different fiber loadings (10, 15, 20 and 25 Wt.%) into PLA matrix. The MNWF and NNWF had particle sizes varying from 5 to 15 µm and 10 to 15 nm, respectively. Findings Tensile strength, flexural strength and impact strength of PLA increased with fiber reinforcement for both the MNWF and NNWF cases. The NNWF-reinforced PLA composite at 20 Wt.% fiber loading proved to be the best composite that had outstanding mechanical properties in this research. Practical implications The developed composite can be used as a substitute for conventional plywood for furniture, building infrastructure and interior components for the automobile, aircraft and railway sectors. Originality/value A new biocomposite had been fabricated by using PLA and NWF and had been tested for its mechanical characteristics.
