“…The tensile strength decreased by as much as 14.3% from the third cycle to the seventh cycle. Aliyegbenoma and co‐workers [ 86 ] studied both the modeling and production of the injection molded polyvinyl chloride (PVC) reinforced with sawdust composite. The role and/or influence of temperature, material, and percentage (by volume) of the constituents on mechanical properties of the engineered composite was determined using response surface methodology (RSM).…”

“…From the third cycle to the fourth cycle, flexural strength of the composite decreased from 40 to 36 MPa and modulus of the composite decreased from 4763 to 4589 MPa. Aliyegbenoma and co‐workers [ 86 ] studied the effect of an interaction of test temperature, volume of material, and material type on mechanical properties of the PVC/sawdust composite using the approach of RSM. The maximum value of flexural strength was 61.41 MPa, and the elastic modulus was 3.42 GPa at a temperature of 224.65°C and polymer quantity of 61.46%.…”

Factors like environmental and societal awareness often lead to a significant change of action in the development of eco-friendly materials like the family of green composites. Green composites are becoming increasingly apparent as a sensible and potentially viable alternative to the synthetic composites. A healthy synergism of factors to include weight reduction, cost, performance improvement, biodegradable nature, nontoxic properties, and flexibility are often the key motives that provide the much needed impetus for the development of green composites for the purpose of selection and use in a spectrum of applications. The biodegradable or green composites became a viable substitute for the long-established materials and often a challenge to the family of synthetic polymer-based composites. The present study draws attention to the issues and challenges that come in the way of development and characterization of "green" composites primarily on the use of advanced manufacturing processes like injection molding. In this article, the chemical composition, structure, mechanical properties, and classification of the natural fibers are presented and briefly discussed. The mechanical properties, to include tensile response, flexural behavior, and impact strength, of the injection molded composites are presented and adequately discussed. The effect and role of surface treatments and coupling agents on mechanical properties of the family of polymer composites, to include the nonbiodegradable composites, partially green composites, and fully green composites, are examined and adequately discussed.green composite, injection molding, mechanical properties, natural fibers, processing | INTRODUCTION"Green" composite is a mixture of naturally occurring fiber and a biodegradable polymer (natural resin or synthesized resin). The "green" composites often tend to degrade easily at the end of their lifecycle. Invariably, "green" composites get converted to water (H 2 O) and carbon dioxide (CO 2 ) without appreciably influencing the environment. The synthetic polymer composites have a plethora of applications in the fields spanning automobile

Wood-based composites such as wood plastic composites (WPC) are emerging as a sustainable and excellent performance materials consisting of wood reinforced with polymer matrix with a variety of applications in construction industries. In this context, wood-based composite materials used in construction industries have witnessed a vigorous growth, leading to a great production activity. However, the main setbacks are their high flammability during fires. To address this issue, flame retardants are utilized to improve the performance of fire properties as well as the flame retardancy of WPC material. In this review, flame retardants employed during manufacturing process with their mechanical properties designed to achieve an enhanced flame retardancy were examined. The addition of flame retardants and manufacturing techniques applied were found to be an optimum condition to improve fire resistance and mechanical properties. The review focuses on the manufacturing techniques, applications, mechanical properties and flammability studies of wood fiber/flour polymer/plastics composites materials. Various flame retardant of WPCs and summary of future prospects were also highlighted.

“…Oilseed fibers showed superior mechanical properties due to their high aspect ratio and chemical characteristics. Aliyegebenoma et al [5] focused on the modeling and production of the injection molded Polyvinylchloride-Sawdust (PVC-sawdust) composite. The results for PVC-Sawdust composite showed that the tensile strength, proof stress, flexural strength and flexural modulus were maximized at barrel temperature of 224.65 ℃ and polymer level of 61.46% respectively the coefficient of determination (R2) obtained ranged from 0.9213 (92.13%) to 0.981 (98.10%).…”

The present study is focused on the possibility of use of PVC wastes and sawdust (dividing cut and edging of MDF panels) in WPC production. Variables included mixing ratio in three levels (45/55, 50/50 and 60/40), as well as press time of 8, 10, 12 minutes. Panels were compressed in a molde and physical and mechanical properties of panels including bending strength, tensile strength, bending and tensile modulus, impact strength and Thickness Swelling (TS) were measured. The results showed that the mechanical properties of panels were significantly higher when the PVC/Sawdust ratio was 50:50. Thicknesses swelling after 24 hours as well as long term holding decreased with the increase in PVC / sawdust ratio. In addition, the physical and mechanical properties of composite have been significantly affected by press time. It was concluded that the panel made of 50% PVC combined with 50% sawdust pressed for 8 minutes exhibited suitable properties for most applications.
