Utilization of synthetic based mineral filler in wood plastics composite
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 77, Issue 2
Abstract
Purpose: Purpose of this paper is to utilize synthetic base mineral filler in wood plasticcomposites (WPCs) and to determine their physical, mechanical and thermal properties.Design/methodology/approach: Hybrid composites were produced by mixing woodflour (Turkish red pine (Pinus brutia Ten.), wax and maleic anhydride grafted polypropylene(MAPP) and polypropylene (PP) in a high intensity density mixer. The homogenous mixturewas extruded using a single screw extruder with five heating zones. Extrudates werepelletized and composite samples were injection molded. Density of the samples wasmeasured (ASTM D 792). Flexural strength (ASTM D 790), flexural modulus (ASTM D 790),tensile strength (ASTM D 638), tensile modulus, elongation at break and hardness (ASTMD22-40) were studied. Linear burning rate of the samples were also determined (ASTM D 635).Findings: According to test results synthetic based mineral filler and wood flour can usetogether for better composite properties and they provide adequate mechanical propertiesaccording to ASTM D 6662.Research limitations/implications: This article determined some of physical andmechanical properties of wood plastics hybrid composite which was manufactured withTurkish red pine flour and synthetic based mineral filler. As for the future researchers thesome wood plastics composites can be manufactured by different wood flour species andin different amounts of synthetic based mineral filler.Practical implications: Synthetic based mineral filler were added to the mixture eitherbefore extrusion or injection molding. Effect of mineral filler and wood flour amount was alsostudied.Originality/value: Addition of wood flour and synthetic based mineral filler intopolypropylene improved modulus values while reducing tensile strength, elongation andimpact values.
