木粉填充PVC树脂复合材料力学性能的研究 Title:InvestigatingtheMechanicalPropertiesofPVCResinCompositeMaterialReinforcedwithWoodFlour Abstract: PVCresin-basedcompositesarewidelyusedinvariousindustriesduetotheirdesirablemechanicalpropertiesandlowcost.Inrecentyears,therehasbeengrowinginterestinincorporatingnaturalfillers,suchaswoodflour,toenhancethemechanicalpropertiesandsustainabilityofthesecomposites.ThisstudyaimstoinvestigatetheeffectofwoodflourasafilleronthemechanicalpropertiesofPVCresincompositematerials. Introduction: PVCresinisawidelyusedthermoplasticmaterialduetoitsflexibility,durability,andlowcost.However,theinherentbrittlenessandlimitedmechanicalstrengthofPVCresinrestrictitsapplicationsincertainindustries.ToimprovethemechanicalpropertiesofPVCresin,variousfillershavebeenintroducedintothecompositematerial.Amongthesefillers,woodflourholdspromiseduetoitsavailability,sustainability,anddesirablemechanicalproperties.Therefore,thisstudyfocusesoninvestigatingtheincorporationofwoodflourasafillerinPVCresincomposites.
