Mechanical and thermal behavior of natural fiber-polymer composites without compatibilizers
Abstract
The present study aims at understanding the mechanical and thermal properties of natural fibers in a polymer matrix without strong adhesionbetween the two constitutes.Forthispurpose,fourtypesofpulps,whicharerefinedand unrefinedpineandbirchkraftpulps,wereusedtogetherwithpolypropylene withoutanycompatibilizer.Oneconstituentpulpbasedandcomposite pulp fiber-polypropylenehandsheetswerepreparedbystandardlaboratorysheet preparationmethodfollowedby hotpressingprocess.Inadditiontothese handsheets, pure polypropylene sheets were also formed as the reference. The produced handsheets were testedtodetermine their tensile properties following theISO1924-2 standard forpaperandboard.Duringthesetests,infrared thermalimagingwasalsocarriedout withFLIRA655SCthermalcamerawith framerate of200Hzandthermal resolution of50mK soas toinvestigate the thermal behavior. As a result of the experiments, it was deducedthat the chosen methodsproducedcompositeswithunsatisfactoryproperties.Inaddition, microstructuresoftheinvestigatedhandsheetswereanalyzedwithscanning electronmicroscopy (SEM)indicating theheterogeneous mixing of constituents andexistenceofmaterialdefects,whichwasmainlyduetotheinherent incompatibilityofhydrophilicnatural fibersandhydrophobicthermoplastics. The study aims at pavinga way for improved naturalfiber-polymer composite manufacturingmethods,arequirementforbetterunderstandingthenatural fiberand polymer matrix bonding practices.
