Washed banana fibers were mixed with high density polyethylene (HDPE) and placed in an injector chamber to produce specimens for tensile tests. Samples of washed bananafibers/HDPE composites were characterized by tensile tests and thermal analysis. The chemical composition of unwashed and washed banana fibers was analyzed by thermogravimetric analysis, scanning electron microscopy, and X-ray diffraction. The treatment with water was effective at removing extractives and increasing the surface roughness, thereby increasing the thermal stability of the fibers. However, results showed that the addition of washed banana fibers decreased the thermal stability of composites, while increasing the melting and crystallization temperatures of composites. The addition of 5 wt% fibers also provided an improvement in mechanical properties of composites in comparison with pure HDPE.2351-2365engBanana peel fibersCompositesHigh density polyethyleneThermal analysesBanana peelsChemical compositionsHigh density polyethylene(HDPE)Lignocellulosic fibersMelting and crystallization temperaturesPolymeric matricesProperties of compositesUnwashed fibersComposite materialsFibersFruitsHigh density polyethylenesMechanical propertiesScanning electron microscopySurface roughnessTensile testingThermoanalysisThermodynamic stabilityThermogravimetric analysisWater treatmentX ray diffractionReinforced plasticsGravimetryMechanical PropertiesPolyethyleneScanning Electron MicroscopyTensile TestsThermal AnalysisWater TreatmentX Ray DiffractionArtigoWOS:000320185500025Acesso aberto2-s2.0-848779797852-s2.0-84877979785.pdf35115347958057766119671014416126
