Artigo IPEN-doc 23881 Comparison between HDPE/clay and HDPE/piassava fiber/clay treated by electron beam radiation2013 - ORTIZ, ANGEL; ESCANHOELA, CORDELIA M.F.; GOMES, MICHELLE; OLIVEIRA, RENE R.; DIAZ, FRANCISCO R.V.; MOURA, ESPERIDIANA A.B.This work evaluates changes in morphological, mechanical and thermo-mechanical properties of electron-beam irradiated HDPE/nanoclay and HDPE/Piassava fiber/nanoclay. Material samples irradiated with 100 and 200 kGy using a 1.5 MeV electron beam accelerator (room temperature, presence of air) were submitted to tensile, flexural, and HDT tests. MFI, SEM and XRD analyses were carried out. Correlation between properties was discussed. Results showed that incorporation of piassava (Attalea funifera Mart) fiber and nanoclay, followed by irradiation represented significant gain in thermo-mechanical properties. Changes in surface morphology and reduction in MFI were observed. In conclusion, it may be claimed that the incorporation of piassava fiber in small size particles and nanoclay in the HDPE followed by electron-beam irradiation effectively improved the polymer properties and led to materials with superior properties suitable for several industrial applications.Artigo IPEN-doc 22437 Electron-beam irradiation effect on thermal and mechanical properties of nylon-6 nanocomposite fiber infused with diamond and diamond coated carbon nanotubes2016 - IMAM, MUHAMMAD A.; JEELANI, SHAIK; RANGARI, VIJAYA K.; GOMES, MICHELLE G.; MOURA, ESPERIDIANA A.B.Artigo IPEN-doc 19383 Biodegradable aliphatic aromatic copolyester/corn starch blend composite reinforced with cofee parchment hush2013 - SILVA, VALQUIRIA A.; TEIXEIRA, JACIELE G.; GOMES, MICHELLE G.; ORTIZ, ANGEL V.; OLIVEIRA, RENE R.; SCAPIN, MARCOS A.; COLOMBO, MARIA A.; MOURA, ESPERIDIANA A.B.Artigo IPEN-doc 19381 Sugarcane bagasse ash reinforced HDPE composites: effects of electron-beam radiation crosslinking on tensile and porphological properties2013 - TEIXEIRA, JACIELE G.; GOMES, MICHELLE G.; OLIVEIRA, RENE R.; SILVA, VALQUIRIA A.; SARTORI, MARIANA M.; ORTIZ, ANGEL V.; MOURA, ESPERIDIANA A.B.Artigo IPEN-doc 19365 Influence of electrom beam irradiation on PP/Piassava fiber composite prepared by melt extrusion process2013 - GOMES, MICHELLE G.; FERREIRA, MAIARA S.; OLIVEIRA, RENE R.; SILVA, VALQUIRIA A.; TEIXEIRA, JACIELE G.; MOURA, ESPERIDIANA A.B.
