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.425-432closedAccesselectron beamsirradiationnanocompositesnanomaterialsclaysfiberspolymerspolyethylenesComparison between HDPE/clay and HDPE/piassava fiber/clay treated by electron beam radiationTexto completo de evento10.1002/9781118659045.ch49https://orcid.org/0000-0003-3546-1643
