Resumo
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.
