Resumo
Thermal and mechanical behavior of polypropylene with curaua fibre composites were investigated. The
treatment of the curaua fibres was processed in alkaline solution (10% wt NaOH). A coupling agent was used
(maleic anhydride) to increase the adhesion of the fibre/matrix interface. This composite was irradiated with
gamma source in the doses of 5, 15 and 30 kGy and the adhesion between the fibres and the polymeric matrix
was monitored to observe probable changes. The thermal behavior was evaluated using differential scanning
calorimetry (DSC) and Thermogravimetry (TGA). The mechanical behavior was evaluated using tensile
strength in comparition with non-reinforced polypropylene resin. The morphology of the composite fracture
surface was observed using scanning electron microscopy (SEM). There were no significant changes in the
thermal properties neither in the adhesion of irradiated fibres at doses of 5, 15 and 30 kGy of gamma radiation.
