Mechanical and thermal properties of polypropylene composites with curaua fibre irradiated with gamma radiation. In: INTERNATIONAL NUCLEAR ATLANTIC CONFERENCE; MEETING ON NUCLEAR APPLICATIONS, 9th; MEETING ON REACTOR PHYSICS AND THERMAL HYDRAULICS, 16th; MEETING ON NUCLEAR INDUSTRY, 1st, September 27 - October 2, 2009, Rio de Janeiro, RJ. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/11978.http://repositorio.ipen.br/handle/123456789/11978Thermal 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.openAccesscalorimetrycomposite materialselongationexperimental datagamma radiationpolypropyleneradiation dosesradiation effectsrupturesscanning electron microscopytensile propertiesthermal gravimetric analysisTexto completo de eventohttps://orcid.org/0000-0002-1737-3191https://orcid.org/0000-0002-7626-880X
