About the Book

A Phormium tenax é uma fibra natural de origem vegetal originária da Nova Zelândia e que se adapta ao clima equatorial, oceânico, subtropical e tropical. Neste trabalho ela foi usada como reforço na produção de materiais compósitos a base de polipropileno (PP). Com a intenção de usar este material para aplicações estruturais e semiestruturais, foram ensaiadas mecanicamente amostras de compósitos de PP reforçados com diferentes teores de fibras e em algumas delas na presença de uma lâmina de alumínio. As fibras usadas são in natura em comprimentos curtos, 5 mm, longos, 50 mm e contínuos (160, 125 e 63 mm) e os compósitos foram submetidos a ensaios de tração, flexão e impacto. Amostras foram confeccionadas em processos de extrusão e compressão e também só por compressão. A Phormium tenax, os compósitos, o PP e o polipropileno maleatado (PPMA) foram caracterizados química e termicamente. Análises morfológicas e mecânicas da Phormium tenax foram realizadas. Aspectos qualitativos foram avaliados nos compósitos. Resultados apontam para uma boa resistência mecânica da fibra em estudo, contudo não demonstram boa eficiência no reforço do PP, necessitando ajustes na obtenção dos compósitos.
