Compósitos de polipropileno com 10, 20 e 30% em volume de fibra de coco verde foram obtidos em câmara de mistura Haake, tendo como variáveis a temperatura de processamento e a velocidade de cisalhamento. O módulo de flexão e as características morfológicas dos diferentes compósitos obtidos foram avaliados e comparados com o polipropileno puro. Foi observado que a temperatura de 170 °C, a velocidade do rotor de 60rpm e o teor de fibra de coco verde de 30% forneceram o melhor desempenho quanto à flexão. Essas observações foram comprovadas pela análise da morfologia. Polypropylene composites containing 10, 20 and 30% in volume of green coconut fiber were prepared in a Haake chamber at various processing temperatures and shear rates. The flexural modulus and morphological characteristics of the composites were evaluated and compared with pure polypropylene. Optimization experiments indicated that a temperature of 170 °C, shear rate of 60rpm and green coconut fiber content of 30% showed the best properties by flexural modulus. These observations were confirmed by a morphology analysis
