Rheological behavior of bamboo fiber compound plastic

摘要

Rheological characteristics of bamboo fiber compound plastic were examined experimentally. In the present study, rheological data for the shear viscosity, the storage modulus and the loss modulus of compound plastic of polypropylene with maleic acid mixing with various contents of bamboo fiber, were reported in comparison with equivalent glass fiber compound plastic. According to SEM visual information, bamboo fibers have short rod-like structure with high fiber-fiber interaction in the compound, while the glass fibers have long needle structure forming entanglement in the compound. It was obtained that the rheological data showed clear difference based on the different structures in the compounds. Rheological characterization was achieved by considering the natural bamboo fiber-fiber interaction, with which a rheological correlation is derived based on data obtained in the present investigation.
