Abstract
We have studied the effect of types and shapes of fiber on steady shear flow properties of fiber reinforced plastics. In the present paper, we measured the viscosity under steady shear flow of various polymeric melts using a Koka type flow tester. Sample melts were glass fibers reinforced nylon 6, carbon fibers reinforced nylon 6, plaster whisker fibers reinforced nylon 6, plaster whisker fibers reinforced nylon 66 and mica reinforced nylon 6. It was found that the viscosity of polymeric melts with the dispersed fibers depends on the distribution of fiber length, aspect ratio of the fibers, the molecular weights of the polymers and the surface property of contained fibers.
We obtained experimentally the coefficients of both Carreau model and WLF equation on the nylon 6 melts with the dispersed plaster whisker fiber, glass fiber, carbon fiber and mica.
