Cementitious composite manufactured by extrusion technique
This paper presents the results of theoretical and experimental studies of short fiber-reinforced composite manufactured by extrusion. The cementitious composite in the extruder is considered a nonlinear viscoelastic fluid. By studying the key parameters of such a fluid, a general nonlinear viscoelastic constitutive model is introduced, in which the effects of the normal stresses are taken into account. The flows in an extruder are assumed to be two-dimensional steady shear flows. The differential equations of a flow motion are solved numerically by a finite difference method. The flow volume rate for a nonlinear viscoelastic fluid is predicted and compared with the experimental data.
