Abstract
The associated problem of the rheology of a thermoplastic polymer melt during the pultrusion of fiber-reinforced composites in a plane-slotted die is resolved. The permeabilities of a stochastic fibrous system are determined for the case of a nonlinear (exponential) rheological model of the melt. The pressure distribution in the pultrusion tool is calculated with allowance for the permeability of the fibrous system. The dependence of the pultrusion force on the viscous properties of the melt and on the pull rate of the fibrous layer is established.
