Squeezed sponge model

Two matrix flow submodels have been proposed the sequential compaction model [15] and the squeezed sponge model [11], Both flow models are based on Darcy s Law, which describes flow through porous media. Each composite layer is idealized as a fiber sheet surrounded by thermoset resin (Fig. 13.9). By treating the fiber sheet as a porous medium, the matrix velocity iir relative to the fiber sheet is given as (Eq. 13.5) ... [Pg.402]

In the squeezed sponge model [11,13], compaction is not necessarily sequential and the applied pressure is shared by both the matrix and the fiber bed. The fiber bed behaves as a rapidly stiffening nonlinear spring. Pressure in the fiber bed is a function of fiber bed compaction. The rate of change of the fiber volume fraction is related to the pressure drop... [Pg.403]
