A numerical integrated flow-stress processing model for plain weave textile composites.

ABSTRACT: This work proposes a numerical integrated flow-stress processing model in order to simulate the flow front of the resin and manufacturing-induced deformation during the fabrication cycle. In the flow model, each layer of the dry fiber fabric is modeled as an orthotropic porous material. The resin flow behavior is predicted using the volume of fluid method, incorporating the temperature- and cure-dependent viscosity of the resin. After the infusion model, the resin filling factor and the degree of cure are transferred to a multi-physics curing model to predict the residual stress. In this model, each lamina is modeled as a homogeneous orthotropic material with mechanical properties calculated from the in-situ resin modulus and the elastic modulus of the fiber based on the micromechanics.
