The general modeling methodology for thermoset composite reinforced with 3D woven is described. In this study the focus is on the curing simulation и prediction of shape distortion for thermoset composites in ABAQUS with user subroutines. The procedure of homogenization and determination of effective properties of a thermoset composite reinforced with 3D woven for the rubbery and glassy state of the matrix is also described in detail. Depending on the thermoset polymer type, the different cure reaction formulations are implemented. The temperature expansion and chemical shrinkage tensors at each time step are set depending on the degree of cure and the glass transition temperature. Curing model with piecewise constant elastic modules is used. The model takes into account the shape distortion of the part due to chemical shrinkage and thermal expansion of the material. Curing simulation and prediction of shape distortion results for U-shaped part for Kamal-Sourour reaction type is presented. The effective properties of the composite reinforced with 3D woven for the rubbery and glassy states of the matrix are obtained.
