An Approach to Modelling the Manufacturing Process of Thermoset Composite Reinforced with 3D Woven

Abstract

This paper proposes the general approach to modelling the manufacturing process of thermoset composite reinforced with 3D woven based on the digital twin concept. The focus is on the methodology for determining the permeability of a dry 3D woven. Simulation results in ANSYS CFX are presented. Also, a curing simulation technique in ABAQUS with user subroutines for a thermosetting composite is described. The results of curing simulation for the Kamal-Sourour model are presented in more detail and the prediction of shape distortion for a composite U-shaped part as a result of chemical shrinkage and thermal expansion is performed.

Method for residual strain modeling taking into account mold and distribution of heat transfer coefficients for thermoset composite material parts

“…These formulas include inplane and through-thickness thermal and isothermal chemical shrinkage, temperature change, and initial angle. In [7][8][9], curing simulation methods is presented, when interaction between part and mold is imitated with using constraints. In [10][11][12], Svanberg studied three different boundary conditions: freestanding for imitation of mold which is very soft compared to the composite; fully constrained part for rigid mold imitation; and with frictionless contact conditions between part and mold.…”
