Process Simulation

Today, process simulation plays a crucial role in composite manufacturing science. It helps us understand, refine, and optimize the processes we use to make composite parts. At IVW, process simulation is focused on four key topics: processing of thermoplastic sheet materials, liquid composite molding, welding of thermo- plastic composites by induction, and the processing of bulk molding and structural molding compound materials.

Process simulation begins with material characterization, a procedure of defining and measuring the material’s behavior, usually deformation or flow as well as thermal behavior, experienced under the specific conditions during manufacturing. In most cases temperature, strainrate, pressure, and time are the key parameters. The experiments provide the source of input and form of verification required for computer simulations which can then be performed in place of physical experiments using mathematical and engineering software, essentially allowing what engineering software providers have termed “virtual manufacturing”.
