Numerical modeling of thermoplastic composite materials automated processing methods processes

Abstract

In the framework of this work, a numerical study was carried out to calculate a thermoplastic prepreg processing parameters for layers layup using an automated method. Physical and mathematical models determining automated processing methods regimes were formulated. Numerical experiments were carried out to simulate the heat distribution while laying of a thermoplastic prepreg tape on metal and carbon fiber molds. In the numerical experiments, a thermoplastic composite material with a PEEK matrix (polyetheretherketone) was considered. As a result, temperature distribution fields were obtained for the mold tools and the tape made of thermoplastic composite materials. It was revealed that when using the metal mold, a significant heat removal from the heated thermoplastic prepreg tapes were observed. Based on the obtained simulation results, the mold tool for automated thermoplastic prepreg tapes layup should be made of carbon-fiber composite material on a high-temperature binder.
