Multiphysics Modeling of Radiofrequency Heating of Carbon Fiber Composites

Abstract

Radiofrequency (RF) heating has become a vital technique in processing carbon fiber composites, especially for high-performance applications like aerospace. To understand how RF heating impacts these materials, we need to look at the interplay between electromagnetic fields, heat transfer, and mechanical stresses. Our research aims to create a detailedmodel that captures these interactions and accurately predicts temperature changes and mechanical responses in the composite material. Using established theories and validating our model through analytical solutions and finite element analysis (FEA), we aim to understand the effects of varying RF power, the role of carbon black fillers, and how the temperature-dependent behavior of epoxy resin impacts the process. By doing so, we hope to optimize material choices and ensure the stability and reliability of these composites in advanced manufacturing.
