Vacuum-Assisted Induction Welding of Thermoplastic Composite Sandwich Panels: A Process–Structure–Property Study

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com] Abstract This paper presents a comprehensive reconstruction and reinterpretation of the vacuum-assisted induction welding (Vac-IW) process for assembling all-thermoplastic composite sandwich panels. Building upon the experimental observations of localized interface heating, hysteresis-based susceptors, and dual-polymer bonding architectures, this study analyzes how welding speed, susceptor
