A Review of Welding Technologies for Aerospace-Grade Thermoplastic Composites: Developments Since the 2012 Benchmark Study

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com]Published : December 01 , 2025 Abstract Thermoplastic composites (TPCs) have advanced from niche usage to mainstream aerospace candidates due to their recyclability, weldability, and reduced manufacturing costs compared with thermoset systems. Welding technologies—ultrasonic, induction, resistance, infrared, laser, and microwave—enable solvent-free, fast assembly of high-performance

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
