About

Jiahai Zhang is a leading researcher in advanced composite manufacturing, specializing in robotic fiber placement and variable-angle trajectory design for high-performance laminates. His work focuses on optimizing the mechanical and modal characteristics of carbon fiber-reinforced thermoplastics, particularly CF/PEEK composites, which are critical for aerospace and automotive applications. Zhang’s major contributions include demonstrating that variable-angle trajectory structures offer a significantly larger design space than traditional fixed-angle methods, enabling tailored stiffness and strength. His 2022 study on the effect of variable-angle trajectories on mechanical performance (12 citations) provides a systematic comparison of common design curves, offering practical guidance for improving laminate strength. Additionally, his 2021 work on modal characteristics and manufacturing methods for variable stiffness facesheets in sandwich plates (7 citations) advances the understanding of how robotic fiber placement can enhance vibration performance. These studies have been cited for their impact on lightweight structural design and automated manufacturing. Zhang’s research bridges computational modeling and experimental validation, providing engineers with actionable insights for next-generation composite structures. His achievements underscore his role in pushing the boundaries of robotic fiber placement technology, making him a key figure in the field of advanced composites.
