The global transportation industry is in a critical period of rapid development and transformation. With the advancement of energy conservation, emission reduction, green travel, and intelligent technologies, higher requirements have been put forward for transportation materials: lightweight, high strength, durability, recyclability, and easy processability. While traditional metal materials offer high strength, they are heavy, costly, and prone to corrosion; ordinary plastics and composite materials, on the other hand, have limitations in terms of strength and durability.
As a new type of high-performance composite material, CFRT (Continuous Fiber Reinforced Thermoplastic) thermoplastic composite panels are demonstrating broad application prospects in the transportation field, thanks to their characteristics such as high specific strength, lightweight, corrosion resistance, thermoplastic processability, and recyclability. From automobile bodies to rail transit, from aerospace structural components to ship lightweight design, CFRT thermoplastic composite panels are becoming an important driving force for material upgrading in the industry. This article will systematically analyze the applications, technical advantages, manufacturing processes, economic and environmental benefits, as well as future development trends of CFRT in the transportation sector.
