Study and Reliability Evaluation of High-Performance Fiber-Reinforced Sealing Materials for New Energy Vehicles

The rapid development of the new energy vehicle industry has imposed stringent requirements on the reliability of core systems. As a key component of battery, motor, and electronic control systems, sealing materials directly affect the safety and service life of the entire vehicle. Traditional sealing materials have obvious shortcomings in high-temperature resistance, electrolyte corrosion resistance, and long-term aging stability, making them difficult to adapt to the complex working conditions of new energy vehicles. Fiber-reinforced composites, with their excellent mechanical properties and environmental adaptability, have become an important direction to break through the bottlenecks of traditional materials. The technical accumulation of Qingdao Eager High-Precision Plastic and Rubber Co., Ltd in die-cutting processing, precision molding, and polymer material modification provides a practical basis for the development of high-performance sealing materials. Its experience in material interface bonding, molding process optimization, and reliability testing can support the full-process research and development of fiber-reinforced sealing materials from formula design to practical application. Based on the sealing needs of new energy vehicles, this study combines precision processing technology and material modification experience to develop high-performance fiber-reinforced sealing materials suitable for key systems. Through performance testing and system reliability evaluation, it reveals the correlation mechanism between material properties and system stability, providing theoretical and practical support for the upgrading of new energy vehicle sealing technology.
