Abstract
Polymer matrix composites exhibit excellent mechanical properties, corrosion resistance, and design flexibility, presenting broad application prospects in chemical engineering equipment. This study aims to investigate the potential applications and performance optimization strategies of polymer composites in chemical equipment to address issues associated with traditional me tallic materials, such as susceptibility to corrosion and high weight. By integrating experimental research with numerical simulation, a systematic analysis was conducted on the corrosion resistance, mechanical characteristics, and thermal stability of various types of polymer composites under acidic and alkaline conditions, along with material selection and structural design optimization tailored to typical operating conditions of chemical equipment. The results indicate that carbon fiber-reinforced composites possess superior strength and stiffness while significantly reducing equipment weight; glass fiber-reinforced composites demonstrate excellent chemical corrosion resistance, making them suitable for complex working environments. Furthermore, the incorporation of nanofiller modification technology has enhanced interfacial bonding and anti-aging properties, providing an effective approach to extending equipment service life. An innovative aspect of this research is the development of a multiscale reinforcement mechanism-based material design method, which achieves comprehensive performance improvement of polymer composites and has been successfully applied in actual chemical equipment, verifying its reliability and cost-effectiveness. This work lays the foundation for promoting the lightweight and efficient development of the chemical industry..
