As the demand for composite materials in the rail transportation industry increases, the layout of international standards is becoming more and more important. While existing standards provide more complete guidance on material performance and safety, future standard-setting needs to be better adapt

The use of composite materials in rail transportation has rapidly increased. Composites are now widely used in structural components, carriages, seats, and interior fittings, significantly reducing weight, improving fuel efficiency, and greatly lowering maintenance costs. Given the wide variation in

Resin Transfer Molding (RTM) is a typical liquid molding process for fiber-reinforced resin matrix composites. The process mainly involves:1. Designing a fiber preform according to the shape and mechanical property requirements of the desired part.2. Placing the designed fiber preform into the mold,

Thermosetting resin technology is mature and stable, making it the current mainstream matrix resin for prepregs. With breakthroughs in high-performance carbon fiber varieties and quality, as well as advancements in composite material structural design and manufacturing technology—especially with the
