Carbon Fiber Subway Car Prototype Released: What it means for composites in the Infrastructure industry

Composite materials have been replacing the traditional materials used in the infrastructure industry, such as wood, steel and concrete, for the past several years. While these traditional materials provide a sturdy foundation for infrastructure builds, they wear down over time and require numerous repairs and maintenance compared to composite materials.

To save time on repairs and to extend the longevity of the structures, the Infrastructure industry has started replacing traditional materials with composites such as carbon fiber and epoxy, among others. These composite materials are resistant to corrosion and high temperatures, allowing them to maintain the structural integrity of the buildings or structures for a longer amount of time compared to traditional materials.


The first carbon fiber subway car prototype is presented to the Infrastructure industr

Carbon fiber has proven itself as one of the most beneficial composite materials to the Infrastructure industry due to its high tensile strength and low thermal expansion. CRRC Changchun Railway Vehicles, a leading Chinese train car maker, introduced the first carbon fiber subway train car to the Infrastructure industry. Because of its carbon fiber construction, the subway car is roughly 35% lighter than standard subway cars, which means it requires less energy to power the car.

Additionally, due to the advanced composite structure of the subway car, it is more durable and requires less maintenance than traditional subway cars, which adds great benefit to the Infrastructure industry.
