Sleeper ilchodach iarnróid
Composite rail sleepers refer to sleepers made of composite materials, which are used to support railway tracks. Compared with traditional wooden sleepers, concrete sleepers and steel sleepers, composite sleepers have longer service life, better durability and lower maintenance costs. They are usually made of reinforcing materials such as glass fiber and carbon fiber and matrix materials such as resin, and have the characteristics de neart ard, meáchan éadrom agus friotaíocht creimthe .
