Abstract

Insulated rail joints are one of the most important components of the railroad and their
failure, deals a massive financial loss for our country. Usually, these joints are bearing
different dynamic and quasi-static loads such as tensile load and bending moment. In this
research, design and construction of insulated rail joints from composite material was
examined. The composite epoxy/glass fiber was chosen for insulated rail joints based on the
failures accrued for conventional joints. To evaluate the mechanical properties of composite
samples, the tension, 3 point bending and hardness experiments were carried out based on
ASTM standards. The results showed that the improvement of mechanical and flexural
strength of composite joints in comparison with conventional joints. In addition, the
estimated cost of composite sample was decreased by 40 percent to European companies.
