Increasing reliability while reducing component cost and weight.
These objectives can be met by replacing metal or cast components with high performance thermoset composite materials. Norplex-Micarta offers a full line of these composites in sheet, tube, rod and pre-preg forms that are certified to meet the most challenging rail and mass transit requirements. From braking systems to electrical insulation components for subway cars, Norplex-Micarta is the preferred high performance composites manufacturer for OEMs and fabricators around the world.
Norplex-Micarta Composite Materials provide excellent mechanical strength at a relatively low weight.
Light-weight components must exhibit excellent tensile, compressive, shear and flexural strength. They must also withstand the initial impact force of installation, as well as the repeated stress of inspection and repair. Creep resistance is also an important performance criteria; Norplex-Micarta composites exhibit excellent creep resistance, making them a good alternative to standard thermoplastics.
Norplex-Micarta composites offer insulation properties when used as an electrical barrier between metal parts. They also feature low toxicity/burn characteristics critical for applications in mass transit applications. Some materials are self-extinguishing to minimize damage in the case of fi re or explosion.
Thermoset Composites as Railroad and Subway Supports
Norplex-Micarta composites provide electrical insulation for motor mounts, generator mounts and surrounding electrical equipment used for railroads. For subway applications, composites provide electrical insulation between the car and the electrical current running from the third rail to the motor.
