Tufnol Materials and CNC Machined Components - Rail
Harsh, aggressive operating environments require materials that can meet these challenging conditions and provide optimum performance.
It is not surprising therefore that rail engineers around the world look to Tufnol material to cope with the extreme and arduous operating conditions, while at the same time meeting the safety and quality requirements demanded in this industry sector.
A typical application is the bogie pivot pads on railway carriages. These are manufactured from a hard wearing reinforcement of medium weave cotton fabric which utilises an advanced resin system with the addition of PTFE. The benefits of using this material are its superior wear resistance and elimination of the need for regular lubrication thereby creating savings in maintenance costs.
Low smoke properties are crucial in Underground facilities and tunnels. We have developed materials which give exceptional performance over and above standard phenolics.
Our specially formulated resin systems result in controlled flammability, good resistance to ignition and excellent low smoke and toxicity values, as well as electrical insulation.
We can offer these as machined components or sheets of pre-impregnated material.
Tufnol Composites can be used in Rail applications such as:
- Phenolic Cotton: Carp, Whale, Crow
- Phenolic paper: 1P13, Kite
- Glass Fabric Laminates: 10G/40, 10G/41, 6G/92
- Phenolic Glass; 10G/24
- Epoxy Cotton: 6F/45
- Special Bearing Grades: 2F/3/PTFE
All materials are applicable for all products, but key properties vary depending on specific application. All grades can be machined to your requirements. Enquire to find out more.
