Fabric Sheets:
A Fabric Sheet (also called Fabric-Based Phenolic Laminate or Fabric Reinforced Phenolic Sheet) is an engineering plastic laminate made by impregnating layers of cotton fabric with phenolic resin and then compressing them under high pressure and temperature.
It is one of the oldest high-performance laminates, often called Fabric Bakelite because it is part of the Bakelite family of thermosetting plastics.
Main Grades of Fabric Sheets :
1. Fine Weave Cotton Fabric Phenolic (Grade F1 / F2 / F3)
- Made with fine cotton cloth
- Smooth finish, good machinability
- Used for gears, precision components, bushings
2. Special Grades (Modified Phenolic) :
- Oil-Resistant Fabric → Used for bearing cages, lubrication parts
- Heat-Resistant Grade → Better performance in high temperature
- Electrically Enhanced Grades → Improved insulation properties
Broad Engineering Applications :
1. Mechanical Engineering
- Gears & Gear Blanks → Quiet operation, non-sparking, and wear resistance.
- Bearing & Bushes → Acts as a self-lubricating bearing in machines.
- Clutch & Brake Parts → Withstands friction and reduces noise.
- Guides & Rollers → High load-bearing capacity and long life.
2. Electrical Engineering
- Insulating Plates & Boards → Strong dielectric properties, safe for switchgear.
- Terminal Blocks & Insulators → Non-conductive, heat-resistant.
- Transformer & Motor Components → Prevents current leakage and withstands high temperatures.
3. Automobile & Transport Industry
- Brake Pads, Clutch Plates & Linings → Shock resistance and durability.
- Support Plates in Engines → Vibration damping, mechanical strength.
4. Textile & Printing Machinery
- Spacers, Rollers & Bearings → Withstand wear, friction, and continuous operation.
- Gear Wheels → Smooth and silent working.
5. Chemical & Process Industry
- Pump Components → Resistance to mild chemicals and oils.
- Sealing Parts → Good stability against solvents and lubricants.
6. Marine & Defense
- Non-sparking Components → Safe for explosive/flammable environments.
- Insulating Structural Parts → Lightweight and resistant to moisture.
7. General Engineering
- Fixture Plates, Jigs & Tools → Easy to machine and durable.
- Spacer Washers, Flanges → Strong and dimensionally stable.
