Fiber Sheets and Rods

Description

A phenolic fiber sheet is a composite material made from layers of fabric coated with phenolic resin, heated, and pressed under high pressure. Phenolic resin is made from phenol and formaldehyde, which are bonded together to form large molecules.

Phenolic fiber sheets are strong, durable, and lightweight, making them a good alternative to metal in many applications. They are often used in industrial settings, and can be made with a variety of fabrics, including paper, cotton, and glass.

Some applications for phenolic fiber sheets include:

• Electrical and mechanical parts: Phenolic fiber sheets are used to make parts that are subject to reversed electrical and mechanical stresses, or that work under friction.
• Insulating material: Phenolic fiber sheets can be used as an insulating material in transformer oil, or in the air at normal relative humidity and a frequency of 50 Hz.
• Construction material: Phenolic fiber sheets can be used as a construction material.

Phenolic fiber sheets have many properties, including:

• Heat resistance

Phenolic fiber sheets can withstand a wide range of temperatures and humidity.

• Water resistance

Phenolic fiber sheets have low water absorption and high water dissipation, making them suitable for watercraft and similar applications.

• Impact resistance

Phenolic fiber sheets have good abrasion resistance and can be molded into a variety of shapes and sizes.

• Corrosion resistance

Phenolic fiber sheets resist corrosion from common chemicals.

• Electrical resistance

Phenolic fiber sheets have superior electrical characteristics over a wide range of temperatures and humidity.

• Machinability

Phenolic fiber sheets are easy to saw, drill, tap, and machine with ordinary tools.

• Dimensional stability

Phenolic fiber sheets have good dimensional stability.

• Strength

Phenolic fiber sheets have high mechanical resistance, high tensile strength, and high compressive strength.

• Lightweight

Phenolic fiber sheets are lightweight, making them easier to transport and install.

Phenolic fiber sheets are used in a wide range of mechanical and electrical applications.
