Phenolic resin is a common synthetic resin whose main components are phenol and aldehyde compounds. It has excellent properties such as abrasion resistance, temperature resistance, electrical insulation and chemical stability. The combination of phenolic resin and glass fiber forms a composite material that combines the advantages of phenolic resin and glass fiber. Phenolic fiberglass is a strong and versatile composite material made from a combination of phenolic resin and glass fiber reinforcement. It has excellent heat resistance, flame retardancy and high impact strength, making it valuable in many industries.

What is phenolic glass fiber?

Phenolic glass fiber is made by adding glass fiber reinforcement to a phenolic resin matrix. The phenolic resin has excellent heat and flame resistance, while the glass fiber reinforcement greatly increases strength, stiffness and impact resistance. The combination of the two makes the composite durable and able to withstand harsh conditions.

The phenolic glass fiber manufacturing method generally includes the following steps:

• Pre-treatment of glass fibers: The glass fibers are treated to remove impurities and improve their ability to bond with the resin.
• Resin Preparation: Phenolic resin is mixed with additives in a certain ratio to prepare the resin matrix.
• Fiber Reinforcement: The pre-treated glass fibers are impregnated, covered or injected with the resin matrix to fully combine the glass fibers with the resin.
• Curing: Aldehydes in the resin matrix react with the added curing agent to cure and mold the composite material.

Key features and benefits

•  High impact resistance: the material is very durable and is able to absorb sudden forces without compromising its structural integrity.
