Introduction
GFRP (Glass Fiber Reinforced Plastic) is a composite material that combines glass fiber and resin, and is characterized by its lightweight yet high-strength properties. It also has excellent corrosion resistance and electrical insulation properties, and is used in many fields. This column describes the features and applications of GFRP products.

Features of GFRP
Lightweight and high strength: Compared to steel and aluminum, GFRP is lightweight, yet has high strength.
Corrosion resistance: Little degradation due to chemicals and moisture, and can be used in outdoor and marine environments.
Electrical insulation properties: Because it does not conduct electricity, it is suitable for electrical and electronics-related applications.
Free formability: Easily fabricated into various shapes, allowing for a high degree of freedom in design.
Main applications of GFRP products
Building and civil engineering fields
Bridge members, durable roofing materials, soundproof walls, reinforcement materials.
Shipbuilding and Automotive Fields

industrial machinery and equipment field
chemical plant tanks and piping, cooling tower components.
electrical and electronics field
insulation components, switchboard covers, antenna components.
Summary
GFRP is used in many industries because of its durability, light weight, and formability.In particular, GFRP products are the best choice in environments where corrosion resistance is required more than metals.
As technology continues to evolve, we expect to see the development of more highly functional GFRP products in the future.
