What are the main characteristics of fiberglass composites?

1. Excellent mechanical properties. The tensile strength of fiberglass composites is lower than that of steel, but higher than that of ductile iron and concrete, while the specific strength is about 3 times that of steel and 10 times that of ductile iron.

2. Good corrosion resistance. Through reasonable raw material selection and scientific thickness design, fiberglass composites can be used for a long time in organic solvent environments such as acid, alkali, and salt.

3. Good thermal insulation performance. fiberglass composites have the characteristics of low thermal conductivity and are excellent thermal insulation materials. Therefore, under the condition of small temperature difference, no special insulation is required to achieve good thermal insulation effect.

4. Small thermal expansion coefficient. Due to the small thermal expansion coefficient of fiberglass composites, they can be used normally under various harsh conditions such as surface, underground, seabed, high cold, and desert.

5. Excellent electrical insulation. It can be used to make insulators. It can still maintain good dielectric properties at high frequencies. It has good microwave transmittance and is suitable for use in power transmission and minefields.
