What are the properties of fiberglass materials?

When fiberglass is used as a reinforcing material for reinforced plastics, its biggest feature is its high tensile strength. The tensile strength is 6.3~6.9 g/d in the standard state and 5.4~5.8 g/d in the wet state. Density 2.54g/cm3. It has good heat resistance and its strength remains unchanged when the temperature reaches 300°C. In addition, fiberglass also has excellent electrical insulation properties and is widely used in thermal insulation materials and fire shielding materials. However, its nature is brittle and its wear resistance is poor.
