Epoxy Fiberglass Laminate Features:

1. High Strength

G11 Epoxy Fiberglass Laminate has excellent mechanical properties. Its tensile strength can reach 63,000 psi, its compressive strength is 37,000 psi, and its bending strength is as high as 75,000 psi. This high strength property comes from the close combination of glass fiber and epoxy resin. Glass fiber, like steel bar, provides strong support for the material, making it stable when subjected to heavy loads or stress, and not easy to deform or break.

2. High temperature resistance

G11 Epoxy Fiberglass Laminate has good heat resistance. Its glass transition temperature (Tg) can reach 135℃, and it can still maintain good mechanical properties and dimensional stability in high temperature environment. This heat resistance is due to the thermal stability of epoxy resin and the heat resistance of glass fiber, so that it can be used reliably in high temperature components of electronic equipment and high temperature working conditions of machinery, and will not show performance degradation or damage due to temperature increase.

3. Corrosion resistance

G11 Epoxy Fiberglass Laminate has good corrosion resistance. It has strong tolerance to a variety of chemicals such as acids, alkalis, and salts. After being immersed in a solution of a specific concentration of sulfuric acid, hydrochloric acid, sodium hydroxide, etc. for 24 hours, its mass loss rate is only 0.20%, which is much lower than other common materials. This corrosion resistance makes it perform well in the corrosive environment components of chemical equipment and electronic equipment, which can effectively prevent the material from being corroded and damaged, and extend its service life.

4. Easy processing

G11 Epoxy Fiberglass Laminate has good mechanical processing performance. It can be easily processed by cutting, drilling, milling and other processing operations. During the processing, the material is not prone to defects such as burrs and cracks, and the processing accuracy is high. The roughness of its processed surface can reach 1.6μm, which can meet the requirements of high-precision processing. This good processability allows it to be customized according to different application requirements, and it is convenient to manufacture components of various shapes and sizes.

5. Environmental compliance

G11 Epoxy Fiberglass Laminate fully meets the requirements of the EU RHOS standard and SGS standard. These standards have strict restrictions on the content of harmful substances in the materials, such as the content of heavy metals such as lead, mercury, and cadmium are all less than 100ppm. This shows that the material will not cause harm to the environment and human health during production, use, and disposal, conforms to modern environmental protection concepts, and can be safely used in various occasions with strict environmental protection requirements.

6. Dimensional stability

G11 Epoxy Fiberglass Laminate has high dimensional stability. Its linear expansion coefficient is only 1.5×10⁻⁶/℃, and the dimensional change is minimal when the temperature changes. This stability is derived from the low expansion characteristics of glass fiber and the cured structure of epoxy resin, which makes it perform well in applications with high dimensional accuracy requirements such as precision mechanical parts and insulating parts of electronic equipment, and can ensure the precise operation and stable performance of the equipment.

7. Good insulation performance

G11 Epoxy Fiberglass Laminate has excellent insulation performance. Its volume resistivity is as high as 2.0×10⁸Ω·cm and its surface resistivity is 2.0×10⁶Ω, which can effectively prevent current leakage. This good insulation property enables it to reliably isolate components with different potentials when used as an insulating component in electrical equipment, prevent short circuits and leakage accidents, and ensure the safe operation of the equipment.

8. Lightweight and high strength

G11 Epoxy Fiberglass Laminate has high strength and a relatively low density of only 1.82g/cm³. This light weight and high strength feature gives it a unique advantage in fields such as aerospace and automobiles that have strict weight requirements. It can reduce the weight of equipment without reducing strength, and improve the energy efficiency and performance of equipment.
