Learn about G10 epoxy fiberglass laminate

In today’s rapidly developing industries, the performance requirements for insulation materials are getting higher and higher. G10 epoxy fiberglass laminate has become the material of choice in many industries due to its excellent insulation and mechanical properties.

What is G10 epoxy fiberglass laminate?

G10 epoxy fiberglass laminate is a composite material composed of glass fiber cloth and epoxy resin. “G” stands for glass fiber, and “10” means that the content of glass fiber in it is 10%. The colors are generally black, red, blue, green and so on. Originally developed for aircraft use, it can withstand extreme forces without deformation. The material is insulating, resistant to acid and alkali. And it is impermeable to moisture or liquid penetration and it is light in weight. These properties make G10 epoxy fiberglass laminate the ideal choice for electronic, aerospace, chemical industry, precision instrument manufacturing and many other fields.

Key features of the G10 epoxy fiberglass laminate

Mechanical property

G10 epoxy fiberglass laminate has high mechanical strength. Its laminar-bending strength can reach 45ksi in longitudinal direction and 35ksi in transverse direction, which is significantly higher than that of ordinary epoxy sheet‌. In addition, it also has good impact resistance and hardness. So it can withstand greater external forces and is not easy to damage‌.

Electrical performance

G10 epoxy fiberglass laminate has very high dielectric strength and low dielectric constant, which is suitable for high voltage and high frequency circuit insulation material. It can maintain good insulation performance in both dry and wet state to ensure the safety and stability of power transmission‌.

Thermal performance

The G10 epoxy fiberglass laminate can operate for long periods of time up to 155°C. And it is suitable for applications in high temperature environments‌. In addition, it has good dimensional stability and minimal dimensional change under different temperature and humidity conditions, which makes it favored in precision instrument manufacturing‌.

Chemical property

G10 epoxy fiberglass laminate has good chemical corrosion resistance and moisture resistance. So it can maintain stable performance in harsh environments such as acid and alkali. This makes it commonly used in the chemical industry to make corrosion-resistant parts‌.

The application of G10 epoxy fiberglass laminate

1.Electrical field

Insulation parts:

Because of its good insulation properties, G10 epoxy fiberglass laminate is often used as an insulating part of various electrical equipment. For example, in electrical equipment such as circuit breakers, switchgear, transformers, GG10 epoxy fiberglass laminate is often used as safety baffles, safety shields, spacers, interphase partitions, etc., to ensure that current does not leak or cause short circuits.

Structural support:

G10 epoxy fiberglass laminate has high mechanical strength and rigidity, and can withstand certain load and vibration. Therefore, in electrical equipment, it is often used as structural support components, such as bus splints, support frames, etc., to ensure the overall structural stability and reliability of the equipment.

Electrical connector:

In some electrical connection parts, G10 epoxy fiberglass laminate can be used as a substrate for connecting parts, providing stable support and insulation properties. For example, in the position of motor armature parts, movable cover plates, slot wedges, etc., G10 epoxy fiberglass laminate can be used as substrates or fasteners for these parts to ensure the reliability and safety of electrical connections.

2.Electronic field

Printed Circuit Board (PCB) :

G10 epoxy fiberglass laminate is one of the core materials of printed circuit board. Due to its good insulation properties, mechanical strength and dimensional stability, G10 epoxy fiberglass laminate is often used as a substrate material for PCB to support the installation and connection of electronic components.

Electronic equipment housing:

G10 epoxy fiberglass laminate is also often used to make some electronic equipment housing. Due to its excellent corrosion and weather resistance, the G10 epoxy fiberglass laminate is able to protect the interior of electronic devices from the erosion of the external environment. At the same time, it can provide enough strength and stiffness to support the overall structure of the device.

In addition, G10 epoxy fiberglass laminate is also widely used in rail transit, new energy vehicles, chemical industry, aviation and aerospace fields. With the continuous advancement of technology and the increasing demand for high-performance materials, G10 epoxy fiberglass laminate is expected to be applied in more emerging fields.
