Application of G11 Epoxy Machined Components in Reactors

In fields such as nuclear power, chemical processing, and high-energy physics, reactors operate for long periods under extreme conditions, including high temperature, high pressure, high mechanical stress, and complex media environments. These conditions impose extremely stringent requirements on the safety and stability of internal structural materials. Thanks to their excellent heat resistance, electrical insulation performance, and structural strength, G11 epoxy glass fiber laminate machined components have become one of the important candidate materials for critical insulation and support parts inside reactors.

Overview of G11 Epoxy Machined Components

G11 is a high-performance laminated insulation material composed of an epoxy resin matrix reinforced with alkali-free glass fiber cloth. Compared with commonly used G10/FR4 materials, G11 can maintain stable mechanical and electrical properties even under elevated temperatures. Its thermal class can reach Class F (155 °C) or higher, making it suitable for industrial equipment with stringent thermal stability requirements.

Through CNC machining, waterjet cutting, precision milling, and other processing methods, G11 can be manufactured into various high-precision customized structural components. These parts are widely used in insulation and structural support systems within reactors.

Requirements for Insulation Materials in Reactors

The operating environment of reactors is highly complex, and materials are typically required to meet the following performance criteria:

The material must withstand long-term high-temperature operation with stable thermal aging performance.

The material must provide excellent electrical insulation to prevent partial discharge and electrical breakdown.

The material must have high mechanical strength and dimensional stability to endure vibration and mechanical stress.

The material must be resistant to chemical media and radiation environments.

The material must offer good machinability to meet the customization requirements of complex structural components.
