WHAT IS G11 GLASS EPOXY COMPOSITE?

 
G11 is a high-temperature, thermoset industrial fiberglass laminate made from filament glass cloth and an epoxy resin binder, is a fiberglass-epoxy composite material. It has the characteristics of high temperature resistance, high mechanical strength, good insulation and corrosion resistance.Applications: Commonly used in aerospace equipment, electrical systems, medical devices, and other high-performance applications.
G11 is similar to G10 but offers better performance at higher temperatures and improved insulative properties. It’s available in sheet, rod, and tube forms and can be machined using standard tools.

HOW IS G11 MADE?

G11 glass epoxy composite is manufactured through a process that involves layering glass fabric sheets and saturating them with an epoxy resin. Here’s a step-by-step overview of the process:
 
1.Layering: Multiple layers of glass cloth are stacked together. The glass fabric used is specifically designed for high-temperature applications.
2.Saturating: The layers of glass cloth are then saturated with a high-temperature epoxy resin, ensuring each layer is thoroughly impregnated with the resin to enhance the material’s mechanical and insulative properties.
3.Curing: The saturated layers are subjected to controlled curing under high pressure. This step is crucial as it polymerizes the resin, bonding the layers into a solid, uniform sheet.
4.Finishing: After curing, the material is cooled and can be cut or machined into various shapes and sizes, such as sheets, rods, and tubes1.
The result is a robust composite material with exceptional durability, high mechanical strength, and excellent electrical insulation properties, suitable for a wide range of high-performance applications
