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
