G-10 is a high-performance glass epoxy composite that has become indispensable across a wide range of industries due to its exceptional strength, durability, and resistance to environmental factors.

This fiberglass-based laminate combines lightweight construction with outstanding mechanical and electrical properties, making it a preferred material for applications ranging from electrical insulation to structural components in aerospace, marine, and consumer goods.

What is G-10?

G-10 is a composite material composed of woven fiberglass fabric impregnated with epoxy resin. The epoxy resin acts as a binder, curing under heat and pressure to create a rigid, durable material. This manufacturing process results in a laminate that is resistant to moisture, chemicals, and mechanical stress while maintaining a low weight.

G-10's non-conductive and non-corrosive properties make it particularly useful for applications in harsh environments or where electrical insulation is critical. Compared to other synthetic materials, such as phenolics or basic fiberglass, G-10 offers superior performance, including higher mechanical strength, better dimensional stability, and improved resistance to wear and degradation.

Key Properties of G-10

G-10 is renowned for its exceptional performance across a variety of demanding applications. Its strength, durability, and resistance to environmental factors make it a standout material for structural, electrical, and precision uses.

Below are the key properties that define G-10's versatility and reliability:

How is G-10 Made?

The production process of G-10 begins with the creation of prepreg, a pre-impregnated fiberglass fabric coated with a mixture of epoxy resin, fibers, and a hardener. This prepreg is then layered to the desired thickness and subjected to high heat and pressure, curing the resin and fusing the layers into a cohesive sheet.

The result is a rigid, dimensionally stable composite with consistent properties throughout its structure. The precise control of temperature and pressure during manufacturing ensures that G-10 exhibits minimal voids, exceptional uniformity, and excellent performance under stress.

Applications of G-10 Across Industries

G-10’s versatility allows it to serve various industries and applications. In the electronics sector, it is a primary material for printed circuit boards (PCBs) and insulators due to its dielectric strength and resistance to electrical breakdown. High-voltage equipment such as transformers and switchgear also benefit from G-10’s insulating capabilities.

G-10’s lightweight construction, combined with its resistance to corrosion and mechanical stress, makes it invaluable in aerospace and marine applications. It is commonly used for structural panels, instrument housings, and electrical components. The material’s ability to withstand harsh environments ensures long-term reliability in these demanding fields.

G-10 is also a favored material in consumer goods manufacturing. Its strength, customizability, and resistance to wear and moisture make it ideal for high-use items. Additionally, its non-conductive and spark-resistant properties are essential in power generation and industrial settings, where safety and performance are very important.
