G10 material, also known as garolite, is a high-pressure fiberglass laminate and a type of composite material. It is made by stacking multiple layers of glass cloth soaked in epoxy resin, then compressing the material under heat until the epoxy cures. This process creates a strong, stiff, and durable material that is manufactured in flat sheets most often a few millimeters thick. Key properties of G10 include:

• High strength and toughness (the toughest of the glass fiber resin laminates)
• Low moisture absorption
• Excellent electrical insulation
• High chemical resistance
• Dimensional stability under temperature and moisture conditions

G10 was originally used as a substrate for printed circuit boards because of its electrical and thermal insulating properties. Beyond this, it has found many other applications including knife handles, firearm grips, boating applications, insulators, jigs, fixtures, and various industrial and mechanical uses. Its characteristics make it a popular material for manufacturing durable, moisture-resistant, and lightweight components. It is also low maintenance and resistant to impacts, abrasions, and chemicals. Additionally, G10 can be produced in various colors and patterns, often used decoratively on knife handles and grips. In summary, G10 is a versatile composite material made from fiberglass and epoxy resin, known for its toughness, electrical insulation, moisture resistance, and dimensional stability, widely used in electronics, tooling, and outdoor equipment manufacturing.
