G10 composite is a high-pressure fiberglass laminate, a type of composite material [1]. It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures [2, 3]. It is manufactured in flat sheets, most often a few millimeters thick. G-10 is very similar to Micarta and carbon fiber laminates, except that glass cloth is used as filler material.
Key Facts
- Composition: G10 composite is created by stacking multiple layers of glass cloth, which are soaked in epoxy resin. The material is then compressed under heat until the epoxy cures.
- Properties: G10 composite is favored for its high strength, low moisture absorption, and high level of electrical insulation and chemical resistance. It maintains these properties even under humid or moist conditions.
- Uses: G10 composite has a wide range of applications. It is commonly used as a substrate for printed circuit boards, as well as for reinforcing the edges of fiberglass-coated wood. It is also used in the production of knife handles, gun grips, and other tools. Additionally, G10 composite can be used as a 3D printer build surface.
- Safety precautions: When working with G10 composite, it is important to take safety precautions. Cutting or grinding the material can release glass and epoxy dust, which can contribute to respiratory disorders. Proper ventilation and the use of masks or respirators are recommended.
Properties of G10 Composite
G-10 is favored for its high strength, low moisture absorption, and high level of electrical insulation and chemical resistance [1]. These properties are maintained not only at room temperature but also under humid or moist conditions. It was first used as a substrate for printed circuit boards, and its designation, G-10, comes from a National Electrical Manufacturers Association standard for this purpose.

Are there any safety precautions to take when working with G10 composite?
Yes, when working with G10 composite, it is important to take safety precautions. Cutting or grinding the material can release glass and epoxy dust, which can contribute to respiratory disorders. Proper ventilation and the use of masks or respirators are recommended.
Is G10 composite strong?
Yes, G10 composite is known for its high strength and durability. It is often used in applications where high strength and low weight are required, such as in the production of knife handles and gun grips.
Is G10 composite resistant to moisture?
Yes, G10 composite has low moisture absorption, which means that it can withstand exposure to moisture without losing its strength or other properties. This makes it a good choice for use in outdoor applications or in environments where moisture is present.
Is G10 composite electrically insulating?
Yes, G10 composite has a high level of electrical insulation, which means that it does not conduct electricity well. This makes it a good choice for use in electrical applications, such as in the production of circuit boards and other electrical components.
Is G10 composite easy to machine?
G10 composite can be machined, but it is not as easy to machine as some other materials, such as metals. It is important to use the correct tools and techniques when machining G10 composite to avoid damaging the material.
