How is the G10 made?

G10 is a blend of epoxy resin, fiber and hardener. This is then coated on glass fabric to form prepreg, a glass fabric impregnated with epoxy resin. The fabric can then be cut and pressed together to create materials with a variety of unique properties.

Material preparation: The first step in making G10 is to prepare the materials. The main ingredients include epoxy resin and fiberglass cloth. Epoxy resin is usually a mixture of two liquid components, one part epoxy resin and the other part a hardener. Fiberglass cloth is fiber cloth pre-coated with a layer of epoxy resin.

Laminated Fabric: Fiberglass cloth pre-coated with epoxy resin is layered together to create a multi-layered structure. Each layer may be oriented differently to enhance the overall mechanical properties of the G10.

Curing: Place layers of fiberglass cloth in the mold and allow to cure. During the curing process, the epoxy resin will react chemically and the hardener will gradually solidify it into a hard material. This step usually requires a certain temperature and time.

Hot pressing: Put the material in the mold into a heating press for hot pressing. This helps further solidify the material, increase density, and ensure an even distribution of fibers within the material.

Cutting and Processing: The cured material is cut and processed into the desired shape and size to meet the requirements of the specific application. This may include cutting into sheets, processing into insulating gaskets, or other specific shapes.

G10 operating temperature range

Normal temperature applications: G10 can be widely used in normal temperature environments (room temperature, usually 20-25 degrees Celsius), including circuit board manufacturing, insulating gaskets, structural supports, etc.

Medium temperature applications: G10 still maintains good performance in the medium temperature range (such as 50-100 degrees Celsius), and is suitable for some applications that require higher temperature stability.

High temperature applications: In some high temperature environments (over 100 degrees Celsius), G10 may still have sufficient stability, but the specific temperature limit depends on the specific product specifications.

What are the advantages of G10?

Excellent electrical insulation properties: G10 has excellent electrical insulation properties, making it ideal for electrical and electronic applications. It can effectively isolate circuits and prevent current leakage and breakdown.

High Mechanical Strength: Due to the reinforcement of glass fibers, G10 has excellent mechanical strength and stiffness. This makes it useful in applications requiring structural support, rigidity and wear resistance.

Chemical corrosion resistance: G10 has good chemical corrosion resistance and can resist the erosion of some chemical substances, making it more stable in corrosive environments.

High temperature resistance: G10 shows excellent thermal stability within a certain temperature range and can work stably in medium and high temperature environments, generally reaching more than 150 degrees Celsius.

Dimensional stability: G10's size and shape are relatively stable when temperature and humidity change, making it very useful in some applications that require high dimensional accuracy.

Good workability: G10 is relatively easy to process and process into various shapes, which can meet the needs of different applications.

Lightweight: Despite its high mechanical strength, the G10 is still relatively lightweight, which helps keep the overall device weight down.

Flame retardancy: G10 generally has good flame retardant properties, is able to self-extinguish in case of fire, and meets some flame retardant standards.

Disadvantages of using G10

Relative brittleness: Although G10 has good mechanical strength, it may exhibit a certain brittleness relative to some metals and other composite materials and is prone to cracking when impacted or bent.

Wear during machining: The machining of G10 may cause rapid tool

G10 has a wide range of applications including:

Electrical Accessories – G10 is commonly used in electrical accessories such as wiring due to its non-sparking, non-conductive properties.

Firearms Accessories – G10 is often used in firearms accessories such as stocks and knife handles due to its durability and strength.

Marine - G10 is commonly used in marine equipment such as hulls, covers, canopies, etc. due to its corrosion resistance.

Aircraft – Due to its non-sparking, non-conductive properties, G10 is often used in aircraft equipment such as panels, instruments and wiring.

Power Generation – G10 is commonly used in power generation, transformers and distribution equipment because it does not absorb water and has excellent high voltage insulation and isolation properties.

Is the material of G10 good?

Yes, G10 is a very strong and durable material suitable for a variety of applications. Due to its non-sparking, non-conductive properties, G10 is particularly suitable for applications where sparks are present and where lightweight and high strength are required.
