G-10 material Wikipedia

There are so many materials out there and it is impossible to know them all. The material must have custom fabrication and it is not an injection molding type of material. It is quite difficult to machine and must use specialized cutters due to the strength of the material.

  • It is quite difficult to machine and must use specialized cutters due to the strength of the material.
  • These properties are maintained not only at room temperature but also under humid or moist conditions.
  • This makes it the perfect material to be used for electrical circuit boards.

And, it has properties that keep the coefficient of thermal expansion to a minimum. This is why you see G10 material being used so often in circuit boards. If material that had all the circuit board parts attached expanded greatly it would cause harm to the computers and other components. As mentioned previously, it has great electrical properties, this comes from its high insulating factors, which means that electrical current cannot flow through it. This makes it the perfect material to be used for electrical circuit boards.

What is Garolite? Your guide to G10 Material – Its Properties & Applications

G-10 is favored for its high strength, low moisture absorption, and high level of electrical insulation and chemical resistance. 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. G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. 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. It is manufactured in flat sheets, most often a few millimeters thick.

It has great fire and electrical insulation properties and is resistant to oil and moisture, which helps make it the perfect match for the engine room in ships. This material has a super high strength that stops it from bending or breaking under load. It doesn’t absorb moisture even when exposed over time and oil doesn’t bother the G10 material. These are some extremely strong and desirable properties for many applications.

Garolite generally comes in sheets, and these sheets are made up of resin along with fiberglass, and it is the fiberglass that provides the rigidity for the material. Garolie can actually be machines so that it can be “insert molded” into a product, and it can provide some strength due to the properties of the fiberglass. Garolite is a compositematerial and brand name for G10 – FR4, which is developed by curing epoxy and fiberglass under high pressure to create a thermoset glass-epoxy laminate material. It is very stable over temperature, absorbs a low amount of moisture and possesses a good strength to weight ratio. You may have heard of G10 and that it has something to do with manufacturing electrical boards.

The material is similar to cutting sheet metal and offers very little heat expansion so getting the blade a bit hot will not affect the cut at all. Look at G10 Material https://1investing.in/ if you need something very electrically stable and sound. This material conducts almost no electricity which lends itself perfectly to the circuit board industry.


G10 does break down in UV light, so if it’s a component that is exposed to the sun, not a good idea. However, all those other places on a boat that needs backing plates and such, you have found the best product for such an application in G10. The only way to use G10 for parts is to machine g 10 material it, it cannot beinjection moulded. It typically comes in bar, sheet and rod shapes, and a part’s size may depend on the stock size of the material that is available at that present moment. If you should have any questions regarding G10, and still asking yourself “what is G10?

But, this marvelous material has a life that can extend far beyond those circuit boards. Due to the fact that it absorbs very little water, it has many applications in the marine field. Here it is used in the engine compartment among others because of its electrical insulation properties as well as its water and oil resistance. It is also used to patch holes in boats as it is very strong and can also be painted to match the colour of the boat so the repair can go undetected. It generally has a smooth, matte finish that needs a coat of lacquer to retain a shine.

Garolite G10 Properties

Therefore similar materials like FR-4 containing flame retardant additives have replaced G-10 in many applications. Hazards can result from cutting or grinding the material, as glass and epoxy dust are well known to contribute to respiratory disorders and increase the risk of developing lung cancer. For any work of this kind, the work space should be appropriately ventilated and masks or respirators must be worn.

Because G10 has little water absorption using it in and around boats is a great option. It is very similar to the popular starboard because G10’s epoxy it bonds well with other epoxies. G10 is non-corrosive as well and makes great back plates for high load applications due to its strength. It is the perfect material for Engine room bulkhead and holding engine mounting brackets.

G10 material is a high-pressure fiberglass laminate that can be used in things other than Circuit boards. It is created by stacking multiple layers of glass cloth into a soaking epoxy resin. G10 material can be used in a variety of applications such as knife handles, boating applications, printed circuit boards, Insulators, jigs and fixtures, and other components.

What is Garolite Used for?

However, G10 can be fabricated, machined and assembled with the correct equipment and the final product is amazing. We connect engineers, product designers and procurement teams with the best materials and suppliers for their job. Epoxy resin is flammable and, once set on fire, will burn violently, giving off poisonous gases.

It is used in circuit board manufacturing because it has very desirable properties, being an excellent insulator and having a very low coefficient of thermal expansion. This means that it meets UL 94V-0 standards for flame retardance and is a material that is used in the Aerospace, Marine and Medical industries. This leads to a higher cost for the material, pushing more towards a “premium” price tag with a longer than normal lead time in comparison to other metals or plastics. G-10 is the toughest of the glass fiber resin laminates and therefore the most commonly used. Which is used in most boating applications, however, it’s not as widely used. This is because very few people are aware that G10 is far less costly and has virtually the same properties.
