G-10 material Wikipedia

Created by the stacking of multiple glass cloth layers. Then by heat and pressure, it is compressed into the shape you are looking for. As with most fiberglass, this stacking provides amazing strength and durability. This is a very popular and strong material used in many industries in custom fabrication for good reason.

The differences in thread count in the warp and fill directions result in different physical properties in these directions. G10 material has insulating properties that are beneficial for electrical applications. G10 also meets the standards set by the National Electrical Manufacturers Association. The versatility of G10 FR4 allows it to be used through different electronic purposes like mechanical lines. G10 is very strong and it shows through different properties like its stability, as shrinkage is under 1%.

It displays amazing properties and offers lifetime use without maintenance. Working with G10 material is working with some of the strongest materials on the market. The insulating properties, strength, fire and electrical insulation and moisture resistances lend itself to a variety of applications. G-10 FR-4 is a thermosetting industrial fibre glass composite laminate consisting of a continuous filament glass cloth material with an epoxy resin binder. This product, first introduced in the 1950’s, has characteristics of high strength, low moisture absorption, excellent electrical properties and chemical resistance. These properties are maintained not only at room temperature but also under humid or moist conditions.

G-10 resin chemistry is readily adaptable

G-10 tube is vacuum-tight to air and nitrogen gas and vacuum-tight epoxy joints to stainless steel are possible. (Ref. 2) It is used to make low heat leak necks of dewars. In terms of vacuum compatibility, G-10 compares reasonably well with other plastics. The glass cloth gives G-10 a thermal contraction which is well matched to that of stainless steel. Epoxy resins are widely used in electronic applications because they are virtually impervious to moisture. As a thermoset material, glass epoxy has outstanding mechanical and electric strength as well as good dielectric properties.

Hazards from G10 are typically from cutting and grinding the material, the dust from glass and epoxy leads to an increase of long term respiratory illnesses. Whenever cut or grinded, wearing a respirator or other similar face protection equipment is a must. Once G10 is dried it is perfectly fine to be around, but if it is burned or melted it will produce toxic fumes. Contact us about fulfilling your material needs and to get a quote.

G-10, like FR-4, FR-5, and G-11 are interesting to designers because they are one of the few composite materials that have an established set of performance requirements. This makes them easier to work with in the initial design phase where many composite materials require expertise to judge their potential performance characteristics. The NEMA Standard provides generic category recognition of grades based on their construction, reinforcement, and resin. Typical properties and performance requirements for each category are defined and published along with standard dimensional tolerances for standard forms of the product. G-10 is the toughest of the glass fiber resin laminates and therefore the most commonly used. And unlike other G-10 available in the market, UltreX™ G-10 is produced in the USA.

G10 comes in flat sheets and it is incredibly tough, in comparison to other glass fiber resin laminates. Look at G10 Material if you need something very electrically stable and sound. This https://1investing.in/ material conducts almost no electricity which lends itself perfectly to the circuit board industry. And, it has properties that keep the coefficient of thermal expansion to a minimum.


With these outstanding characteristics, it is easy to understand why G-10 FR-4 is such a versatile material and is used in a wide variety of applications. g 10 material G-10 FR-4 Rod is commonly turned, and ground from sheet stock. You can special order Mil Spec grade rolled and molded rod on a custom order basis.

  • The insulating properties, strength, fire and electrical insulation and moisture resistances lend itself to a variety of applications.
  • G10/FR-4 Glass Epoxy is also used for mechanical applications when outstanding strength, stiffness, and excellent creep resistance are required.
  • The cryogenic material properties of NEMA G-10 and G-10FRP and G-11 grades can vary widely while still meeting the NEMA specification.
  • Another variation of G10 fiberglass sheet is G10 CR laminate used in cryogenic applications.

Due to G-10’s high level of durability, it is one of the most widely used materials in the gun and knife industry. Its sleek appearance and durable qualities make it far more favorable compared to various other materials. G-10 does not rust, oxidize, become brittle, or become softer overtime. Epoxy resins are a good choice of thermosets for fabricated components for many electrical and mechanical applications. You may have heard of G10 and that it has something to do with manufacturing electrical boards.

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. 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. Locating material property data at cryogenic temperatures is, of course, a key to utilizing G-10CR and G-11CR in cryogenic design. The National Institute of Standards and Technology maintains an onlinedatabasefor material properties of materials common to cryogenic applications.

Low Absorption

The cryogenic material properties of NEMA G-10 and G-10FRP and G-11 grades can vary widely while still meeting the NEMA specification. 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.

Food-Safe Materials

It is manufactured in flat sheets, most often a few millimeters thick. The G-10, G-11, and G-10-FR4 (fire retardant version of G-10) grades can all meet NEMA specifications while varying in fabric style, epoxy formulation, and manufacturing procedures. This leads to a variability in low temperature mechanical and thermal properties that is not always acceptable in cryogenic design applications.

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. FR-4 and G-10 are the most versatile all-around of the laminate grades and are made by impregnating an epoxy resin binder into continuous glass woven fabric. G10/FR4 has extremely high mechanical strength, good dielectric loss properties, and good electric strength properties, both wet and dry. G10/FR4 are widely used in the electronics field – primarily because water absorption is virtually nil, rendering it an excellent insulator. Because G10 has little water absorption using it in and around boats is a great option.
