Dymriton Conductive Veils: Safeguard Against Static Electricity & Optimize Composite Structures

Surfacing veil is a very thin sheet material formed from either synthetic polyester fiber of random lengths or very fine C-glass fibers. Exotic veils, such as carbon fiber veil, are sometimes used where specialized properties are needed. The veil is used to place a thin (10mils per ply), even, highly resin-rich surface onto FRP equipment in areas that will be in contact with a corrosive environment.

“There are many kinds of Dymriton surfacing veil series: polyester fiber surface veil, polypropylene clear fiber surface veil, glass fiber surface veil, carbon fiber surface veil, conductive veil, with needling and wet manufacturing processes.”

At the same time, we can sew the surface veil with glass fiber reinforced materials, PP resin layer materials, and other materials through polyester yarn or acupuncture to form a special combination mat, which greatly reduces the labor force of manual laying, covers the surface texture of FRP finished products, improves the surface finish, saves working time and reduces the cost. It has been welcomed by the majority of users.

Surface veil (except carbon fiber surface veil) needs to achieve electrical conductivity through (polyester fiber, polypropylene fiber, aramid fiber, graphite fiber, etc.) is added with very fine metal conductive fiber. It is a thin veil with a uniform surface processed by needling non-woven. After it is made into finished products through different FRP manufacturing processes, RTM, L-RTM, vacuum diversion, hand paste, etc. with other materials, its surface has excellent conductive properties, which can be used in some applications Performance on industry products. It can dissipate static electricity or ground composite parts for the electrostatic arc.

We all know that static electricity is the accumulation of excess charge in materials with poor conductivity. The excess charge will find the conductor and ground along the path to neutralize the charge accumulation, resulting in a spark or arc. In industrial applications, this accumulation of static electricity can lead to catastrophic events.

The friction motor system that generates static electricity is that the two materials only need to contact and then separate from each other to exchange some kind of electron-charge polarity, so as to form static electricity. When the liquid flows through a closed pipe system, there is significant contact between the liquid and the pipe wall. The resulting friction will cause a lot of static electricity.

For industrial equipment designers, whether for safety reasons or damage to infrastructure and goods. In the presence of flammable liquid (such as petroleum distillate), static electricity is allowed to generate electric arc, and many records show that it will cause harm to personnel and equipment. In order to control this phenomenon, corresponding measures are designed in the process equipment through which the liquid flows.

The advantage of conductive surface veil is the conductivity of the material, which is used for the grounding of composite structure products to minimize the accumulation of static electricity. Static dissipation is particularly important in composite tanks and pipelines dealing with explosive or flammable liquids and gases.

Dymriton’s conductive veils and mats use the electrically conductive nature of carbon, metal coated carbon and metallic fibres to achieve a range of levels of surface and bulk conductivity in composite components.

There are usually two kinds of conductive surface veils: polyester fiber conductive veil and polypropylene fiber conductive veil. A certain amount of metal conductive fiber is added. The gram weight is 60g, 80g, 100g and 120g. The conventional width is 1m and the maximum width is 2.6m. The width of other specifications can be customized.

Conductive surface veil of other graphite fiber, aramid fiber and other materials can be produced. If you have special needs, please contact us.
