What are the applications of fiberglass cloth?

yinuoqianjin supply professional and honest service.

Different fiber cloths have different applications. At present, the market is mainly glass fiber cloth, carbon fiber cloth, polymer fiber cloth, etc., but the most widely used glass fiber cloth is because of its suitable price and better performance. Fiberglass cloth is generally used for reinforcement materials, filter materials, reinforced matrix materials, heat preservation, sound insulation materials, and so on. To this end, the following will focus on the market application of glass fiber cloth.

Listed below are the main uses of fiberglass mesh in the construction field.

1. External wall insulation system

Spread the first layer of plaster on the insulation board of the outer wall and then spread the fiberglass mesh cloth as a reinforcement layer, and then spread the cover layer. This avoids surface cracks that may be caused by external temperature fluctuations, mortar shrinkage, and movement of the insulation board. The glass fiber mesh ensures the stability of the external wall insulation system.

2. Waterproof material

The glass fiber mesh cloth can be used as a waterproof material for the new and old layers after being asphalted. Similarly, the organic resin can also be used to coat glass fiber mesh with asphalt, tar or cement to form the roof waterproof layer of new and old houses. Glass fiber mesh is also used to reinforce cast-in-place epoxy asphalt or acrylic waterproof membranes. Irregular surfaces or slopes can be reinforced with special mesh fabric made of glass fiber bulked yarn. This kind of mesh can effectively absorb the waterproof material, thereby preventing the waterproof material from dripping and helping it to be evenly distributed.

A typical application of glass fiber cloth:

1. Smokescreen, fire curtain, fireproof clothing, fire blanket, welding blanket, fire and smoke curtain, fire blanket.

2. The cable is fireproof.

3. Removable insulation jacket and insulation pad.

4. The construction and repair of ship frames in the shipbuilding industry.

5. The petrochemical enterprises shall heat and insulate metal structures and other places where welding is required.

6. Aerospace, chemical, petroleum, energy, metallurgy, large-scale power generation equipment, electrical insulation, cement, machinery, construction, and other fields.

7. Manufacture of copper-clad laminates as the basic material of printed circuit boards.

8. Used for high-temperature atmospheric dust removal and recovery of valuable industrial dust. For example cement, carbon black, steel, metallurgy, lime kiln, thermal power generation, and coal burning industries.

9. The soft connection of the power unit, the boiler, and the chimney, and the heat insulation of the engine compartment.

10. It is used for pipeline compensation of exhaust, ventilation, ventilation, smoke, and dust, waste gas treatment, and other systems.

12. Boiler insulation.

13. Pipe bandaging.

14. Other fire insulation systems.

Do you have a project in mind but have no idea where to start?  Let us help you.  One of the first things you will want to do is decide what kind of fiberglass you want to use.  Do you need to build up thickness fast?  Are you concerned about strength? Do you have tight corners you are working with?  Let us break things down a bit to help you decide if fiberglass cloth is right for your project or if you are needing chopped strand mat. Keep in mind that you can actually use both together to achieve your desired outcome. Below is an overview.

Fiberglass Cloth

(Plain weave fiberglass cloth)

Fiberglass Cloth is a woven fabric. Plain, 4 harness satin and 8 harness satin are the weave styles we carry. The 4, 6 and 10 ounce plain weave fabrics are the most commonly used. In this simple plain weave pattern, warp and fill yarns are interlaced over and under each other in alternating fashion. The plain weave is the easiest to handle since it does not unravel as much as the other weaves when cut.

In the four-harness satin weave pattern there is a three by one interfacing where a filling yarn floats over three warp yarns and under one.

The eight harness satin is similar to the four harness satin except that one filling yarn floats over seven warp yarns and under one. The satin weaves are slightly stronger and more pliable than the plain weave and are easier to conform to curved surfaces. They are more difficult to handle than the plain weave, though. Use fiberglass cloth when you are looking to create a strong, light weight product.

Chopped Strand Mat

Chopped Strand Mat (also known as fiberglass mat) has short strands of fibers held together with a resin binder. The fibers are randomly oriented. Mat is only compatible with polyester and vinyl ester resin. When resin is added to the mat, the binder dissolves and the fibers can be moved around. It is easier to conform mat to tight curves and corners than it is with weaved fabric. The reason chopped strand mat is not compatible with epoxy resin is because the binder holding the fibers together needs styrene to properly dissolve.  Polyester and vinyl ester resins have styrene in them. (There are some places that sell chopped strand mat that is compatible with epoxy but it is hard to come by and much more expensive). Chopped strand mat is the least expensive fiberglass and is often used in mold construction or projects where thickness is needed. Mat is often used as the first layer (before the gelcoat) in a laminate to prevent print through. Print through is when the fabric weave texture shows through the resin. Chopped Strand mat does not have much strength. If you need strength you should choose a woven cloth or you could mix the two. Mat can be used between layers of woven fabric to help build thickness quickly and aid in all layers bonding well together.
