Production process and application of glass fiber mat

一、Introduction to the production process of glass fiber mat

  The production process of Chopped strand mat can be divided into four processes: glass fiber forming process, binder feeding process, glass fiber bonding process and glass fiber winding process.

1. Glass fiber forming process
Fiberglass creel: placed in an air-conditioned room, humidity controlled at 82-90%, and plied rovings are placed on the creel according to the set specifications and quantities.
Chopped cutting unit: Each chopped machine is equipped with an independently controlled variable frequency motor, which can cut several bundles of stranded rovings into equal lengths of about 50mm.
Scattering: It is controlled independently with the chopper, so that the fibers are randomly and evenly spread on the mesh belt.

2. Binder feeding process
The so-called Emulsion fiberglass chopped strand mat and Powder fiberglass chopped strand mat are distinguished by this process.
When producing powdered fiberglass mat, the spraying equipment sprays the water, which is a necessary step for the powdered adhesive to be better attached, and the dusting equipment applies the powdered adhesive.
When producing emulsion glass fiber, the spray equipment sprays latex diluted with water, and the dusting equipment does not work.

3. Glass fiber bonding process
Use an oven to dry the excess water to bond the glass fiber to the glass fiber.

4. Glass fiber winding process
Cool the fiberglass mat, trim the burrs on both sides and cut it to the desired size, and automatically wind it up.


  二、 Factors affecting the strength of glass fiber mat

  Is Glass fibre fabric the same as glass?

  Woven roving fabric is made of glass into very thin glass filaments, and the glass filaments at this time have good flexibility. Spin the glass fiber into yarn purchase, and then use the loom to weave fiberglass cloth. Since the glass filament is very thin and the surface area per unit mass is very large, the temperature resistance performance is reduced. It's like melting a thin copper wire with a candle.


  But glass is not a burning body. The burning that we can see is actually the resin material coated on the surface of the glass fiber cloth to improve the performance of the glass fiber cloth, or the attached impurities. After pure glass fiber cloth and some high temperature resistant coatings are applied, it can be used to make products such as refractory clothing, refractory gloves, and refractory blankets. However, if it is in direct contact with the skin, the broken fibers will irritate the skin and it will be very itchy.

  What are the factors that affect the strength of glass fiber chopped strand mat

1.Adhesive, the manufacturer will formulate the production requirements of chopped strand felt according to the customer's use process.
2.Some people may not understand that any product will have a shelf life, and glass fibre felt is no exception. Glass fiber chopped strand mat is made of adhesive. After a long time, the adhesive will age, and the moisture in the air will erode the mat and affect the strength of the mat.
3.The direct factor that affects the strength of the felt is the cutting strength during production. The greater the cutting strength, the greater the impact on the strength of the felt, and the easier it is to tear the felt.


  三、Application of glass fiber mat in various fields

  Glass fiber chopped strand mat is a kind of main fiberglass reinforced. Chopped strand mat has uniform distribution, isotropy, fast and consistent resin penetration, and good lamination performance. Due to the superior properties of glass fibre matt, it is especially suitable for the production of hand lay-up or moulded FRP products. So, let's follow Hongxiang Xiaobian now to see what the unexpected finished products of the small glass fiber chopped strand mat are.

  Aircraft: With a high strength-to-weight ratio, fibet glass is ideal for aircraft fuselages, propellers and nose cones for high-performance jets.

  Automotive: Structures and bumpers, from automobiles to heavy commercial construction equipment, truck beds, and even armored vehicles. All of these parts are often exposed to extreme weather and are often subject to wear and tear.

  Boats: 95% of boats are made of fiberglass due to its ability to withstand cold and heat. Its resistance to corrosion, salt water and atmospheric pollution.

  Steel structure: The bridge deck reinforcement is replaced by fiberglass, which has the strength of steel while resisting corrosion. Suspension bridges with wide spans, if made of steel, would collapse under their own weight. Fiberglass road rails have been shown to be stronger than their steel counterparts. Water and electricity transmission towers, to street light poles, and street manhole covers are widely used due to their strength, light weight and durability.
