Fiberglass chopped strand mat is an important nonwoven reinforcement material, which is main material of fiberglass hand layup process. The chopped fiberglass strand or roving is non-directional and even distributed, then combined with powder binder or emulsion binder.
The chopped mats are widely used in various FRP applications, such as, tanks, corrugated sheet, automobile parts etc., which has good wet out properties and high tensile strength. The production line takes the chopped fiberglass strand or roving as mat, so it has the characteristics of fine uniformity, high auto-control, lower energy consumption, easy operation and maintenance.
The production lines can manufacture powder, emulsion, non-soda and neutral-soda chopped mats. The line design width of 2.6 meters, 3.6 meters, the capacity is 5,000 tons / year and 8,000 tons/year respectively.
In Mat Production process, assembled roving is chopped to a specified length by a roll with blades and an elastomeric roll, and then falls on the transportation carpet randomly. Then the chopped strands are bonded together by either an emulsion binder or a powder binder. The chopped strand mat will be rolled in a certain width and length after heating.
E-glass chopped strand mat powder is made of e-glass chopped roving, the random non-directional spread evenly, then bonded together with powder binder made continuous mat.
Applicable resin and products
It’s suitable for reinforced unsaturated polyester resins, vinyl resins, epoxy resins.
Chopped strand mat is the largest amount in hand lay-up process, and it ‘s also can be used for winding, molding, continuous system boards and other technology. The main end products are all kinds of boards, boats, bathroom equipment, automotive parts and cooling towers and so on.
There is a uniform unit area weight, which ensure the fiberglass content and stable the mechanical properties.
The binder distributed evenly that ensure good adhesion, less fuzz, while the volume of small diameter mat.
The mat has excellent flexibility as its struction. They have some other characters when operation that is good molding and it without rebound in small angle.
Resin impregnated fast and consistent speed, easy to remove air bubbles, reduce resin consumption and production costs, while improving productivity and mechanical properties of the final product.
The product has high strength in dry and wet and good transparency.
It’s applicable to reinforced unsaturated polyester resin, vinyl resin, an epoxy resin and the like. Chopped strand mat, the largest amount in hand lay-up process, but also can be used for winding, molding, continuous system boards and other technology. The main end products are all kinds of boards, boats, bathroom equipment, automotive parts and cooling towers.
Fiberglass pool is directly pre-fabricated from the factory, and ready to install. In fact, it just approved by the Council after four days you can swim. In contrast, the concrete pool can take months to complete, during this period, your backyard will look a mess!
Fiberglass pool has a smooth clean finish gel coat, not rough. No sharp edges or rough surfaces. Compared with this, a number of pebble pool is very rough they can hurt your skin.
In the gel coat finish not only looks great, but also it is very easy to take care. The surface is smooth and non-porous, so that it is easy to clear and stain.
Low chemical usage
Nobody likes to swim in the chemical cocktail, but some pools require constant monitoring and expensive chemicals. Not so, glass fiber FRP tank, so there is no surface chemically inert in the pool surface can change the water chemistry. Thus, it has very low use of chemicals and run your pool considerable cost savings.
The shell thickness of Fiberglass pool exceeds the Australian standards. High tensile strength glass fiber will allow the pool shell without cracking to accommodate crustal movement. No wonder fiberglass aircraft manufacturers are using to build the plane!
The focus for this heavier truck component is again weight savings, with a reported 400 kg saved compared to a steel component. IFC says this weight savings can be used in load or converted to improve fuel economy. The CO2 emissions also decrease and the vehicle benefits from the finer response and reduced tire noise.

Why should you start using FRP cross arms in your next transmission project?
There are 6 reasons to explain this.
As mentioned above, accelerated aging tests performed by an independent laboratory confirmed that two component polyurethane composite cross arms have an expected life span of over 75 years. This is significantly better than the expected life span of wood cross arms and galvanized steel (with no additional corrosion intervention once the galvanized coating is gone), which is about 35 years in most urban environments.Official website:http://www.zccyfiberglass.com
The glass fibers are transferred from the conveyor belt of the forming section to another conveyor belt for the binder application. The forming belt will remain clean and dry everytime. Binding with powder is composed by 2(two) powder-binder-applicators, and a series of sprays of demineralized (distilled) water.
Both sides of the mat, the upper and the lower-one, are lightly sprayed with distilled water, that operation is necessary or a better adhesion of the binder. The special powder-applicators warrant an optimal distributing .
Between the two applicators a vibrator is applied providing that the powder is also passing to the lower side of the mat.
Binding with Emulsion
The curtain system used warrants a perfect distribution of the binder. The excess of binder will be recovered by a special sucking system.
This system pulls the air through the fiberglass chopped strand mat and a part of the binder will be taken off. By that mater the binder will be distributed uniformly and the excess of binder eliminated.
Obviously the binder will be re-employed after special filtering which separates the air and the dirt.
The binder is stored in containers in the mixing room and conveyed at low pressure by a pipeline to a small tank near the mat-plant.
A special device maintain the level of the tank constant. Also the recovered binder will be conveyed to the tank. A pumping system conveys the binder from that tank to the curtain distribution system.
