Briefly describe the characteristics and applications of fiberglass  chopped strand mat

  Fiberglass chopped strand mat is made of fiberglass raw silk cake (untwisted roving is also acceptable), cut into 50mm long raw silk by a cutter, and settles randomly and disorderly on the stainless steel mesh belt to form a mat. The fiberglass chopped strands are bonded together by spraying binder + or water spraying and removing the powdery binder, and then dried at high temperature and cooled to shape. Form emulsion chopped strand mat or powder chopped strand mat.

  Various characteristics of fiberglass mat

  Fiberglass mat is a high-grade felt with insulation, heat insulation, fire prevention, noise reduction, air purification and other properties made by cutting fiberglass into certain lengths, and then going through processes such as filament separation, cashmere forming, and acupuncture.

  1. Good thermal insulation: According to physical principles, the thermal conductivity of gas is small, and there are many air pockets in the excellent thermal insulation material. fiberglass needle-punched cotton has countless fine gases, and the fibers are arranged irregularly. It is an excellent thermal insulation material with a thermal conductivity of 0.2-0.040kcal/mhr.

  2. No burning: The main component of fiberglass  is silicide (accounting for more than 50%), which is non-combustible, non-deformable, non-brittle, and can withstand high temperatures up to 7000C;

  3. Good sound absorption rate: When sound waves invade fiberglass  cotton, a large amount of energy will be absorbed due to friction with fibers and air pockets of different sizes. Generally speaking, the sound absorption rate is as high as 90%, which is a good talent to prevent noise interference;

  4. High insulation: fiberglass  can withstand high temperature, has good mechanical properties, and has high chemical stability. It is a good insulating material;

  5. High corrosion resistance: fiberglass  is not afraid of strong acid and alkali, and will not reduce its functional properties for a long time;

  6. Good recovery: the fiberglass  contains countless fixed air pockets, and the recovery is excellent. Not afraid of any impact and vibration, the tensile strength is above 1.0kg.

  7. Low moisture absorption rate: The moisture absorption rate is usually close to zero.

  8. Light and soft: Compared with other insulation materials, fiberglass needle felt is light and soft. If it is installed on a machine, its weight and vibration load can be reduced.

  9. Simple construction: the size can be cut according to the customer.

Application of fiberglass chopped strand mat in Various Fields

  Chopped strand mat has uniform distribution, isotropy, fast resin penetration and consistent speed, and good film coating performance. Due to the superior performance of fiberglass chopped strand mat, it is especially suitable for the production of hand lay-up or compression molding FRP products.

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

Automotive: Structures and bumpers, from cars to heavy commercial construction equipment, the beds of trucks, and even armored vehicles. All of these parts are constantly exposed to extreme weather and are subject to constant wear and tear.

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

  Steel structure: Bridge decking reinforcement is replaced with fiberglass, which has the strength of steel while resisting corrosion. For suspension bridges with very wide spans, if they are made of steel, they will collapse under their own weight. It has been proven that fiberglass railings are stronger than their steel counterparts. From hydropower transmission towers, to street light poles, street manhole covers are widely used due to their strength, light weight and durability.

  According to different uses and processes, the amount and method of use of chopped strand mat are also different, and the thickness of the layer is also different according to the required process of the product!
