What is the difference between fiberglass cloth and fiberglass mat?

Fiberglass cloth and fiberglass mat sound like only one word difference, and the raw materials are also the same. So what is the difference between fiberglass cloth and fiberglass mat in terms of technology and use?

Glass fiber mat is chopped strands of glass fiber strands, which are randomly and evenly distributed into continuous glass fiber paper sheets by the papermaking method, and are bonded with emulsion. Its main performance and characteristics: chemical resistance, fire resistance, flame retardant, waterproof, aging resistance, weather resistance, insulation and other characteristics. It is widely used as fiberglass base cloth, anti-corrosion, heat preservation, fire-retardant, waterproof material, epoxy clad copper board and electrical insulation products. The medium-alkali glass fiber mat is suitable for continuous machine operation or hand lay-up to make various glass fiber reinforced plastic products (FRP), plates, pipes, tanks, tanks, cruise ships, bathtubs and other products. The alkali-free glass fiber felt is used for epoxy clad copper board and electrical insulation products.

The glass fiber surface mat is used as a gel coat layer reinforcement mat. It is an all-directionally distributed fiber. Its softness makes it suitable for angular, irregular shapes and complex curved surfaces. It is suitable for a variety of composite material processes and can be compared with EP , VE, UP and PU resins dissolve quickly, forming a resin-rich layer between the fiber gaps, giving a smooth and flat surface, effectively avoiding pits on the surface after forming and fiber lines hidden in the fibers. It also highlights the strengthening of interlayer shear strength, surface toughness and excellent chemical and corrosion resistance.

Fiberglass cloth is a kind of inorganic non-metallic material with excellent performance. It has a wide variety of advantages. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is several microns to more than 20 meters, which is equivalent to a hair strand. Each fiber strand is composed of hundreds or even thousands of monofilaments. Glass fiber is generally used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy. Suitable for high temperature environment of 500℃-1000℃. Not only has excellent high temperature resistance, but also has the advantages of low bulk density, low thermal conductivity, thermal shock resistance, chemical corrosion resistance, and easy construction.

In addition, glass fiber cloth is an inorganic fiber board made of basalt as the primary raw material through a series of technical processes such as high-temperature melting, fiberization treatment, and post-processing of commodities. It has excellent heat insulation, sound absorption, fire prevention, and light weight, which is attributed to the new building materials.
