Explain the specific functions of Glass Mat

Glass Mat is an inorganic non-metallic material with excellent performance. There are many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. However, its disadvantages are brittleness and poor wear resistance. It is made of six kinds of ores such as pyrophyllite, quartz sand, limestone, dolomite, ponite, and boronite as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its single filament is several From one micron to more than twenty microns, which is equivalent to 1/20-1/5 of a hair. Each fiber strand is composed of hundreds or even thousands of single filaments.

Fiber Glass is often used as reinforcing materials in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other fields of the national economy. Glass Mat itself has the characteristics of good insulation, high temperature resistance and corrosion resistance, and it is also used by 3D printing technology.
When Fiber Glass is used as a reinforcing material for reinforced plastics, its biggest feature is its high tensile strength. The tensile strength is 6.3~6.9g/d in the standard state and 5.4~5.8g/d in the wet state. It has good heat resistance and has no effect on the strength when the temperature reaches 300℃. It has excellent electrical insulation properties and is a good electrical insulation material. It is also used in thermal insulation materials and fireproof shielding materials.
Generally only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid. Fiber Glass has higher temperature resistance than organic fibers, is non-flammable, corrosion-resistant, has good heat and sound insulation, high tensile strength and good electrical insulation. But it is brittle and has poor wear resistance. According to the shape and length, Fiber Glass can be divided into continuous fiber, fixed length fiber and glass wool; according to the glass composition, it can be divided into alkali-free, chemical-resistant, high-alkali, medium-alkali, high-strength, high elastic modulus and alkali-resistant (Alkali-resistant) Glass Mat, etc.
