What is fiberglass

Fiberglass is an inorganic non-metallic material with excellent performance. It is made of ore as raw material through high-temperature melting, wire drawing, winding, weaving and other processes. Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. The diameter of its monofilament is several microns to twenty microns, which is equivalent to 1/20-1/5 of a hair. Each bundle of fiber strands consists of hundreds or even thousands of monofilaments. It has good insulation, heat resistance, corrosion resistance and high mechanical strength, but the disadvantage is that it is brittle and has poor wear resistance. Fibersglass is commonly used as reinforcements in composite materials.

Material Properties

  • Melting point: 500~750℃.
  • Boiling point: about 1000 ℃.
  • Density: 2.4~2.76 g/cm3.

Material classification

According to the length, fiberglass can be divided into the continuous fiber, long fiber, and short fiber; according to the glass composition, it can be divided into alkali-free (E-fiberglass), medium alkali (C-fiberglass), high alkali (A-fiberglass)), chemical resistance (E-CR), high strength (S-fiberglass), high elastic modulus (M-fiberglass) and alkali resistance (AR-fiberglass).
