Our glass modelsArtificial & Mineral Material

Glass is the most used material in the world as an inorganic fiber. It has the advantage of being economical and has good thermal and mechanical performance. Its main component is silica, in greater or lesser proportion depending on the desired use. These include: E glass = general use D glass = reinforced dielectric properties AR glass = resistant to alkalis S or R glass = reinforced mechanical properties

E-glass being the most used version. This material has a crystalline structure which gives it its rigidity, and is produced in the form of an extremely fine filament of 3 to 13 µm (we then speak of silionne. The composition is heated, becomes viscous at 800°C then liquid and vitrifies at 1500° C. This molten glass passes through a spinneret where it is transformed into filaments which are stretched at high speed. These filaments are then wound on drums) or in the form of fiber (we then speak of veranne). filaments are blown by a jet of air, which breaks the filaments into irregular sections and gives volume to the fibres).

Used for technical applications, in particular for its non-fire properties, its insulating power and its chemical inertness. These include fire-retardant or sound-insulating fabrics, the manufacture of filters for gases, vapors and corrosive chemicals, the reinforcement of composite materials (boat hulls, bodywork, sports equipment, etc.), optics and telecommunications ( glass fibers transmit light and therefore information very well)
