Are tempered glass and glass fiber steel the same substance?
Glass fiber reinforced plastic is a new type of composite material developed in early twentieth Century. It has many advantages, such as light weight, high strength, anticorrosion, heat preservation, insulation, sound insulation and so on. FRP doors and windows with glass fiber roving and its fabric as reinforcing material, using unsaturated resin as matrix material, through a special process to compound the two kinds of materials, and add other mineral filler, and then cured by heating, extruding into various hollow sections and different processing section. Specifically, the main features of FRP doors and windows are: anti-aging, high strength. The hollow section of the glass fiber reinforced plastic section is not lined with steel plates as an inner lining, and does not need any single material auxiliary reinforcement, and the structure is completely supported by the support of the structure itself. Due to the glass fiber and its fabric as reinforcing material, without filament resin bonding bare, by mechanical thermal curing pultrusion molding, so the bending and bending and deformation. Corrosion resistance and long service life.
The other is to change the composition of the surface of glass by means of ion exchange in ordinary flat glass or float glass, thus forming a laminated stress layer on the surface of glass. Tempered glass has a high impact resistance (4~5 times higher than ordinary flat glass), bending strength (5 times higher than ordinary flat glass), good thermal stability, and bright and clean, transparent and can be cut. In case of super impact damage, the debris is scattered, small particles, no sharp edges and corners, it is also known as safety glass. Tempered glass is divided into flat tempered glass and curved tempered glass according to its shape. Flat tempered glass thickness of 4, 5, 6, 8, 10, 12, 15, 19mm eight; curved tempered glass thickness of 5, 6, 8mm three. Tempered glass according to its appearance quality is divided into: excellent products, qualified products of two kinds. Tempered glass is divided into I, II and III by fragmentation.
Reinforced plastics made from glass fiber or its products are referred to as glass fiber reinforced plastics or glass fiber reinforced plastics. Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. Glass fiber reinforced plastics are transparent and opaque. Ordinary steel is only a combination of iron and carbon, while the composition of FRP is complicated.
