The main material difference between fiberglass cloth and glass
Fiberglass grid cloth is a non-twisted roving plain weave fabric, which is an important base material for hand lay-up FRP. The strength of the square cloth is mainly in the warp and weft directions of the fabric. For occasions that require high warp or weft strength, it can also be woven into unidirectional fabrics. It can arrange more untwisted rovings in the warp or weft directions. Warp to fabric, single weft to fabric.
Fiberglass cloth is made by drawing glass into extremely fine glass filaments, and the glass filaments at this time have good flexibility. The glass filaments are spun into yarns, and then passed through a loom to weave into glass fiber cloth. Because the glass filament is extremely thin and the surface area per unit mass is large, the temperature resistance performance is reduced. It is like melting a thin copper wire with a candle. But glass doesn't burn. The burning we can see is actually the resin material coated on the surface of the glass fiber cloth, or the attached impurities in order to improve the performance of the glass fiber cloth. Pure fiberglass cloth or coated with some high-temperature-resistant coatings can be used to make products such as fire-resistant clothing, fire-resistant gloves, and fire-resistant blankets. However, if it comes into direct contact with the skin, the broken fibers will be more irritating to the skin and will be very itchy.
Fiberglass cloth is mostly used in hand lay-up process, and fiberglass reinforced material grid cloth is mainly used in ship hulls, storage tanks, cooling towers, ships, vehicles, tanks, and building structural materials. Fiberglass cloth is mainly used in industry: heat insulation, fire prevention, flame retardant. The material absorbs a lot of heat when it is burned by a flame and can prevent the flame from passing through and isolate the air.
1. According to the composition: mainly medium-alkali, non-alkali, high-alkali (to classify the composition of alkali metal oxides in glass fiber), of course, there are also classifications by other ingredients, but there are too many varieties, not one by one enumerate.
2. According to the manufacturing process: crucible wire drawing and pool kiln wire drawing.
3. According to the variety: there are ply yarn, direct yarn, jet yarn, etc.
In addition, they are distinguished by single fiber diameter, TEX number, twist, and sizing type. The classification of glass fiber cloth is similar to the classification of fiber yarn. In addition to the above, it also includes: weaving method, gram weight, width, etc.
The main material difference between fiberglass cloth and glass: The main material difference between glass fiber cloth and glass is not big, mainly due to the different material requirements during production, so there are some differences in formula. The silica content of flat glass is about 70-75%, and the silica content of glass fiber is generally below 60%.
