Characteristics of Glass Fiber

The Glass Itself Has Many Good Physical Properties. It Has Been Used Abroad Since Ancient Times.
After the commercial manufacture of the glass fiber filaments of A.D. in 1930, due to its good physical properties, it expanded the field of use of glass, especially in composite materials.
In order to adapt to different uses, it is necessary to adjust the production direction of glass fiber. And S glass (for high tension), E glass (for electronic level), C glass (for chemical burning)
General physical properties of glass fiber filaments:
- High tension-endurance: the tension-resistant is about twice as steel of unit weight.
- Good size stability: the ratio of elongation is about 3% ~ 4%.
- Good heat-endurance: it have the 50% ability of tension-endurance however the temperature of 340℃.
- The character of the resistance to chemical cauterization: it is not easy to be damaged by the chemical.
- Low heat expansion.
- Low water-absorptance: 0.1%.
- Good electronic characters: is has good electric-resistant.
- Good flame-resistent: the melting point of glass is high, so it has the character of non- burning.
Due to its good quality and low cost, glass fiber has become the most commonly used reinforcing material in foreign countries.
Composite materials made abroad have replaced some common traditional materials such as metal and wood.
The manufacture of glass wool is to mix and melt various raw materials for glass production in a furnace of about 1300 ° C, and then use the gravity to make the molten slurry pass through a spinning box and extract it into a private fiber with a diameter of several μm (10*-6). Between the two, then dozens of hundreds of glass sizing, high-speed coiling into a silk cake, silk cake according to the needs of the need to re-process into a stranded mat, diced strands, braided yarn, yarn and other product. The silk cake is processed into a bobbin by a twisting machine, which is a basic raw material for manufacturing a glass fiber cloth. The glass yarn which used in the electronic grade fiberglass cloth is E-glass.
