3.insulation performance:

Because glass fiber is a non-conductive material, it has good insulation performance. Therefore. It is commonly used in the power industry to make insulation materials. Manufacture cable protective sleeve and other products.

4.thermal stability:

Glass fiber has good thermal stability. It can maintain the stability and performance of the structure under high temperature environment. This makes it ideal for refractories and insulation. Widely used in construction and aerospace and other fields.

5, transparency:

glass fiber has good transparency, can be made into transparent composite materials. This makes it useful in areas such as optical communications. Such as optical fiber communication and optical instruments.

6, light weight:

compared with metal materials, glass fiber has a lighter weight. This makes it widely used in fields such as automotive and aerospace. Can reduce the overall weight. Improved fuel efficiency and load carrying capacity.

Generally speaking. The properties of glass fiber include strength and toughness. Corrosion resistance. Insulation properties. Thermal stability. Transparency and light weight. These properties make glass fiber a versatile material. Widely used in various fields.

(3) The effect of storage time on glass fiber

Glass fiber is a kind of material widely used in construction, automobile, aviation and other fields, its long-term storage will affect its performance. This paper will discuss the effect of storage time on glass fiber from the following aspects.

1, strength and toughness:

The strength and toughness of glass fiber is one of its most important characteristics. Long-term storage may result in the degradation of these characteristics. Research shows. Glass fibers are exposed to high temperature and humidity for a long time. Microcracks are produced, reducing its strength and toughness.

2, corrosion resistance:

Glass fiber has good corrosion resistance. However, long-term storage may cause its corrosion resistance to decline. This is because of long-term storage. Dust and contaminants will accumulate on the surface of the glass fiber. Cause surface damage. Plus. Glass fibers may corrode after prolonged exposure to moisture. The performance deteriorates.

3, thermal stability:

Glass fiber has good thermal stability. However, long-term storage will affect its high temperature resistance. Exposure to high temperatures for long periods of time. Fiberglass may lose its thermal stability. The performance deteriorates.

4, insulation performance:

Glass fiber has good insulating properties. However, long-term storage may affect its insulation performance. Long-term storage meeting. Dust and contaminants accumulate on the surface of the glass fiber. Cause its surface resistance to decrease. Thus affecting its insulation performance.

5, appearance quality:

Glass fiber as exterior material. Problems such as discoloration and fading may occur after long-term storage. Thus affecting its beauty and quality.

To sum up. The effect of long-term storage on glass fiber includes a decrease in strength and toughness. Corrosion resistance decreased. Thermal stability decreased. Insulation performance deteriorates. Appearance quality damage, etc. Therefore. In practical application. Attention must be paid to the proper preservation and maintenance of glass fibers. To maximize its service life. It is recommended to store fiberglass in a dry and ventilated and cool place. And regular cleaning and maintenance.

(4) Summary

Glass fiber has a long history. As early as the 1930s, people began to try to prepare fiber-like glass materials.However. Until the 1950s. Commercial glass fibers were successfully produced. Thereafter. Glass fiber is widely used in construction and automotive and aviation.

The characteristics of glass fiber make it an ideal material. First of all, it has good strength and toughness, and can withstand high pressure and impact. Second. Glass fiber has excellent corrosion resistance. Immune to acid. Erosion by alkali and other chemicals. Besides. Glass fiber also has good insulation properties. It can block the conduction of electricity. In the meantime. It also has good thermal stability. It also maintains stable performance in high temperature environment. Besides. Glass fiber also has the characteristics of light weight and flexibility and transparency. Make it widely used in various fields.

However, long-term storage may have a certain impact on the glass fiber. First, storage time is too long may lead to a decline in the strength and toughness of the glass fiber, because prolonged exposure to high temperature and humidity will lead to the production of micro-cracks. Second, long-term storage may reduce the corrosion resistance and thermal stability of the glass fiber, because of the accumulation of dust and contaminants on the surface, and prolonged exposure to humid environments may cause corrosion. In addition, long-term storage may also affect the insulation properties and appearance quality of glass fiber.

In summary, glass fiber as an important material has many excellent characteristics, but long-term storage may have a negative impact on its performance. Therefore, when using glass fiber, it is necessary to pay attention to proper preservation and maintenance to extend its life and maintain good performance.
