Outdoor Furniture Material of Fiberglass Advantages And Disadvantages

As a special composite material, FRP is widely used in outdoor furniture with its unique performance characteristics. However, like any other material, FRP has its own unique advantages and disadvantages. Next, we will discuss the advantages and disadvantages of FRP in depth.

I. Advantages of FRP

1. Light weight and high strength

FRP stands out from other materials because of its lightweight and high strength. Compared with traditional metal materials, FRP has a lower density, which makes it better portable and processable while ensuring strength. At the same time, its specific strength even exceeds that of some alloy steels, offering more possibilities for structural engineering.

2. Excellent corrosion resistance

FRP has excellent corrosion resistance to most chemicals and can be used for a long time in harsh environments. Whether it is acid, alkali, salt and other chemicals, or seawater, sewage and other complex environments, FRP can maintain good stability and durability. This characteristic makes FRP has a wide range of application prospects in chemical industry, ocean engineering and other fields.

3. Excellent electrical properties

FRP is an excellent insulating material, which can effectively isolate current and heat conduction. This makes it widely used in electric power, electronics and other fields. [...]

4. Thermal stability

Fiberglass reinforced plastic (FRP) has good thermal stability and heat resistance, and can be used in high-temperature environments. Although its long-term temperature resistance is relatively poor, its high temperature resistance can be improved to a certain extent by choosing suitable high temperature resistant resin for use in conjunction. This makes FRP valuable for application in high temperature process, thermal equipment and other fields.

5. Flexible design

FRP products can be molded into various shapes and sizes to meet different needs. This design flexibility makes FRP widely used in architectural design, decorative arts and other fields. At the same time, FRP products have smooth surface and various colors, which can be made into products with artistic sense and add beauty to people's life.

6. Low comprehensive cost

Although the manufacturing cost of FRP is relatively high, but considering its long service life, low maintenance cost and other characteristics, its comprehensive cost is not higher than traditional materials. In some long-term use of occasions, such as chemical equipment, marine platforms, etc., the use of FRP materials can significantly reduce the maintenance cost and cost of use.

II. Disadvantages of FRP

1. Low modulus of elasticity

Compared with metal materials, FRP has low modulus of elasticity and is prone to deformation. This makes the application of FRP in some occasions requiring high-precision dimensional control, such as the manufacture of precision instruments and other fields, is somewhat limited. However, the modulus of elasticity of FRP can be improved to a certain extent by choosing suitable reinforcing materials and molding process.

2. Poor long-term temperature resistance

When FRP is used for a long time in a high temperature environment, aging phenomenon may occur, reducing its service life. In order to overcome this shortcoming, you can choose to use high temperature resistant resin for use to improve its high temperature resistance. However, it should be noted that, even with the use of high-temperature-resistant resin, the long-term temperature resistance of FRP is still limited, and needs to be selected according to the specific use of the occasion.

3. Low interlayer shear strength

FRP products are prone to interlayer peeling or cracking when subjected to shear. This is mainly due to the weak interlayer bonding of FRP products. In order to overcome this shortcoming, you can increase the interlayer bonding force in the manufacturing process or use other enhancement measures to improve its interlayer shear strength.

4. Vulnerable to ultraviolet light

Exposed to UV rays for a long time, FRP may suffer from color changes, surface cracking and other problems, reducing its aesthetics and service life. In order to overcome this disadvantage, the surface of FRP products can be coated with a layer of anti-UV coating or use other protective measures to protect the surface.

5. Weak impact resistance Compared with metal materials, FRP has poor impact resistance and is prone to cracking or breaking. Therefore, it needs to be used with caution in some high impact load applications. However, in some low impact load occasions, such as building decoration and other fields, FRP still has a wide range of application prospects.
