Fiberglass reinforced plastic (FRP) is a composite material composed of glass fibers and a plastic matrix (such as polyester, epoxy resin, etc.). FRP is widely used in construction, chemical industry, ship, automobile, aerospace and other fields because of its light weight, high strength, corrosion resistance, insulation and other characteristics.
The service life of fiberglass is affected by various factors, including:
1. Material quality: High quality fiberglass materials can provide a longer service life. Choosing the appropriate type of resin and glass fiber, as well as the correct manufacturing process, is the key to ensuring the performance of fiberglass.
2. Usage environment: Fiberglass exhibits different durability in different usage environments. For example, under dry and room temperature conditions, fiberglass has a longer service life; In humid, high-temperature, or chemically corrosive environments, its durability will decrease.
3. Maintenance: Regular maintenance can extend the service life of fiberglass. For example, regularly cleaning the surface to prevent the accumulation of dirt and chemicals can reduce corrosion and aging.
4. Design and application: Reasonable design and application can ensure that fiberglass performs at its best under expected usage conditions. For example, avoiding excessive loads and impacts can reduce material fatigue and damage.
5. Manufacturing process: Adopting advanced manufacturing processes such as vacuum assisted resin transfer molding (VARTM) can improve the quality and durability of fiberglass products.
Generally speaking, the service life of fiberglass can reach over 20 years, or even longer. In some specific applications, such as ships, chemical equipment, etc., the service life of fiberglass can reach 30 years or longer. However, the specific service life still needs to be determined based on actual usage conditions and maintenance.
In China, the development of the fiberglass industry has received support from national policies, especially in areas such as energy conservation, emission reduction, and green manufacturing. With the advancement of technology and the expansion of application fields, the service life and performance of fiberglass will be further improved. At the same time, China is constantly strengthening the quality supervision of fiberglass products to ensure their safe application in various fields.
