What is the development trend of fiberglass composite materials?
1. At present, high-performance fiberglass has great development potential, especially high-silica fiberglass has great advantages. There are two development trends of high-performance fiberglass: one is to focus on higher performance, and the other is to focus on the industrial technology research of high-performance fiberglass, and strive to improve the process performance of high-performance fiberglass, while reducing costs and reducing pollution.
2. There are some shortcomings in material preparation: the preparation of some high-performance fiberglass still has problems such as glass crystallization, high raw fiber density, and high cost. At the same time, it cannot meet the requirements of strength and other requirements in some special uses. When thermosetting resin is used as the matrix, the prepared composite material has the problems of difficulty in secondary processing and recycling. It can only be processed by cutting. Recycling can only be carried out by special chemical solvents and strong oxidants. The effect is not ideal. Although degradable thermosetting resins have been developed, the cost problem still needs to be controlled.
3. In the synthesis process of fiberglass, new fiberglass composite materials are prepared with the help of various synthesis technologies. In recent years, in order to meet the needs under various special conditions, various surface technologies have been developed to perform special modification on the surface of fiberglass. Surface modification is a new trend in the development of fiberglass composite material preparation technology in the future.
4. In the future, global market demand, especially the demand in emerging market countries, will continue to maintain a high growth rate, and the advantages of industry leaders will become more obvious. For example, China's fiberglass enterprises represented by Jushi Group will play a leading and guiding role in the global glass fiber industry in the future. Glass fiber composite materials have become one of the main raw materials in the automotive industry. fiberglass thermoplastic materials have a growing application trend due to their good economy and good recyclability. At present, the application scope of widely used fiberglass thermoplastic reinforced materials includes instrument panel brackets, front brackets, bumpers and engine peripheral components, covering most parts and secondary structures of the whole vehicle.
5. In addition to several major fiberglass production bases, small and medium-sized enterprises account for 35% of my country's fiberglass industry output. Most of them have a single variety, weak technology, and more than 90% of the total number of employees. They have limited resources and poor management of business risks. They are the focus and difficulty of the industry's implementation of strategic transformation. We should actively support and guide small and medium-sized enterprises to take the path of coordinated development, and achieve the goal of development by forming small and medium-sized enterprise groups and strengthening cooperation and competition with the outside world. With the mutual penetration of the economy, the competition between enterprises is no longer a single fight, but a collaboration and alliance.
