The market demand for thermosetting prepregs is strong and has huge development potential in the aerospace field.

Thermosetting prepreg refers to fibers or fabrics prepared from thermosetting resin as raw material by impregnation, drying and other processes using dry or wet methods. According to different raw materials, thermosetting prepregs can be divided into epoxy prepregs, phenolic prepregs, BMI prepregs, etc.

There are many methods for preparing thermosetting prepregs, including hot melt method, solution method, roller winding method, etc. Hot melt method, also known as dry method and hot melt impregnation method, refers to a preparation method in which resin is melted at high temperature and finally made into thermosetting prepreg through processes such as impregnation, extrusion, and drying. The hot melt method has higher requirements for the fluidity of the resin matrix and can better control the accuracy of the resin content of the prepreg. The thermosetting prepreg produced has the advantages of long service life and low harm to the human body. It is the current global thermosetting prepreg. Mainstream preparation methods.

According to the “2022-2027 China Thermosetting Prepreg Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , thermosetting prepreg raw materials include polyimide resin (PI), epoxy resin (ER), phenolic resin (PF), triazine A resin (CE), bismaleimide resin (BMI) and other synthetic resins . In recent years, my country’s synthetic resin production technology has continued to make breakthroughs, and its production capacity and output have been significantly increased. Taking phenolic resin as an example, my country’s phenolic resin industry has a production capacity of 1.896 million tons and an output of 1.678 million tons in 2021. Benefiting from the sufficient supply of raw materials, my country’s thermoset prepreg production continues to increase.

Thermosetting prepregs are mainly used in automobile manufacturing, military industry, national defense, aerospace and other fields. Driven by technological innovation, my country’s thermosetting prepregs have been widely used in the aerospace field, including aerospace engines, civil aircraft, launch vehicles, etc. At present, my country’s large aircraft parts mostly use thermosetting prepreg as the main raw material. Under the influence of positive factors such as national policy support and rapid economic development, my country’s aerospace industry has developed rapidly. In 2021, my country’s aviation engine revenue will reach 27.35 billion yuan, a year-on-year increase of 4.6%. As the application fields continue to expand, my country’s thermosetting prepreg market space will further expand.

In the global market, Hexcel of the United States, Toray Composites of Japan, Solvay of Belgium, and PKE of the United States are world-renowned thermoset prepreg manufacturers, occupying a dominant position in the global thermoset prepreg market.

In the local market, AVIC Aviation High-Tech Co., Ltd., as the leading thermosetting prepreg company in my country, occupies a monopoly in the field of aviation prepregs. In recent years, benefiting from the increasingly strong market demand, the scale of my country’s local thermosetting prepreg companies has continued to expand, driving the localization rate of products to continue to increase. Industry analysts said that with the gradual release of market demand, my country’s thermosetting prepreg industry will gain broad development prospects.
