Engineering plastics refer to a class of plastics that can be used as engineering structural parts because of their low density, high specific strength, excellent wear resistance and low coefficient of friction, high heat resistance, electrical insulation, chemical stability, acid/alkali resistance, and with obvious advantages such as free coloring, easy modification, and good processability, it has been widely used in the fields of automobiles, electronics, electrical, communications, transportation, aerospace, machinery, etc., and has become one of the important symbols to measure a country's industrial development level. Modification of engineering plastics due to the limitation of the performance of a single resin, and people's requirements for low cost, high performance and diversified performance of materials are getting higher and higher, and various modified engineering plastics have emerged as the times require. Engineering plastics can be realized through physical, chemical or a combination of physical and chemical methods, including blending (alloying), copolymerization (grafting), and filling reinforcement. Modification can significantly improve the performance of engineering plastics. In addition, one polymer matrix can be used to produce a variety of products with different uses. The production operation is flexible, and it is easy to realize one machine with multiple functions, and realize the serialization and specialization of products.

The aviation industry has always been equipped with strict quality system certification and highly complex integration technologies. All countries in the world regard the aviation industry as an indicator of national industrial technical capabilities.

Carbon fiber composite materials need to be processed using a molding process from prepreg to the final part. With the development of carbon fiber technology, the molding process of carbon fiber composite materials is also constantly improving. However, various molding processes of carbon fiber composite materials do not exist in the way of updating and eliminating, and often a variety of processes coexist to achieve the best effect under different conditions and different situations.

Carbon neutrality, inflation, and rising energy costs will speed up the restructuring of the textile fiber supply chain. Suppliers with vertically consistent factories and green products are expected to win.

Soft matter is a subfield of condensates that includes a variety of physical states susceptible to thermal stress and thermal fluctuations. Nowadays, it is used in flexible substrates and has become a key material for the development of thinning and flexibility.

The negative electrode material refers to the raw material that constitutes the negative electrode in the battery. The negative electrode of lithium-ion battery is made of negative electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled. The key to the successful fabrication of lithium-ion batteries lies in the preparation of negative electrode materials that can reversibly de/intercalate lithium ions.
