The general development direction of nano-carbon fiber composite materials will be expanded from dual composite to multiple composite. The main trend of the development of nano-carbon fiber composite materials is structural materials. In the future, it will be based on structural nano-carbon fiber composite materials, and develop towards functional and multi-functional nano-carbon fiber composite materials. In terms of weaving technology, it will develop from one direction to many directions. Knitting puncture technology is an inevitable trend of development. From the perspective of machine knitting technology, foreign countries are developing from simple machinery to highly mechanized, microcomputerized and computer-controlled fully automated. For example, research in the United States has entered the stage of computer simulation.

In terms of the application of nano-carbon fiber composite materials, advanced aircraft have been developed to the general aviation and automotive fields. For example, France and Japan use nano-carbon fiber composite materials in general aviation and automotive industries as brake materials. The general development trend of the world's nano-carbon fiber composite application research is to develop in depth, toward civilian use and low cost.

In addition, pores are an important part of the volume of nano-carbon fiber composite materials, which are beneficial to ensure impact resistance and thermal vibration resistance. The number of pores and their influence on the properties of nano-carbon fiber composites are worth studying. Therefore, how to maintain certain pores of nano-carbon fiber composite materials and improve their high-temperature oxidation resistance is one of the focuses of future development.

To sum up, the application of nano-carbon fiber composite materials is currently only in the field of aerospace into general aviation and other general industrial fields. If carbon nano-fiber composite materials can be used in high-temperature structural parts in the non-aerospace field, it will cause a major technological change in the non-aerospace field, and change the market structure of nano-carbon fiber composite applications, widely replacing other materials. It is expected that in the first half of the 21st century, nano-carbon fiber composite materials will become a promising high-temperature application composite material.
