In 2017, in Shanting Town, Putian City, Fujian Province, Alibaba’s Cainiao Network tested a cross-sea drone delivery group consisting of 18 drones, forming a triangle formation in the air, facing the gust of level 6 and 7, fully loaded with Mae The six boxes of goods ordered by Zhoudao residents successfully flew across the strait in just 9 minutes, successfully providing diversified logistics services for rural Taobao.

Of course, there are still many problems in the specific practical application of express delivery drones, such as safety issues. This is a difficult problem in the design of drones. Up to 2 kilometers, specially used to deliver packages not exceeding 500 grams. It comes with a protective cage, which is made of carbon fiber material. During the flight, the entire drone and package are in the protective cage. If there is any accident on the way, the protective cage can play a very good role in protection;

Although the above-mentioned UAVs are guaranteed in terms of safety, their loads are too small to meet most express delivery needs, and it is difficult to use them for a long time in terms of battery life. Taking the currently widely used electric drone as an example, after an average charge once, it can fly about 10 kilometers in 10 minutes. Considering the return journey, the delivery range of the electric drone is within 5 kilometers. As a high-frequency express unmanned Machine, this endurance is far from enough.

The application and development potential of carbon fiber composite materials in the field of express drones is huge
