Kite was invented by ancient Chinese laborers during the Spring and Autumn Period of the Eastern Zhou Dynasty, dating back over 2000 years. According to legend, Mozi made wooden birds from wood and developed them for three years, making it the earliest origin of kites for humans. Later, Lu Ban used bamboo to improve the material of Mo Zhai's kites. It was not until the Eastern Han Dynasty, when Cai Lun improved his papermaking skills, that people began to use paper to make kites, known as "paper kites".

During the Northern and Southern Dynasties, kites began to become tools for transmitting information; Starting from the Sui and Tang dynasties, due to the development of papermaking, people began to use paper to frame kites; In the Song Dynasty, flying kites became a popular outdoor activity among people.

With the development of the times, kite skeleton materials have changed from wood to bamboo, plastic, etc. Nowadays, carbon fiber is constantly evolving and developing, and people are trying to use it to manufacture kite skeletons.

Carbon fiber tubes have the advantages of high strength, long service life, corrosion resistance, light weight, and low density, and are widely used in kites.

1. Light weight: If a kite wants to fly in the air, the most important thing is to have light weight. Carbon fiber has a low density, less than 1/4 that of steel.

2. High strength: The strength of carbon fiber pipes can vary due to various factors, including material composition, manufacturing process, and design parameters. Generally speaking, carbon fiber tubes have high strength and stiffness, and are lighter than traditional materials such as steel and aluminum.The tensile strength of carbon fiber is usually 3000MPa; The tensile strength of carbon fiber pipes made by composite with resin matrix is about 1500MPa.

3. Wear resistance: Carbon fiber composite materials are transformed through a series of heat treatments, containing 90% inorganic high chromium. Carbon fiber tubes have the inherent nature of carbon fibers, while also possessing the softness and processability of woven carbon fibers. No matter what products and materials are used, there is a certain amount of wear and tear. Low wear rate leads to long service life; On the contrary, high wear rate results in short service life. However, one of the characteristics of carbon fiber is its wear resistance.
