Recently, a new high-strength and high-modulus carbon fiber developed by the carbon fiber and composite materials team of NBCL Carbon Fiber Technology Group as raw materials, a high-end badminton racket prepared by fine design and molding processing has been successfully launched on the market. This is called a full carbon ultra-light carbon fiber badminton racket. The latest carbon fiber is used to balance the stiffness and strength of the badminton racket, and the weight is only 71g (excluding the weight of the net rope).
Compared with the traditional carbon fiber badminton rackets currently on the market, this product is characterized by the use of special carbon fiber materials with better performance, that is, the tensile strength 5200-5300MPa and the tensile modulus 330- independently developed by the carbon fiber and its composite material team. 340GPa new high-strength high-modulus carbon fiber.
By using this type of carbon fiber as a raw material, the overall performance of the badminton racket can be improved, and the weight of the racket can be further reduced, making the final product weigh only 71g.

Description: The shaft of the badminton racket is made of 100% carbon fiber, and the weight of the badminton racket is about 88 grams.
Advantages of NBCL's carbon fiber badminton racket
The key to the overall performance and price of carbon fiber badminton rackets lies in the type of carbon fiber selected. According to the carbon fiber raw materials in the above-mentioned products and the professional knowledge of the editor, the current use of carbon fiber in badminton rackets is Japanese Toray T700 high-strength carbon fiber and M40J high-modulus. Mainly carbon fiber, of course, other types of carbon fiber such as M46J high modulus carbon fiber, T1000 and even T1100 high-strength carbon fiber will also appear in extremely high-end badminton rackets.
From the perspective of fiber performance analysis: T700 carbon fiber has a tensile strength of 4900MPa and a tensile modulus of 230GPa, while M40J carbon fiber has a tensile strength of 4410MPa and a tensile modulus of 377GPa.
Through the comparison between the two, it is not difficult to find that the advantage of T700 carbon fiber is that it has higher strength, so it can ensure that the racket has high strength when used in badminton rackets; and the modulus of M40J carbon fiber is much higher than T700 carbon fiber, so it can give badminton rackets high rigidity.
Analysis from the perspective of fiber cost: T700 carbon fiber, as the flagship product of Toray's industrial-grade carbon fiber products, has long occupied a large market share due to its low price, and its price is about 100-200 yuan/kg.
In contrast, the price of M40J carbon fiber is close to 10 times that of T700 carbon fiber. Therefore, the different fiber materials used in badminton rackets lead to different prices. Sometimes in order to meet the needs of strength, rigidity and lightweight at the same time, some badminton rackets will choose T700 and M40J carbon fiber mixed use.
In the design and processing of carbon fiber badminton rackets, if only T700 carbon fiber is used, due to the low fiber modulus, in order to ensure the rigidity of the racket, the amount of fiber used will be increased. The final result is a significant increase in the weight of the badminton racket. Unfavorable hand feeling brought by the user;
In contrast, the use of HM carbon fiber can ensure rigidity with a small amount, so the racket weight is slightly lower. For example, among the above-mentioned hot-selling badminton rackets, the heaviest carbon fiber badminton racket exceeds 100g, while the HM carbon fiber racket can be as low as 80 grams.
In order to meet the requirements of rigidity and strength for products in special fields, NBCL carbon fiber and its composite material team successfully developed a new type of carbon fiber with a tensile strength of 5200-5300MPa and a tensile modulus of 330-340GPa, and achieved stable batch production. Work in the early stage The Chinese team used this type of carbon fiber to process and prepare high-pressure hydrogen storage bottles with excellent performance, and passed tests in related fields. This time, this type of carbon fiber was once again applied to badminton rackets.
It can be found from the fiber properties that the tensile strength of this new type of carbon fiber is slightly higher than that of T700 carbon fiber, but its modulus is about 100 GPa higher than that of T700 carbon fiber. Although the modulus is lower than that of M40J carbon fiber, the difference is not large, and the fiber strength It is nearly 1000MPa higher than M40J carbon fiber, so it truly achieves the balance of performance of T700 and M40J carbon fiber.
After the fine process design and regulation of the cooperative supplier, the weight of the new carbon fiber badminton racket is only 71g, which makes the racket feel very good.
