·China's carbon nanotube rubber project has been successfully used for aircraft tires
Recently, Taicang Guanlian Polymer Materials Co., Ltd. has successfully achieved the carbon nanotube rubber project jointly developed by domestic universities and colleges, and is currently accepting the scientific and technological department of Jiangsu Province. Due to the strict requirements of high impact strength and low heat build-up, aircraft rubber tires have long been monopolized by foreign manufacturers. After the carbon nanotube rubber is put into production, it can be applied to aviation tires, which is expected to break the technological monopoly of foreign companies.

Technical advantages:
1. Excellent and efficient processing: Five-axis linkage of the bus system realizes space leapfrog and flying cutting technology, and improves efficiency by more than 20-50%.
2. Pipe cutting system: user-friendly and easy to operate, with sufficient pipe process database.
3. Special bed design:reinforced integrated welding bed, after annealing and twice aging treatment, with good stability.
4. Simple and convenient maintenance: the front chuck has good sealing performance and is more durable against dust; The rear chuck blows air automatically, and the pipe wall is cleaner.
5. Automatic feeding rack(optional): realize automatic clamping, pushing and accurate feeding with fast cyclic feeding speed.
6. Good quality and high precision: front and rear full stroke precision pneumatic chuck, multi axis linkage at the same time, good cutting effect and high precision.
7. A15: Double chuck short tailing:the cutting head spans from the front to the back of the front chuck and cuts the last workpiece.The tailing ≥ 40mm can save more material costs.
8. Excellent processing performance: it adopts high rigidity thickened bed, with bus pipe cutting system and bus motor which has faster processing speed and higher precision.
9. Slag extraction system (optional): solve the problem that there is no residue on the inner wall of the pipe, eliminating the secondary vibration polishing process.
10. High efficiency feeding system (optional): high rigidity design of feeding rack, stable and fast feeding and refueling, and the cycle time is about 10 seconds.

According to reports, the rubber material used for aircraft tires must be tested under the harsh conditions of -40 ° C and above and above 71 ° C for 24 hours, the bursting pressure of the tire must be able to withstand the extreme pressure of the fuselage when landing, the tires when the aircraft takes off and landing The generated static charge should be transmitted evenly to the ground. The company's R&D manager, Jing Lei, introduced that carbon nanotubes are one-dimensional nanomaterials with hardness comparable to diamonds, but they have good flexibility and can be used to make bulletproof garments. How to apply carbon nanotubes to the production of rubber has always been a technical problem in the industry. In order to develop carbon nanotube rubber, Guanlian relied on the university's production, research and research base, and the company's technical staff worked closely with the university's long-term experts to continuously overcome technical difficulties and finally achieved success. “At present, we are applying for a doctoral student workstation in Jiangsu Province,†said Jing Lei. “Next, we will conduct a full range of industry-university-research cooperation in the development and industrialization of high-performance rubber materials for aviation tires.â€
