Hengshen’s carbon fibre rocket supporting cabin passed the static test

China’s major carbon fibre and composite materials producer Hengshen announced that the supporting cabin of the main load-bearing part of a civil rocket that the company developed, designed and manufactured, passed the static test assessment in Shanghai. After a 20-day load test, it finally ended with the ultimate bearing capacity exceeding the design load by more than 120%.

The rocket support cabin is the key main load-bearing component of the launch vehicle to carry the satellite. It is located between the last stage power cabin of the rocket and the satellite, and is an important load-bearing and connecting structure in the rocket structure.

Hengshen indicates that the support module will be used to carry the Zhuque-2 launch vehicle, with a total weight of more than 200 tons. In order to achieve the goal of weight reduction under complex load conditions for satellite launches, the support cabin adopts a carbon fibre composite material foam sandwich structure design scheme, and uses the EM817B resin system prepreg independently developed by Hengshen. By optimizing the structural design, the difficulty in the molding process of the foam sandwich structure in the load concentration area has been overcome. Compared with the original metal support cabin, the weight has been reduced by 42.3%, and the ultimate carrying capacity has been improved by more than 50%.It has great potential for commercial application in the development of civil launch vehicles, says Hengshen.

The Hengshen support cabin project was launched in the Advanced Manufacturing Division in April 2022, and the first delivery was completed in April 2023. After the start of the project, the business department organized a cross-departmental and cross-professional project research team to achieve cooperation of professional technicians and operators in structure, strength, process, mold, assembly and quality. This enabled the first part of the project to be delivered on schedule.

According to the project manager, the rocket support module is the first delivery of Hengshen’s composite material parts segment in the commercial aerospace field, marking a major breakthrough in Hengshen’s commercial aerospace composite manufacturing capacity. At the same time, it also marks that Hengshen has taken a solid step in commercial aerospace composite parts and components manufacturing.
