Beginning in 2017, WHTZ carbon fiber composite material Co., Ltd. has provided multiple batches of CCF700S-12K carbon fiber to the 8603 Factory of the Fourth Academy of Aerospace Science and Industry of China, in cooperation with the development of XX solid rocket motor fiber winding shells. The supplied CCF700S-12K carbon fiber has undergone the preliminary sample performance test and engine casing verification, etc., and has undergone the first major assessment to perform a hydraulic blasting test on the fiber wound casing. After the test was confirmed by the Ninth Division of the Fourth Academy of Aerospace Science and Technology and the 8603 Factory of the Fourth Academy of Aerospace Science and Technology, the fiber strength value, strength utilization rate, and shell hydraulic blast pressure fully met the technical requirements.
