The munitions industry uses high-strength carbon fiber composites imported from other countries because of the lack of the information about the properties that should be satisfied by the domestic high-strength carbon fiber composites. Verification of the applicability of domestic high-strength carbon fiber composites to the munitions industry requires comparison of the fiber strength transition rate between the carbon fiber composites imported from other countries and domestically. A strand test was performed to evaluate in the unit of a fiber the mechanical properties of the imported high-strength carbon fiber composites and domestically. Additionally, a composite pressure vessel was prepared using the filament winding method to perform a hydrostatic pressure test and calculate the fiber strength in the unit of a structure. Comparison of the fiber strength results showed that the fiber strength transition rates of the domestic carbon fiber composites H2550 and H3055, were 86.35 and 74.19%, respectively. Domestic carbon fiber composite material H2550 is expected to be replaceable in the munitions industry.
