Compared with the traditional zirconium alloy cladding material, the ceramic fuel cladding material has better high-temperature oxidation resistance and strength, and therefore, the ceramic fuel cladding material is one of important candidate materials of accident-resistant fuel cladding materials. In the process of developing the cladding material for the reactor, in-reactor irradiation performance verification is required, and mechanical property changes such as material strength are measured. At present, the ceramic fuel cladding result form at home and abroad mainly takes a ceramic fiber bundle reinforced ceramic matrix as a main form, so that the irradiation tensile property data of the ceramic fiber bundle also becomes one of important reference indexes in the research and development process of the ceramic cladding material. Ceramic fiber bundles generally have tens to hundreds of dispersed fibers in different compositions, and the state is relatively loose, and each fiber in the fiber bundles is required to be uniformly stressed during a tensile test, so that the loose state is avoided. At present, the conventional method before irradiation is to perform pre-tightening bundling treatment on a fiber bundle through a metal frame before the fiber is subjected to a tensile test, and then perform curing treatment on the fiber in a pre-tightening bundling state through resin glue solution. Because the irradiation test temperature of the ceramic fiber bundle is far higher than the melting temperature of the resin, the ceramic fiber bundle must be pre-tightened and bundled in the irradiation test process of the ceramic fiber bundle.
