First trial of SiC/SiC tube fabrication for tungsten monoblock armor

This article is reporting the practical steps of the first trial fabrication of SiC/SiC tube with tungsten mono bloc armor which it is applicable for fusion reactors actively cooling system, where the proceeding to fabricate actively cooling system during the fusion reaction is very important; to decrease the large amount of heat flux produced from neutron irradiation, so the FEEMA project inside Muroran institute of technology has taken an anticipated trial to fabricate this mock up to contribute actively towards the future fusion reactors. The facilities which have been used during the experimental work representing on the infiltration machines to produce both of prepreg sheets and preform by NITE process, and warm isostatic press (WIP), as well as hot isostatic process (HIP). this works recorded the positives and drawback of the produced tube of SiC/SiC regarding to its durability, as well, its microstructure evolution. The optimum conditions of WIP for the SiC/SiC tube was the key element to produce high durable SiC/SiC tube in HIP stage. the results showed that; WIP conditions; of applied pressure; 6.5 Mpa, temperature 80 °C, and holding time 6 h, such conditions showed that the resulted SiC/SiC tube after HIP recorded maximum tensile strength up to 286 Mpa.
