The invention relates to preparation of
nuclear radiation protective materials, in particular to a preparation method of
composite material tube-shaped parts used for a
nuclear reactor moderated
neutron. For solving the problem that for an existing preparation method of the
composite material tube-shaped parts used for the
nuclear reactor moderated
neutron, the technological process is relativelycomplicated, and meanwhile, shaping of the tube-shaped parts adopts a
welding technology, so that the made tube-shaped parts are not good enough in performance, the preparation method of the compositematerial tube-shaped parts used for the
nuclear reactor moderated
neutron adopts a
spark plasma sintering technique to prepare an aluminum base
graphite composite material blank. Mechanical
processing is conducted on the aluminum base
graphite composite material blank prepared through
sintering. More than one time of
spinning forming is conducted on the aluminum base
graphite composite material blank after mechanical
processing by using a method of strong
spinning, and finally, a thin-walled tube-shaped part is formed by
spinning.
Spinning is beneficial for improving mechanical properties such as density, strength and
hardness of the composite materials, and meanwhile the using ratio of the materials is improved, and the manufacturing cost is reduced. A prepared finished product can be used for spent
fuel storage as well as a
nuclear power station middle tube-shaped shielding body and the preparation method of the composite material tube-shaped parts used for the nuclear reactor moderated neutron is an advanced method for preparation of the composite material tube-shaped parts.
