Abstract
A panel of neutron shielding material comprises outer sheathing layers of aluminum having therebetween alternate thin layers or plies of aluminum and metallurgically bonded uniform mixtures of aluminum particles and particles of a neutron absorbing material, preferably boron carbide (B.sub.4 C) in which the layers have their major dimensions extending substantially parallel to the outer aluminum layers. In a modified construction, the alternate layers or plies may extend perpendicular to the outer aluminum layers or plies. The assembly is hot rolled to a final thickness, usually about one quarter or one eighth inch, metallurgically bonding the aluminum sheets, strips, and/or particles and the aluminum and boron carbide particles into a continuous mass.
