Hot pressing, cold pressing followed by hot pressing, and vacuum injection casting have been employed to produce fiberglas-reinforced core material. The starting material was aluminum-coated fiberglas. Calculations have indicated that the loading of the core section of a regular MTR fuel plate can be accomplished by using an aluminumcoated fibenglas in which the glass cortains 50 per cent U/sub 3/O/sub 8/ by weight. The aluminum coating would be approximately 60% by volume, while the glass content would be 40% by volume. The unclad fabricated fiberglas-reinforced aluminum has exhibited tensile strengths up to 22,000 psi at room temperature. The elongation and reduction in area were normally less than one per cent. The unclad material normally bent only 7 to 10 degrees around a 1/4-in radius. Cladding this material with 1100 aluminum increased the formability to the extent that it bent up to 90 degrees around an identical radius without breaking. The clad material exhibited reductions in area up to 47%, elongations up to 14%, and tensile strengths up to 19,250 psi at room temperature. Cladding the fiberglas-reinforced aluminum produced blister- free plates. To date, the physical properties of the clad fiberglas-reinforced aluminum have been comparable to a clad plate containing an aluminum-uranium core section. (auth)
