Fiberglas-reinforced aluminum core material was produced by press consolidation of aluminum-coated flberglss. A hot pressing operation furnished materials with an average density of 98.5% of theoretical. Cold pressing followed by hot pressing produced materials with an average density of 99.1% of theoretical. Fabrication techniques for fiberglas-reinforced aluminum were developed with uranium-free glass to the point where crack free core material was produced, both clad and unclad. The material was picture framed, heated to 1000 deg F, and hot rolled with reductions of approximately 30% per pass. As-hot pressed compacts were produced with 60.8% by weihht of aluminum and 39.2% by weight of fiberglas. Specimens of this material in which the fibers were oriented along the specimen axis exhibited a tensile strength of 25,250 psi at room temperature, and maintained a tensile strength of approximately 18,450 psi at 250 to 800 deg F. The tensile strength of the as-hot pressed material in a transverse direction to the oriented fibers was 16,700 psi at room temperature, decreasing rapidly to 4,500 psi at 600 deg F.
