Abstract : Laminated panels 0.130 inch thick fabricated with 12 plies of fiberglass cloth No. 181, Volan (United States Polymetric Chemicals Co., Stamford, Conn.) and cured at 190 F for 2 hours under 10 to 12 psi vacuum bag pressure. Qualification test outcomes (Mil-P-8013C) were as follows: (1) standard conditions: specific gravity - 1.98; resin content - 39.4%; barcol hardness - 67.0; flexural flatwise ultimate strength, ksi - 68.8; flexural initial modulus of elasticity, psi x 10 to the 6th power - 2.9; compression ultimate strength, edgewise, ksi - 45.0; tension ultimate strength, ksi - 40.9; (2) wet conditions: flexural flatwise ultimate strength, ksi - 50.4; flexural initial modulus of elasticity, psi x 10 to the 6th power - 2.7; compression ultimate strength, edgewise, ksi - 33.1; tension ultimate strength, kis - 38.3.
