Abstract:

Parallel laminated panels 0.115 inch thick fabricated with 12 plies of fiberglass cloth No. 181, Volan A were impregnated with Type F.C.R. polyester resin and cured at 190 F for two hours under 10 to 12 psi vacuum bag pressure. Qualification test outcomes were as follows 1 standard conditions specific gravity - 2.21, resin content - 59, barcol hardness - 62.0, flexural flatwise ultimate strength, ksi - 68.8, flexural initial modulus of elasticity, psi x 10 to the 6th power - 2.8, compression ultimate strength edgewise, ksi - 44.0, tensile ultimate strength, ksi - 40.8, and 2 wet conditions flexural flatwise ultimate strength, ksi - 61.5, flexural initial modulus of elasticity, psi x 10 to the 6th power - 2.8, compression ultimate strength edgewise, ksi - 39.5, tensile ultimate strength, ksi 39.6.
