Production product made by th
41、e revised procedure shall not be shipped prior to receipt of reapproval.4.5 Test Methods: Shall be as follows: properties of cured product shall be determined on test laminates prepared as in 4.5.1:4.5.1 Preparation of Test Laminates: Test laminates of suitable area shall be prepared from sufficient
42、 plies of impregnated cloth oriented unidirectionally to produce cured thicknesses as close as possible to 0.030 inch (0.76 mm) for tensile strength and modulus of elasticity and as close as possible to 0.125 inch (3.18 mm) for all other tests of cured product. Laminates shall be cured at a temperat
43、ure and pressure which will provide optimum properties; the temperature and pressure used shall be noted in the report. The resulting laminates shall each be uniform in thickness within 0.003 inch (0.08 mm).4.5.2 Tack: 4.5.2.1 Cut two pieces of impregnated glass cloth approximately 1 x 3 inches (25
44、x 76 mm), retaining the protective film until immediately before using the specimens. Fiber direction shall be parallel to the 1-inch (25-mm) dimension. For cloth under 3 inches (76 mm) wide, butt sufficient pieces on the panel to produce a 3-inch (76-mm) wide specimen.4.5.2.2 Remove the protective
45、film from one side of one specimen and apply the cloth to the center of a clean piece of austenitic corrosion resistant steel sheet with a commercial 2D finish, any thickness by approximately 4 x 8 inches (102 x 203 mm). Apply light pressure with a squeegee or roller over the backing film. Remove th
46、e backing film and apply the second specimen to the first, in exactly the same manner, making certain that the opposing faces of the cloth are not covered with protective backing film. The second layer of narrow cloth shall be so positioned that the butt joints do not coincide with those of the firs
47、t layer. Remove the protective film from the exposed surface of the cloth and maintain the test plate and the long dimension of the test specimen in a vertical position for not less than 30 minutes at 20 to 30 C (68 to 86 F) and 50 to 70% relative humidity.4.5.2.3 Report results as pass or fail.
