30、t: Cut three specimens each 72 inches 0.1 (1829 mm 2.5) long. Fold each specimen three times to a length of approximately 9 inches (229 mm) and tie loosely into an overhand bow knot. Weigh each specimen to the nearest 0.001 gram. Hang each specimen separately on a rack and place in an oven at 135 C

31、3 (275 F 5) for 15 minutes 1. Cool to room temperature in a desiccator and weigh each specimen. Calculate volatile using Equation 1.(Eq. 1)where:W 0 = original weightW 1 = final weightAverage the results from the three specimens.4.5.2 Gel Time: Precondition a suitable melting point apparatus to 165

32、C 1 (329 F 2). Place a microscope slide on the heated block, allowing 20 to 30 seconds for it to reach temperature equilibrium. Cut a piece of roving 1/4 inch 1/16 (6.4 mm 1.6) long. Place sample on a heated microscope slide and commence timing. Within five seconds, place a second microscope slide o

33、ver the sample. As the resin softens and during the first 30 seconds, isolate a drop of resin by gently pressing on the upper slide. Observe lateral movement of the resin drop while periodically pressing on the upper slide. As the resin thickens, the lateral movement will be retarded. A sharp color

34、change and the formation of small droplets when the cover slide is pressed indicate the gel point. Stop the timer and record the elapsed time in minutes as gel time. Report the average of three results.4.5.3 Resin Flow: Cut six lengths of roving, each 3 inches (76 mm) long. Weigh each specimen, cons

35、isting of two 3-inch (76-mm) lengths, to the nearest 0.001 gram. With the lengths spaced 1/2 inch (12.7 mm) apart, sandwich the specimen between four layers (two on each side of specimen) of MIL-C-9084, Type I, Volan A finish glass cloth. Preheat a 1500-gram metal weight to 150 C 5 (302 F 9). Press

36、the sandwiched material on a preheated hot plate and maintain at 150 C 5 (302 F 9) for two minutes, using a surface pyrometer to ensure maintenance of the required temperature. While still hot, remove the glass cloth and reweigh each roving specimen to the nearest 0.001 gram. Calculate resin flow us
