34、men Preparation: Cut three specimens, each 72 inches 0.1(1829 mm 3) long. Fold each specimen three times to a length ofapproximately 9 inches (229 mm) and tie loosely into an overhand bowknot.Volatile Content: Weigh each specimen to the nearest 0.001 gram (W,).Hang pieces separately on a rack and pl

35、ace in a circulating-air oven at135 C 3 C (275 F 5) for 15 minutes 1, cool to room temperaturein a desiccator, and reweigh each specimen (W2).

Place a microscope slide on the heat

39、ed block, allowing20 to 30 seconds for it to reach temperature equilibrium. Cut a piece ofroving l/4 inch l/16 (6.4 mm t 1.6) long. Place a sample on the heatedmicroscope slide and commence timing. Within five seconds, place a secondmicroscope slide over the sample. As the resin softens and-during t

40、hefirst 30 seconds, isolate a drop of resin by gently pressing on the upperslide. Observe lateral movement of the resin drop while periodicallypressing on the upper slide. As the resin thickens, the lateral movementwill be retarded. A sharp color change and the formation of small dropletswhen the co

Report the average of three results.4.5.3 Resin Flow: Cut six lengths of roving, each 3 inches 0.010(76 mm 0.25) long. Weigh each specimen, consisting of two 3 inch(76 mm) lengths to the nearest 0.001

42、 gram (W1). With the lengths spacedl/2 inch (12.7 mm) apart, sandwich the specimens between four layers (twoon each side of the specimen.) of ASTM D 2410-82, type 181 to 150 or type181 to 75G, glass cloth. Preheat a hot plate and a 1500-gram metal weightto 150 C 5 (302 F 9). Place the sandwiched mat

43、erial on the hotplate, cover with the metal weight, and maintain at temperature for2 minutes 0.2 using a surface thermocouple to ensure maintenance of therequired temperature. While still hot, remove the specimens from thesandwich, remove any excess resin, and cool in desiccator to roomtemperature.

44、Reweigh each specimen to the nearest 0.001 gram (W1).Calculate resin flow using Equation 3.Resin Flow, wt% =W1 - W2x 100W1(Eq.3)where:W1 = weight of specimen before heatingW2 = weight of specimen after removal of excess resin4.6 Reports:Supplier of roving shall furnish with each shipment a report sh
