Influence of Cure Environment and Cure Temperature on Failure Properties of Acetylene Terminated Sulfone
Abstract
Air cure effects on the tensile and fracture behavior are studied with an acetylene terminated sulfone resin. It is found that in all instances, the air cure improves the mechanical properties. As much as 30% improvement can be attained depending on the extent of cure performed in the presence of air. The amount of improvement appears to depend on the thickness of the test specimens. Density measurements show different values for the air cure and the nitrogen cure specimens. Similar thickness dependency on the total air effect is also observed. The air effect is also affected by the stage of cure when the air is introduced. The effect is larger when air is introduced early in the cure. The results are consistent with the dynamic mechanical data and show the role of air diffusing into the sample in controlling the total improvement in mechanical properties. Tensile properties at different extents of cure are also measured. Those data indicated that at the initial cure stages, the mechanical properties of the resin are poor. Thus damage could be sustained by parts during the processing procedure if they were not handled properly at these stages.
