测试程序ASTM D 3039是为测试树脂基复合材料(RMC)在室温条件下的拉伸性能而编写的。然而，当在低温下将这一过程应用于单向石墨/环氧层压板时，出现了问题。通用动力空间系统分部(GDSS)已经开发出一种可在低温下使用的替代样品设计。本文介绍了验证新标本概念的方法、分析和结果。
The test procedure ASTM D 3039 was written to generate Resin Matrix Composite (RMC) tensile properties under ambient temperature conditions. However, when this procedure was applied to unidirectional graphite/epoxy tape laminates at cryogenic temperatures problems arose. General Dynamics Space Systems Division (GDSS) has developed an alternate specimen design to be used at cryogenic temperatures. This paper explains the methodology, analysis and results to proof the new specimen concept.
