Abstract

The possibility of applying the method of ultrajet diagnostics for estimation of the stress–strain state (SSS) of carbon-fiber samples is considered. It was shown as a result of a series of experiments and numeric computations that informative parameters of the cavern do not contain objective information about the state of material in the current load state. This may be useful for the construction of a general method for diagnosing samples made of carbon fiber for estimation of their operational life, including the conditions of the effect of a set of external factors: static loading, temperature, various types of electromagnetic radiation, et al. Experiments showed there to be high indicators of correlation between computed values of stresses and depths of caverns formed as a result of ultrajet impact on the surface of carbon-fiber samples.

复合材料超射流诊断方法扩展潜力的估计

摘要

考虑了应用 Ultrajet 诊断方法来估计碳纤维样品的应力应变状态 (SSS) 的可能性。一系列实验和数值计算的结果表明,洞穴的信息参数不包含有关当前负载状态下材料状态的客观信息。这对于构建用于诊断由碳纤维制成的样品以估计其使用寿命的通用方法可能很有用,包括一组外部因素的影响条件:静态负载、温度、各种类型的电磁辐射等阿尔。实验表明,由于超喷流冲击碳纤维样品表面而形成的洞穴深度与应力计算值之间存在高度相关性。
