精细陶瓷（先进陶瓷 先进技术陶瓷） - 环境温度下连续纤维增强陶瓷复合管的箍拉伸性能

[中文适用范围]： 本文件规定了在环境温度和大气压下测定连续纤维增强陶瓷基复合材料（CMC）管环向拉伸性能的条件。 本文件特定于管状几何形状，因为复合管中的纤维结构和样本几何形状因素与扁平样本中的明显不同。 本文件提供了有关环向拉伸特性和应力应变响应的信息，例如环向拉伸强度、失效时环向拉伸应变和弹性常数。 这些信息可用于管状部件的材料开发、制造控制（质量保证）、材料比较、表征、可靠性和设计数据生成。 本文件涉及但不限于各种建议的测试件制造方法。 它主要适用于具有连续纤维增强的陶瓷和/或玻璃基复合管：单向（1D 纤维缠绕和带铺层）、双向（2D 编织和编织）和三向（xD，2 < x < 3)，受到内部压力。 本文件中表达的值符合国际单位制 (SI)。 [外文原描述]： This document specifies the conditions for the determination of hoop tensile properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at ambient temperature in air atmospheric pressure. This document is specific to the tubular geometries since fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This document provides information on the hoop tensile properties and stress-strain response, such as hoop tensile strength, hoop tensile strain at failure and elastic constants. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components. This document addresses, but is not restricted to, various suggested test piece fabrication methods. It applies primarily to ceramic and/or glass matrix composite tubes with a continuous fibrous-reinforcement: unidirectional (1D filament winding and tape lay-up), bi-directional (2D braid and weave) and tri-directional ( x D, with 2 < x < 3), subjected to an internal pressure. Values expressed in this document are in accordance with the International System of Units (SI).
