精细陶瓷（先进陶瓷 先进技术陶瓷） 高温下陶瓷复合材料的力学性能 管材轴向拉伸性能的测定

[中文适用范围]： 本文件规定了在空气、真空和惰性气体气氛中高温下测定连续纤维增强陶瓷基复合材料（CMC）管轴向拉伸性能的条件。本文件的适用性专门针对管状几何形状，因为复合管中的纤维结构和试样几何因素与扁平试样明显不同。本文件提供了高温下轴向拉伸性能和应力-应变响应的信息，例如轴向拉伸强度、破坏时的轴向拉伸应变和弹性常数。该信息可用于材料开发、制造控制（质量保证）、材料比较、表征、可靠性以及管状部件的设计数据生成。本文件涉及但不限于各种建议的试件制造方法。本文件主要适用于具有连续纤维增强的陶瓷基复合管：单向（1D，纤维缠绕和带材铺设）、双向（2D，编织和机织）和多向（xD，x>2），沿管轴进行测试。 [外文原描述]： This document specifies the conditions for determination of the axial tensile properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at elevated temperature in air, vacuum and inert gas atmospheres. The applicability of this document is specific to tubular geometries because fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This document provides information on the axial tensile properties and stress-strain response in temperature, such as axial tensile strength, axial 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. This document is primarily applicable to ceramic matrix composite tubes with a continuous fibrous-reinforcement: unidirectional (1D, filament winding and tape lay-up), bi-directional (2D, braid and weave) and multi-directional ( x D, with x > 2), tested along the tube axis.
