摘　　要：拉伸断裂强力作为碳纤维机织物质量控制的一项重要指标,其测试方法尚无相应的国家标准。从标准内容及操作层面,结合现有的研究成果,对行业内使用的两个典型测试标准——GB/T7689.5—2013和GJB 2370A—2017附录A进行了比较,旨在分析和探讨测试方法的可行性。对比发现,GB/T 7689.5—2013的制样方法和预加张力对碳纤维机织物的适用性不强。GJB 2370A—2017的测试方法适用性和可操作性都非常好,但在碳纤维机织物行业内的普及性不高。因此,碳纤维机织物行业迫切需要制定统一的、通用的检测方法标准及产品接收标准。As an important performance index of quality control for carbon fiber woven fabric,tensile strength still has no its national test standard.From the standard content and operation level,combined with the existing research results,two typical test standards used in the industry—GB/T 7689.5—2013 and GJB2370A—2017 appendix A were compared,aiming at analyzing and discussing the feasibility of the test methods.It is found that the sample preparation method and pretension of GB/T 7689.5—2013 are not suitable for carbon fiber woven fabrics.The test method of GJB 2370A—2017 is very good in applicability and operability,but the popularity of carbon fiber woven fabric industry is not high.Therefore,carbon fiber woven fabric industry urgently needs to develop a unified,universal testing method standards and product acceptance standards.
