【摘要】 平拉强度测试标准是检验复合材料夹层结构产品质量的主要方法之一,近年来,受到了越来越多科研人员的关注。本文从标准结构与内容两个方面,对GB/T 1452-2018和GB/T 1452-2005的主要变化、GB/T 1452-2018和ASTM C297/297M-16的主要差异进行了比较分析。结果表明,相比于GB/T 1452-2005和ASTM C297/297M-16,GB/T 1452-2018结合我国实际情况对相关章节作出了许多适用的新规定,是一个明显的进步,已经达到了国际先进测试标准水平。更多还原

【Abstract】 The standard for flatwise tensile strength is one of the main methods for testing the quality of composite sandwich constructions. In recent years, it has attracted the attention of more and more researchers. In this paper, the main differences between GB/T 1452-2005, GB/T 1452-2018 and ASTM C297/297 M-16 are compared and analyzed in terms of standard structure and content. The results show that compared with GB/T 1452-2005 and ASTM C297/297 M-16, GB/T 1452-2018 contains many applicable new regulations given the actual situation in China, which is an obvious progress; the standard has reached the level of international advanced testing standards.更多还原
