摘要

摘要: 在复合材料的结构设计中，复合材料的许用值是关键参数之一。通常采用B基准值这一统计量作为复合材料的许用值，B基准值是具有95%置信度的90%置信下限。准确计算复合材料的B基准值是复合材料安全、可靠应用的保障。本文归纳总结了复合材料B基准值计算方法的研究进展，详细分析了单点法、多环境样本合并法的计算原理、计算过程、适用条件等。结合工程实例数据，分析了不同方法对B基准值计算结果的影响。最后，对复合材料B基准值计算方法的发展趋势及预期研究方向进行了展望。

Abstract: In the structural design of composite materials, the allowable value is one of the key parameters. The statistic of B basis is usually used as the allowable value of composite materials, and the B basis is the lower limit of 90% confidence with 95% confidence. Accurate calculation of the B basis of composite materials is the guarantee for the safe and reliable application of composite materials. This article summarizes the research progress of the calculation method of the composite material’s B basis, and analyzes in detail the calculation principle, calculation process and applicable conditions of the single-point method and the pooling method. And combined with the project data, the influence of different methods on the calculation results of the B basis is analyzed. Finally, the development trend and expected research direction of the calculation method of composite material B basis are prospected.
