摘　　要：通过测试不同试样规格、加载速度、测试温湿度环境等,探讨适合软木板扯断强度测试最佳条件。试验表明,试样规格和加载速度对软木板扯断强度检测结果影响显著,测试温湿度环境则影响较小,测试时应着重控制试验规格及加载速度,确保测试结果满足型号使用需求。The influence factors including sample size, loading speed, temperature and humidity of the tensile strength of the cork board were studied. The results show that the sample size and loading speed play a significant role in the tensile test. Sample size and loading speed should be carefully controlled to meet the demands of testing for the aerospace materials.
