本文给出了两个三维四向整体编织碳 /环氧复合材料圆锥壳体临界外压的试验结果 ,进一步验证了三维四向整体编织复合材料壳体临界外压计算方法。计算结果与试验结果相符较好 ,计算时试验修正系数可取 0 .8。
In this paper, the experimental results of the critical external pressure of two three-dimensional four-way braided carbon / epoxy composites conical shells are given, which further validates the calculation of the critical external pressure of the three-dimensional four-direction braided composite shell. The calculation results are in good agreement with the test results, and the test correction coefficient should be 0.8 when calculating.
