对三种方法修理后复合材料蜂窝夹芯板的侧压性能进行了试验研究,结果表明,不同修理方法均可以有效恢复试件的侧压强度,所有试件侧压强度恢复率均在完好板强度的79%之上。使用k样本Anderson-Darling检验方法对试验结果进行分析,比较固化温度及固化设备等工艺因素对修理后试件力学性能的影响。结果表明:使用中温固化材料完成修理不会对修理结构的力学性能造成明显影响,同时使用热压罐完成修理区域固化通常可以改善修理后试件的力学性能,但改善程度与试件修理区域的有效高度密切相关;此外修理时要尽量避免非对称结构引起的附加弯矩对承载能力造成的不利影响。
The lateral pressure performance of composite honeycomb sandwich panels repaired by three methods was studied. The results show that different repair methods can effectively restore the lateral compressive strength of specimens, and the recovery rate of lateral compressive strength of all specimens are in good condition Above 79% of intensity. The K-sample Anderson-Darling test method was used to analyze the test results, and the influence of curing temperature and curing equipment on the mechanical properties of the repaired specimen was compared. The results show that the use of medium temperature curing materials to repair will not have obvious effect on the mechanical properties of the repaired structures. At the same time, using the autoclave to repair the area curing usually improves the mechanical properties of the repaired specimens. However, Effective and highly relevant; In addition, repair should try to avoid asymmetric structure caused by the additional bending moment on the carrying capacity of the adverse effects.
