4 斜接修补模型我们研究斜接修补的对称复合材料层板(图16)。当这样修补的层板受拉伸荷载时此层板可能拉坏、修补贴片可能拉坏、隔层可能剪坏、当隔层剪坏的同时层板可能拉坏、以及当隔层剪坏的同时修补贴片可能拉坏(图17)。计算发生每种这类破坏荷载的方法如下。
4 Miter patching model We studied a miter patched symmetrical composite laminate (Figure 16). When such a repaired laminate is subjected to tensile loading, the laminate may pull out, the patch may pull out, the spacer may become damaged, the laminate may pull out while the spacer is broken, and when the spacer is damaged At the same time repair patches may pull bad (Figure 17). The method of calculating each such destructive load is as follows.
