摘要/Abstract

摘要： 对复合材料层压板胶接挖补修理后强度特性分析及评估方法开展了研究,提出了一种能够模拟复合材料挖补修理结构逐渐失效过程以及强度预测的数值分析方法;设计并完成了无损试样及楔形挖补修理试样的拉伸试验,以验证计算模型的有效性及精度;最后,利用提出的数值分析模型,进行了复合材料挖补修理参数影响分析,发现5°为最优挖补修理角,胶层厚度以0.1 mm为宜。当补片铺层中0°和±45°层各占50%时,挖补修理层合板承载能力最高。

Abstract: The strength characteristics analysis and evaluation method of composite laminates after repair and repair by bonding were studied, and a numerical analysis method was proposed to simulate the gradual failure process and strength prediction of composite repair and repair structures. The tensile tests of non-destructive specimens and wedge repair specimens were designed and completed to verify the validity and accuracy of the calculation model. Finally, using the proposed numerical analysis model, the influence analysis of composite material repair parameters is carried out. It is found that 5° is the optimal repair angle, and the thickness of the adhesive layer is 0.1 mm. When the 0° and ±45° layers in the patch layer account for 50% respectively, the repair laminate has the highest bearing capacity.
