随着粘接修理技术逐渐被认可和日趋标准化,汉莎技术公司认为,复合材料主要结构的金属螺接修理或将成为过去。目前,主要结构中目视损伤唯一许可的修理方法是螺接修理,即在标准的金属飞机上用螺栓打了一块补丁。复合材料采用螺接修理可能是有害的,因为它会使复合材料结构的残余强度降低50%以上,而且会增加额外的重量。现在,汉莎技术公司已经逐渐开始针对复合材料主要结构采用粘接修理。 As adhesive repair technology is gaining acceptance and becoming more standardized, Lufthansa Technik believes that the repair of the metal-bolted composite structures will become a thing of the past. Currently, the only method of repair for visual impairment in the main structure is bolting, where a patch is bolted to a standard metal plane. Repairing a composite with a screw may be detrimental because it reduces the residual strength of the composite structure by more than 50% and adds extra weight. Now, Lufthansa Technik has gradually started to apply adhesive repair to the main structure of the composite material.
