德国航宇中心开发了一种用于修理纤维增强聚合物(FRP)的新概念,旨在避免FRP零件提前报废,减少生产中的浪费。由于FRP零件复杂且昂贵,修理过程一般都费时且费钱。飞机机身中的大型结构设计寿命可达30年。如果发生损坏,通常不得不移除它们进行修理或完全更换。如果是金属结构,损坏的地方可以切除然后把新材料铆接进去。FRP制造的零件需要更复杂的修理工艺。由于纤维要承载而且使结构粘结和具有弹性,我们无法简单地原位钻孔和铆接,这只能进一步损坏纤维。相反地,DLR移除损坏的材料
The German Aerospace Center has developed a new concept for repairing fiber-reinforced polymers (FRPs) designed to avoid premature scrap of FRP parts and reduce production waste. Due to the complexity and expense of FRP parts, the repair process is generally time-consuming and costly. Large aircraft fuselage in the design life of up to 30 years. In the event of damage, it is often necessary to remove them for repair or complete replacement. If it is a metal structure, the damaged area can be cut off and the new material riveted in. Parts made of FRP require more complex repair processes. Since the fibers are to be carried and the structure is bonded and resilient, we can not simply drill and rivet in situ, which can only further damage the fibers. Conversely, the DLR removes the damaged material
