当飞机变旧时,座舱增压循环会导致紧固件和风挡周围产生裂纹。常规裂纹修补方法劳动强度较大,耗费时间较多。此外,还要求能够处理一系列与修补有关的维护问题。目前,由美国空军资助开发的硼—环氧复合材料修补技术已能成功地解决这些问题。 复合材料补片的安装比较简单。首先,按飞机制造商批准的方法制备待修补的表面;然后,放上热固性薄膜胶 When the aircraft gets older, cockpit pressurization cycles can cause cracks around fasteners and windshields. Routine crack repair methods labor-intensive, more time-consuming. In addition, it is also required to be able to handle a series of repair-related maintenance issues. Currently, the boron-epoxy composite repair technology developed by the U.S. Air Force has successfully addressed these issues. Composite patch installation is relatively simple. First, prepare the surface to be repaired as approved by the aircraft manufacturer; then place a thermosetting film adhesive
