NUCAP is a privately owned company with its headquarter in Ontario. It has developed a patented GRIP MetalTM technology to generate a series of hooks on metal surface in order to enhance bonding strength between metal and adhesives. The company wishes to expand its business into light weight fibre metal laminates (FML) for aerospace applications. However, the damage tolerance of the bonded structure with GRIP MetalTM under cyclic loading is unknown and numerous GRIP MetalTM configurations require a way to assess the fatigue behavior in a batch manner. This research is proposed to examine the presence of cracks and crack propagation in aluminum GRIP MetalTM and bonding behavior of GRIP MetalTM sandwiched structure after cyclic loading while at the same time develop a batch fatigue test method so that sandwiched structure with various hook configurations can be assessed in simultaneously

Nucap是一家私人公司，其总部位于安大略省。它开发了一项专利的Grip Metaltm技术，可以在金属表面上产生一系列钩子，以增强金属和粘合剂之间的键合强度。该公司希望将其业务扩展到用于航空航天应用的轻质纤维金属层压板（FML）。但是，在环状载荷下使用Grip MetalTM键合结构的损伤耐受性尚不清楚，并且许多Grip MetalTM配置需要一种以批量方式评估疲劳行为的方法。提出了这项研究，以检查铝抓地金属TM中的裂纹和裂纹繁殖的存在以及循环载荷后夹心金属TM夹层结构的粘结行为，同时开发出批处理疲劳测试方法，以便可以评估具有各种挂钩构型的夹层结构同时
