doi:10.3969/j.issn.1000-1093.2017.01.018

Abstract

Abstract: To solve the issues of armored vehicle's protective area reduction, relatively complex installation process and so on, which are led by those conventional installation ways like bolting or rack supporting, a novel protective armor installation technology, called bonding technology, is presented. The kind and preparation technology of bonding agent are determined by the characteristics of installing structures. An optimal glued structure design for protective armor is proposed by studying the effects of different glued joint thickness and bonding areas on bonding strength. The bonding technology for installation is proved to be feasible and reliable through the simulated car broadband vibration test and the environmental extreme temperatures suitability assessment test. For the tests mentioned above, the bonding thickness is 2~3 mm; multi-point small area is glued ; the bearing capability is more than 3 MPa shear stress per square centimeter of bonding area; the bonding strength at extreme temperature from -50 ℃ to 70 ℃ is not less than 70% of corresponding strength at normal temperature. The results show that the two-component polyurethane adhesive is able to satisfy the dynamic broadband vibration requirement. Key
