本文采用活性涂层、刚性涂层、柔性涂层分别对 F－ 12纤维进行表面处理，并研究了不同涂层对 F－ 12/AE4环氧 NOL环复合材料剪切强度的影响。试验结果表明，各种涂层对其复合材料的剪切性能都有一定的影响。其中，刚性涂层有利于提高 NOL环的剪切强度。
In this paper, F-12 fibers were treated with active coating, rigid coating and flexible coating, respectively. The effects of different coatings on the shear strength of F-12 / AE4 epoxy NOL composite were investigated. The experimental results show that all kinds of coatings have certain influence on the shear properties of the composites. Among them, the rigid coating is conducive to improving the shear strength of NOL ring.
