介绍一种评估飞机结构防护涂层老化的方法—当量法。这种方法利用涂层大气幕寡试验和加速试验数据,建立统一的老化模型,从而确定涂层自然老化与加速试验老化的当量关系,并且给出了涂层老化当量关系的计算结果,进而得到了涂层使用寿命。通过试验结果与计算结果的比较所建立的老化模型描述飞机结构涂层老化是合适的。现已用于评估某飞机涂层的老化。
A method to evaluate the aging of protective coating of aircraft structure - equivalent method is introduced. In this method, a uniform aging model is established by using the data of the coating air curtain oligomerization test and the accelerated test to determine the equivalent relationship between the natural aging of the coating and the accelerated aging test, and the calculation result of the aging equivalent of the coating is obtained. The coating life. The aging model established by comparing the test results with the calculated results describes that the aging of the aircraft structure coating is suitable. Now used to assess the aging of a plane coating.
