| 目的 选用复合材料用耐环境涂层体系的最优厚度使用比例，提高复合材料的综合力学性能和耐湿热性。方法 针对复合材料用底漆/面漆涂层体系，通过控制喷涂工艺将涂层的厚度控制转化为层数控制，设计4组不同层数的底漆/面漆涂层，对单层和多层复合材料用抗腐蚀涂层体系的柔韧性、附着力、冲击性能以及耐湿热性能进行了系统表征。结果 随着涂层厚度的增加，涂层体系的柔韧性、附着力、耐冲击性能均有所降低。涂层通过隔绝水环境与复合材料的直接接触，有效降低了吸湿速率，具有较好的湿热防护性能，随着涂层厚度的增加，耐湿热性提高。涂层体系的柔韧性、附着力、耐冲击性能以及耐环境性能与厚度之间并非简单的线性关系。结论 通过控制涂层单层厚度将厚度优化转变为层数优化，提出了一种有机涂层厚度优化的试验方案，并确定(1×2)厚度设计下涂层兼具较优的力学性能和耐湿热性能。 |

| The work aims to improve the comprehensive mechanical properties and hygrothermal properties of composite materials by using the optimum thickness ratio of environmental coating system for composite materials. For composite primer/topcoat system, thickness control of coating was transformed to layer control by controlling the spraying process and 4 groups of primer/topcoat in different layers were designed. Flexibility, adhesion, impact resistance and hygrothermal properties of anticorrosion coating system were used to systematically characterize he single-layer and multi-layer composite materials. As the coating thickness increased, flexibility, adhesion and impact resistance of coating system decreased; the coating could effectively reduce the heat absorption rate and provided better heat and humidity resistance by isolating the direct contact between water and composite materials, and as the coating thickness increased, the heat and humidity resistance increased. The relation between flexibility, adhesion, impact resistance and environmental resistance of coating system and the coating thickness was not just linear. A test scheme on thickness optimization of organic coating is put forward by controlling the thickness of single-layer coating to transform the thickness optimization into the layer optimization and better mechanical properties and hygrothermal properties of coating under the design of (1´2) thickness are determined. |
