| 中文摘要: |
| 目的 针对吸波结构的基体材料——一种软质聚氨酯泡沫耐老化性能的考核，设计一种环境适应性试验，确定施加的环境应力和产品老化性能的表征参数。方法 通过吸波结构的聚氨酯泡沫材料的特征性能参数分析，根据产品应用要求和预试验结果，确定合适的老化性能的主要表征指标，通过多应力水平试验和方差分析，确定采用的主要加速老化环境应力。结果 通过预试验与分析认为，吸波结构用聚氨酯泡沫材料耐老化性能可采用断裂伸长率来作表征，由于防水覆膜能很好地阻隔水汽对聚氨酯材料的影响，采用单温度应力便可以来考核其老化性能。结论 针对具有防水覆膜的吸波结构用聚氨酯泡沫材料，采用单温度应力作用下的断裂伸长率变化可以对其耐老化性能进行有效评估。 |

| The paper aims to design an environmental worthiness test to determine the applied environmental stress and characterization parameters of aging properties of the polyurethane foam matrix to evaluate the aging resistance of polyurethane foam matrix used to absorb electromagnetic wave structure.Through the analysis on property parameters of the polyurethane foam matrix, combined with application requirements and pre-test results of product, the appropriate aging performance characterization index was determined. Through variance analysis of aging test results under various environmental stress conditions, the main accelerated aging environmental stress was determined. According to the pre-test and analysis, the aging resistance of polyurethane foam matrix can be characterized by elongation at break. Because waterproof film can well block the influence of water vapor on polyurethane foam matrix, the aging performance can be assessed by applying single temperature stress. For polyurethane foam matrix used for absorbing structure with waterproof coating, the change of elongation at break under single temperature stress can effectively evaluate its aging resistance. |
