摘要

摘要在这项工作中，通过高压釜工艺获得的碳-环氧复合材料在温度、水和紫外线辐射受控条件下进行了加速老化。每种复合材料在 60°C 的盐水或 60°C 的紫外线辐射下暴露 6 个月。通过质量和密度变化、机械测试以及伪装效果，对复合材料内部的变化进行了评估。结果显示，质量损失或密度变化不大，机械性能略有下降。最大的变化是伪装。据观察，在加速老化过程中，复合材料的再发射系数变得过高，复合材料失去了伪装特性。

Investigation of the Accelerated Ageing of Carbon-Epoxy Composites on their Mechanical Properties

Abstract In this work, carbon-epoxy composites obtained by an autoclave process were subjected to accelerated ageing in controlled conditions of temperature, water and UV radiation. Each composite was exposed to salt water at 60°C or UV radiation at 60°C over a period of 6 months. Changes within the composites were evaluated by mass and density variation, mechanical testing and also in terms of camouflage. Results did not show significant changes in mass loss or density, and it was found that mechanical properties had decreased slightly. The biggest change is in camouflage. It was observed that during accelerated ageing, the composites’ reemission coefficient becomes too high and composites lose camouflage properties.
