摘要

本研究旨在探讨采用各种典型固化工艺制成的碳纤维复合材料产品的抗渗漏性。首先，测量了不同固化方法生产的试样的泄漏率，并对缺陷进行了统计分析。然后，应用模拟方法从孔隙率、空隙分布和空隙形态三个因素数值研究了这些缺陷特征对泄漏率的影响，并制备了带有预制缺陷的试样，测试了其泄漏性能以验证模拟结果。最后，从固化缺陷的角度分析了不同固化工艺下试样抗渗漏性的差异，并确定了有助于提高抗渗漏性的具体缺陷特征。

Investigations on the leak resistance performance and the difference mechanism of composite materials under several typical curing processes

This study aims to investigate the leak resistance of carbon fiber composite products formed by various typical curing processes. Firstly, the leak rates of specimens produced through different curing methods were measured, and the defect were statistically analyzed. After that, the simulation approach was applied to numerically study the impact of these defect characteristics on leak rates was examined from the three factors of porosity, void distribution and void morphology, specimen with prefabricated defects was prepared, and its leak performance were tested to validate the simulation results. Finally, the differences in leak resistance among specimens under different curing processes were analyzed from the perspective of curing defects, and specific defect characteristics contributing to enhanced leak resistance were identified.
