Microscopic Analysis of Compression Response of Carbon Fiber Composites

  • 摘要: 设计了实验平台,对纤维压缩应变与电阻间灵敏系数进行了标定,将标定后的纤维制作成单丝和多丝复合材料体系压缩试验件。在压缩载荷条件下,通过电阻测量,揭示了多丝复合材料体系纤维断裂对周围纤维的影响规律,并准确测量出纤维发生压缩破坏时的最大变形量;利用数值方法模拟了断口处基体应力分布导致附近纤维微屈曲的损伤过程。
    Abstract: An experimental platform was designed, and the sensitivity coefficient between the fiber compression strain and the resistance calibrated. The calibrated fibers are made into single-filament and multi-filament composite material system compression test specimens. Under the compressive load conditions, the influence of fiber fracture of multi-filament composite material specimen on surrounding fibers was investigated, and the maximum deformation of the fiber at the fracture was measured accurately. On the above basis, numerical methods were adopted to simulate the damage process of the micro-buckling of fibers around the fracture caused by the stress distribution of the matrix.
