Abstract
The traditional method for analyzing the compressive strength of surface under low-speed impact damage of fiber-optic composites uses the aperture equivalent method to calculate the Compressive strength after impact (CAI) value with large error and insufficient accuracy. Aiming at the above problems, a method for calculating the CAI value of the fiber composite under low velocity impact damage by the damage accumulation method is proposed. Firstly, the materials and related equipment used in the experiment were selected, and then the initial damage state was determined by low-speed impact test. The failure state of the fiber composite under different compression loads was analyzed by compression test. Finally, the finite element model was established and the compressive strength was analyzed. The results show that compared with the open equivalent method, the calculation error of CAI value is reduced by 6.48%, the accuracy is improved, and the purpose of accurately analyzing the compressive strength is basically achieved.
