摘要

In this study, an integrated composite antenna structure was designed and fabricated to investigate its behavior under low-velocity impacts with energy levels ranging from 10 J to 100 J. The specimens were positioned and supported in accordance with ASTM D7136 standards, while post-impact compression tests followed ASTM D7137 protocols. Numerical models were developed using ABAQUS finite element (FE) software to validate experimental results, including impact response curves, damage morphologies, and compression failure modes. Both experimental and simulation results demonstrated strong agreement, confirming the accuracy of the constitutive model. Additionally, electromagnetic performance evaluations through experiments and simulations verified the structural integrity and functional reliability of the antenna under varying impact conditions.
