Effect of repair parameters on composite plates under low velocity impact

Abstract: In this study, the impact behavior of patch-repaired layered composite plates was numerically investigated under low velocity impact loads. For this purpose, composite plates designed in different geometric combinations were repaired with patches using various adhesives. Impact behavior of these composites investigated by dropping the strikers with different velocities on the repaired composite plate. The laminated composite was used as the sheet and patch material, and the orientation angles were set as [0°/4… Show more

“…In another study by Tie et al [19], the effect of the off-axis angle of the patch on low-velocity impact performance was also considered, and the patch parameters were optimized using the surrogate models. Albayrak et al [20] studied the low-velocity impact response of E glass-epoxy composite plate repaired with square patches of different sizes, and large-sized patches can effectively reduce the impact force without considering the damage. The continuum damage mechanics (CDM) method based on the three-dimensional Hashin failure criterion [21,22] can effectively predict the damage of fiberreinforced composites under different modes of impact load, and together with the cohesive zone model (CZM) for predicting delamination damage, it provides a path for the simulation analysis of the impact response of CFRP laminates.…”
