“…Studies have shown that laminated composite structures are even more at perils to impact-related damage than steel structures [14]. In most studies, scholars have focused on the effects of varying parameters, fibre architecture, and thickness of the composites [15,16]. However, fewer studies have been performed concerning the influence of moisture exposure and elevated temperatures on the residual strength of natural/synthetic fibre hybrid composites under low-velocity impact event.…”

“…In a study performed by Cheng et al, the low‐velocity impact performance of scarf‐repaired composite laminates was investigated by experimental and numerical methods. It was analyzed and showed the effects of the scarf angle, the adhesive thickness, and the patch off‐axis on the impact properties.…”

Low‐velocity impact performance of notched glass fiber reinforced plastic composites repaired by bonding external composite patches was investigated by experimental and numerical methods. Various patches of different fiber materials such as carbon and glass fiber and thickness were considered under different impact energy levels. The continuum damage mechanics based on a dynamic progressive damage model was using to build the finite element model and cohesive elements were used between the composite patch and notched composite plate. Five different failure criteria based on three‐dimensional Hashin damage models were implemented by the explicit finite element subroutine ABAQUS‐VUMAT with degradation model and used to compare experimental damage areas. The experimental contact force, kinetic energy histories, and experimental damage areas were calculated and compared the numerical ones. While the experimental data confirm the efficiency of the proposed model, they show consistent results with the numerical model. Finally, using the composite patch is succeeded to avoid impact damage. This research provides fundamental support for the appropriate selection of external composite patch type and use of the degradation model with different failure model to achieve high‐efficiency simulation under impact loading.

“…Lightning strike, foreign object damage during maintenance, and hailstone strike are a few incidences of impact load that interact with composites. These incidents cause the matrix crack, fiber breakage, fiber splitting, delamination, and de-bonding, which has led to the failure of composite laminates [8,10,11,12,13,14,15].…”

The effect of multiple/repeated impacts on a repaired composite was investigated using a low-velocity impact test. The composite samples were fabricated through a vacuum resin infusion method (VARI) and repaired by a scarf repair technique. Later, a repeated low-velocity impact test was performed on the original and repaired composites samples. Performance of the multi-impacted repaired and original samples was evaluated and compared by measuring maximum contact force, maximum displacement, maximum time duration, absorbed energy and damage area. Photographs of the post-impacted samples were taken to observe the multi-impact damage progression through visual inspection. The results showed that each repeated impact subjected the samples to more damage. Tensile tests revealed that the scarf repair restored 81.23% strength. It was also observed that the sample obtained the highest damage dent in the low-velocity impact test that failed early during a tensile test and carried the lowest ultimate load.
