Compression-compression fatigue behavior of hybrid unidirectional/woven carbon-fiber reinforced composite laminates after low-velocity impact (LVI) was studied in this paper. The paper contains two parts. Firstly, different levels of impact energy were introduced on the specimens. Impact damage modes were obtained and characterized as fiber breakages, matrix cracks, indentation and delamination. The relationships between indentation depth/damage area and impact energy were established. Secondly, compression-compression fatigue tests were conducted on the impact damaged specimens. Fatigue life degradation trends were analyzed and fatigue limit for different types of specimens was determined. Delamination areas by depth mode and amplitude mode of C-scan showed an increasing trend with the fatigue life increasing. Stiffness decreased sharply in the early and ending stages of fatigue life. However, stiffness exhibited stable or slightly decreasing rates in the mid-stage of fatigue life. A line-shaped failure cracks going through the impact point were observed in the fatigue failure specimens.

“…Such impacts, though not as catastrophic as high-velocity ones, can still cause significant, albeit less visible, damage over time [13]. It is essential to comprehend how these composites behave when subjected to low-speed impacts in order to maintain their durability and structural soundness [14][15].…”

Glass fiber reinforced polymer (GFRP) laminates are crucial in various sectors like aerospace, navigation, automotive, wind power infrastructures because their high strength-to-weight ratio and corrosion resistance. Their susceptibility to impact damage could cause severe structural failures such as delamination, fiber rupture, and matrix fractures which are big risk for public safety. This research focuses structural behavior and failure mechanisms of GFRP laminates under low-velocity impacts to improve industry safety, reliability and performance. Impact experiments were carried out using a Split Hopkinson Pressure Bar (SHPB) on panels configured in various fiber orientations, specifically [(0/90)s, (+45/-45)s, and (0/90/+45/-45)s]. Force-time history and impactor velocity, were captured and analyzed to assess the material's resilience and mechanical properties are main key experiments aspects. The purpose of the study to experimental and numerical approach to explore how GFRP laminates react to low-velocity impacts using a Split Hopkinson Pressure Bar (SHPB). Panels in various fiber orientations were tested with impact energies ranging from 1 J to 10 J by using advanced modeling techniques such as progressive damage mechanics, cohesive zone models, and virtual crack closure were implemented in the ABAQUS/Explicit framework to assess internal damages.

This paper investigated the effect of stacking sequence on the low velocity impact behavior of glass and jute fiber reinforced hybrid composites. The hand layup method is used to fabricate the composites with various stacking sequences. The low velocity impact analysis was carried out at various impact energies, namely 5 J, 10 J and 15 J. Dye penetrant inspection (liquid penetrate inspection) was performed to analyses the damage area in the composites. Compression after impact (CAI) testing was conducted to study the compression strength of the composites after the impact. The study revealed that the jute fiber composites exhibited better results in terms of energy absorption, but the damage area of the composites was higher, compared to the other specimens fabricated. Meanwhile, hybrid composite S7 presented high energy absorption and the minimum damage area. To conclude, the hybrid composite S7 appeared to have the optimum formulation, showing better results in energy absorption, with lower damage and higher compression strength.
