Present work aimed to investigate the hybridization effect of Kevlar and glass fibers to enhance the impact performance of CFRP composites under low velocity by numerical analysis. Analyzing the stack sequencing of Kevlar and glass fibers becomes essential to improve the impact resistance of CFRP composite structures. It is important to know the dynamic behavior of hybrid composites under LVI. To get the best possible stack sequence, numerical simulations were carried out on different stacking sequence combinations of Kevlar and glass with carbon fiber epoxy composites for 25 J energy levels. A virtual drop weight impact test conditioned numerical model created in Abaqus software mimics the actual intralaminar and interlaminar failure. Intralaminar models based on continuum damage mechanics and interlaminar, that is, delamination failure based on cohesive modeling used to evaluate the damage development and material behavior. From the obtained simulation results, the hybrid composites having Kevlar fibers exhibited superior impact resistance.

The boundary condition is a very important factor when characterizing the impact performance of a material or a structure. However, its effect on fiber metal laminate (FML) has been rarely mentioned. In the present investigation, three levels of low‐velocity impact tests were conducted on the glass fiber reinforced aluminum laminate (Glare) under two different boundary conditions, one was that defined in ASTM D7136 and another one was self‐designed that has the same constraint area but different constraint degree. One basis of the experiments, finite element analyses were performed to gain a deeper understanding of the different damage mechanisms. With which another three boundary conditions were investigated for further considering the effect of constraint areas on both the impact and non‐impact sides, including that defined in another commonly used standard ASTM D5628 and two self‐designed cases. It was indicated that the boundary conditions influenced less the force and energy responses of Glare laminate, regardless of the impact damage levels, and hardly on the damage behavior as well when perforation was encountered. However, influences were obtained under lower and intermediate damage levels, and it was the constraint area on the rear side and constraint degree that played the dominant roles, respectively. The results achieved can provide suggestions for reasonably evaluating the low‐velocity impact performance of FML.Highlights Comparisons were made between the low‐velocity impact behavior of Glare laminates under five different boundary conditions. Boundary conditions influenced hardly on maximum impact force and energy absorbed ratio, but evidently on damage behavior. Constraint area and constraint degree governed damage mechanism under lower and intermediate impact energies, respectively. Influence of boundary conditions on damage behavior disappeared when the impact energy was enough to perforate Glare laminate.

The tuning of the structural batteries for various applications of transportation is an ambitious target. The pollutant emission and mostly the process for battery recycling and recovery are peculiar aspects to consider for new designs. The goal is to reduce the weight. In this frame, taking into account that the traditional battery packs do not contribute to the structural performance, it is worth to underline the solution of the structural batteries allows to increase the mechanical properties as they are integrated into the primary structure. The paper establishes the response of a composite structural battery model subjected to low-velocity impact tests. The process used to manufacture the structural battery model is described, and the experimental activities are performed by a customized drop tower and finally replicated numerically by explicit code to enhance the comprehension of the structural dynamics. Differences with respect to a carbon fiber laminate are highlighted both for the force released at the impact and dart displacement, for the same levels of energy.
