“…However, the maximum damage length “secondary failures” are quite considerable for the carbon/Epoxy experimental case. Carbon/Epoxy’s relatively small main damage area may be explained by its fragile failure characteristics, since damage tends to be more localized, similarly to the expected result in a high energy ballistic test [ 18 , 70 ].…”

“…In these tests, a flat, rectangular composite coupon plate is subjected to an out-of-plane, concentrated impact load using a drop-weight device with a hemispherical impactor. The drop-weight potential energy is defined by the specified mass and drop height of the impactor [ 16 , 17 , 18 , 19 ]. Information obtained from computer models and experimental results on the coupon-scale analysis can be then used to investigate the behavior of the full-scale component ( Figure 1 ).…”

Damage generated due to low velocity impact in composite plates was evaluated focusing on the design and structural integrity of wind turbine blades. Impact properties of composite plates manufactured with thermoplastic and thermoset resins for different energy levels were measured and compared. Specimens were fabricated using VARTM (vacuum assisted resin transfer molding), using both matrix systems in conjunction with carbon, glass and carbon/glass hybrid fibers in the NCF (non-crimp fabric) architecture. Resin systems used were ELIUM 188O (thermoplastic) from Arkema Co., Ltd. and a standard epoxy reference, EPR-L20 from Hexion Co., Ltd. (thermoset). Auxiliary numerical finite element analyses were performed to better understand the tests physics. These models were then compared with the experimental results to verify their predictive capacity, given the intrinsic limitations due to their simplicity. Based in the presented results, it is possible to observe that ELIUM is capable to replace a conventional thermoset matrix. The thermoplastic panels presented similar results compared to its thermoset counterparts, with even a trend of less impact damage. Additionally, for both thermoplastic and thermoset resin systems, glass layups showed the lowest levels of damage while carbon panels presented the highest damage levels. Hybrid laminates can be applied as a compromise solution.

“…FMLs have the advantages of both metals and polymers such as high wear strength, impact resistance, high corrosion resistance, etc. (Asundi and Choi, 1997;Bahari-Sambran et al, 2018a, 2018bZhang et al, 2020). In this regard, Evancho (2001) has declared that the puncture resistance of glass-reinforced aluminum laminate (GLARE) is 50% higher than the aluminum alloy layer with the same thickness.…”

In the present study, the effect of thermal cycling and stacking sequence on the tensile behavior of fiber metal laminate (FML) composites containing glass and basalt fibers was investigated. To fabricate the FML samples, fibers reinforced epoxy composite were sandwiched between two layers of 2024-T3 aluminum alloy sheet. 55 thermal cycles were implemented at a temperature range of 25–115°C for 6 min. The tensile tests were carried out after the thermal cycling procedure, and the results were compared with non-thermal cycling specimens. Scanning electron microscopy (SEM) was employed for the characterization of the damage mechanisms. The FMLs containing four basalt fibers’ layers showed higher values of tensile strength, modulus, and energy absorption. On the other hand, the lowest strength and fracture energy were found in the asymmetrically stacked sample containing basalt and glass fibers, due to weak adhesion between composite components (basalt and glass fibers). The lowest tensile modulus was found in the sample containing glass fibers that was due to the low modulus of the glass fibers compared to basalt fibers. In the case of the samples exposed to thermal cycling, the highest and the lowest thermal stabilities were observed in basalt fibers samples and asymmetrically stacked samples, respectively. In accordance with the experimental results, a non-linear damage model using the Weibull function and tensile modulus was employed to predict the stress-strain relationship. The simulated strain–strain curves presented an appropriate agreement with the experimental results.

“…The examination by Zhang et al [11] explored the ballistic execution of two diverse primary fibre metal laminates exposed to high-speed diagonal effect by impact by rigid hemispherical nose projectile with 0 ∘ , 30 ∘ , 45 ∘ and 60 ∘ angles. Their results showed that the projectile diverges during the oblique impact, and the deflection angle diminishes with rising impact velocity.…”

Polymeric materials have exceptional mechanical properties, making them attractive for automotive, aerospace, defence and buildings industries. The numerical analysis of translucent polymeric materials' ballistic performance is investigated to analyse the deflection and perforation performance at high impact velocities. Computational methods are exploited to predict the ballistic performance of thick targets and projectile damage, and the results are validated against published works. The 3D numerical analysis is conducted by simulating plates and projectiles' mechanical performance that controls the deflection and ricochet procedure. Impact damage analysis is undertaken on monolithic Polycarbonate (PC) and Polymethyl methacrylate (PMMA) targets under various impact velocities, projectile's core density with inclined and normal impact angle. The results are analysed in terms of failure performance, depth of penetration (DOP), penetration path (POP), and residual velocity. The numerical analysis is further developed to investigate the projectile's impact velocity effects on the DOP and its direction. The results showed that the DOP changes linearly with the impact velocity, where the POP is as yet nonlinear. Extended Drucker Prager Strength (EDP) material model with the failure criteria of principal stress and tensile pressure failure is used to simulate the brittle-ductile PMMA target's performance under dynamic impact. Shock Hugoniots equation of state with plastic strain failure is conducted to affect PC plates' tensile performance.
