“…This means that there is a strong interaction between the surface of the substrate and the liquid drop (γ SV > γ SL ). It should be noted that the surface free energy values generated by abrasive water jet texturing are higher than those obtained in blasting tests in other studies with values close to 30 mJ/m 2 [32].…”

“…While glass particles are spherical, corundum particles have cutting edges, which are close to the geometry of the abrasive particles in the water jet. This allows the particles to remove a greater amount of material on impact with the surface, generating a rougher surface as indicated in the results of Santhanakrishnan et al [32].…”

“…Finally, an impact angle of 90 • and an impact distance of 100 mm were set. These parameters were based on literature on texturing of steel by shot blasting prior to bonding operations with thermoplastic matrix composites (CFRTP) [32]. The particle sizes were 630 µm for corundum and 425 µm for glass spheres and were based on previous studies using these types of abrasive particles [21,32].…”

“…Surface quality was evaluated in terms of Rt in order to obtain a better understanding of the maximum distance between peaks and valleys generated by each texture. Three measurements were made in order to obtain a mean value using a roughness-meter (Mahr Perthometer PGK 120, Göttingen, Germany) following ISO 4287 standard [21,32]. In this way, in order to obtain a surface with a high surface activation for subsequent bonding operations, high Rt values are considered as good surface quality.…”

“…A relationship between the free surface energy generated by different blasting conditions and the surface quality obtained has been carried out by Santhanakrishnan et al [32].

Surface modification by different technologies prior to joining operations or improving tribological properties is a point of great interest. Improving surface activation by increasing the roughness of the metal is a relationship that is becoming more defined. In turn, an increase in surface wettability by evaluating contact angles indicates surface activation by obtaining a high surface free energy. Technologies such as shot blasting and laser surface texturing (LST) have generated several scientific studies where they have identified the influence of parameters on the formation of rough surfaces with defined patterns. However, the application of abrasive water jet texturing (AWJT) has been little studied as an alternative. This article compares these technologies in the texturing of a carbon steel s275 in order to identify the relationship between surface quality and surface activation. It has been determined that AWJT produces the highest Rt values close to 64 µm with a cross feed of 0.45 mm and a traverse speed of 5000 mm/min. Furthermore, LST obtains the best values of free surface energy by combining a power of 20 W with a frequency of 20 kHz and a sweeping speed of 10 mm/s. Finally, contour diagrams have been obtained which relate these variables to the texturing parameters.

The aim of this study is to investigate the effects of metal-composite interface (MCI) adhesive quantity on the energy absorption and failure behavior of fiber metal laminates (FMLs) under ballistic impact. The dynamic shear and ballistic impact tests were systematically conducted, and CT scan was employed to quantitatively investigate the damage and failure mechanisms of the FMLs.The results reveal that the dynamic shear strength of MCI initially increases and then remains constant with the increase in the adhesive quantity at a constant strain rate. Moreover, the MCI adhesive quantity has a certain influence on the impact energy absorption of FMLs, and the degree of influence is related to the impact velocity. At an impact velocity of 360 m/s, the difference of energy absorption is maximal, approximately 14.7%. The distribution of total debonding area changes with increase in the adhesive quantity. When the impact velocity is 212 m/s, compared to FMLs with the lowest adhesive quantity, the total debonding area of FMLs with the highest adhesive quantity decreases by 774.57 mm 2 (9.20%), otherwise the debonding area near the rear aluminum alloy sheet increases by 595.94 mm 2 (58.99%).

[1,2] Combining the merits of both FRCs and metal alloys, FMLs not only exhibit high specific strength, specific stiffness, and excellent fatigue characteristics but also show outstanding load bearing capacity, impact resistance, and residual strength. [3][4][5] Therefore, FMLs are widely used in the aviation industry, such as wings, fuselage, and empennage of aircrafts, [6][7][8] and they also exhibit immense application potential in transportation, [9] armor protection, [10] and other fields.The mechanical properties of FMLs are primarily governed by the type of reinforcement fiber. [7] Currently, carbon fiber, glass fiber, and aramid fiber are mainly used as the reinforcement fibers in FMLs. [11] Ultrahigh molecular weight polyethylene (UHMWPE) fiber is a highperformance fiber with high modulus, low density, and outstanding energy absorption capacity. Therefore, it is extensively applied in the development of protective armors for soldiers and other military fields. [12][13][14] Over
