“…Moreover, the development of cracks or debonding in the composite materials as an adherend also has an effect on stress distribution in the adhesive layer. Botelho et al [19] and Park et al [20] concluded that in Glare ® laminates, the critical challenge is to find practical methods of surface treatment in order to obtain a durable structure because the interface bonding the aluminum and epoxy-glass layers plays an important role in load transfers through the structures. Botelho [21] mentioned that it was possible to manufacture hybrid laminates with proper consolidation between the polymer composite and metal layers thanks to good wettability, because there is no visible presence of voids (porosity) in the metal layer at the interface with the composite [21].…”

Fiber metal laminates (FMLs) were initially developed under the motivation of the aerospace industry. Generally, they consist of aluminum and high strength glass fiber in polymeric layers, but the new challenge is to apply them with a carbon fiber. Pretreatment of aluminum is the main factor responsible for the adhesion between metallic and polymeric layers. The shear strength test a very popular method in the experimental joint of two components. In this article, the main aim was to compare the surface pretreatment and configuration of fibers in FMLs based on aluminum with glass and carbon fibers. The decisive factor of strength in adhesive or cohesive failure is first the type of fibers, and second, the surface preparation.

“…Three different solutions for CARALL were compared by Ning et al: the enhancement of the composite-metal interface due to the addition of nanoparticles and the chemical etching or mechanical patterning on the surface of the metal sheet. The influence of the surface treatment of the sheet for the production of GLARE was investigated by Mamalis et al [7] and Park et al [8]. The advisability of a glass layer at the metal/composite interface of a CARALL was evaluated by Jakubczak et al [9].…”

FML (Fibre Metal Laminate) is a hybrid material that presents outstanding structural properties, such as resistance to cyclic and dynamic loads, together with low specific weight. This material consists of metal sheets alternating to composite material layers. In the present work, the ILSS (Interlaminar Shear Strength) was evaluated for different types of carbon fibre/aluminium FML, produced varying the layer thickness and the bonding solution of layers. In fact, FMLs consisting of one or two metal sheets (a parameter strictly connected to the layer thickness, as the metal/composite volume fraction was kept at constant value) and bonded with structural adhesive or prepreg resin were considered for this study. The ILSS was determined according to the three-point bending method with short beam specimens. The experimental tests evidenced an effect of the adhesion methodology on the ILSS value, while the layer thickness did not influence the interlaminar strength. The mechanical behaviour after the maximum load point was investigated too, evaluating the trend of the shear stress as a function of the loading nose displacement.

“…The resin system is injected into the mold and acts as the matrix for the FRP as well as an adhesive towards the metal component. It is important to minimize the formation of voids during this step as they directly influence the quality of the final part as well as the interface strength of the hybrid part [7][8][9]. In addition, the surface of the metal structure has a big impact on the interface strength [8,10].…”

This work shows a new way of single lap shear specimen production for hybrid metal-composite materials, which can be used to characterize process-induced interface property variations. Due to this special procedure, the specimen manufacturing can be done production-related and with a homogenization of the thermal stresses occurring in the joint area of the hybrid at each specimen. The exemption process of the specimen is kept in a minimum invasive way, not affecting the interface in the tested zone. The influence of the metal surface structure specifically created by micro form milling as well as the influence of the curing temperature on the maximum shear strength of the interface, were investigated. Finally, the driving failure mechanisms were identified and described.
