Composite materials gain huge interest from researchers due to its advantages and flexibility. Strength and properties that can be adjusted based on the needs and applications is a specific advantage of composite materials. Since these advantages can be applied in many fields, composite materials often clustered in multifunctional materials. This study aims to lists and classified the progressive development of multifunctional composite materials that found and already proven can be applied in many applications. This study also gives data that can be driven to readers from different backgrounds and used it for further purposes. The results are shown that the progressive development of multifunctional composite materials not only one step forward in the technical achievements but also the energy and environment-related to human ecosystems.

“…The results of the interlaminar shear tests are displayed in Figure 6 in comparison to the measured arithmetic mean surface roughness. With a maximum value of 28 MPa for mechanical blasting, a significantly higher value can be determined than those measured on overlap joints of the same material combinations in [22]. On blasted specimens, residues of the FRP can be seen on the surface, which is due to the cohesive failure of the composite material.…”

“…The investigation of different surface treatment processes for aluminum AA6082 components in thermoplastic-based hybrid laminates CAPAAL showed that plasma electrolytic anodic oxidation and mechanical blasting lead to less than 20 MPa in a simple lap shear test [22]. One possibility to determine the shear strength is the examination of thermally joined single lap samples, which are easy to produce but do not reflect the real manufacturing process of hybrid laminates.…”

Hybrid laminates consist of layers of different materials, which determine the mechanical properties of the laminate itself. Furthermore, the structure and interfacial properties between the layers play a key role regarding the performance under load and therefore need to be investigated in respect to industrial applicability. In this regard, a hybrid laminate comprised of AA6082 aluminum alloy sheets and glass and carbon fiber-reinforced thermoplastic (polyamide 6) is investigated in this study with a focus on the influence of aluminum surface treatment application on tensile and fatigue behavior. Four different aluminum surface treatments are discussed (adhesion promoter, mechanical blasting, phosphating, and anodizing), which were characterized by Laser Scanning Microscopy. After the thermal consolidation of the hybrid laminate under defined pressure, double notch shear tests and tensile tests were performed and correlated to determine the resulting interfacial strength between the aluminum sheet surface and the fiber-reinforced plastic, and its impact on tensile performance. To investigate the performance of the laminate under fatigue load in LCF and HCF regimes, a short-time procedure was applied consisting of resource-efficient instrumented multiple and constant amplitude tests. Digital image correlation, thermography, and hysteresis measurement methods were utilized to gain information about the aluminum surface treatment influence on fatigue damage initiation and development. The results show that fatigue-induced damage initiation, development, and mechanisms differ significantly depending on the applied aluminum surface treatment. The used measurement technologies proved to be suitable for this application and enabled correlations in between, showing that the hybrid laminates damage state, in particular regarding the interfacial bonding of the layers, can be monitored not just through visual recordings of local strain and temperature development, but also through stress-displacement hysteresis analysis.

“…[7][8][9] Multi-layered fibre-metal-laminates (FML) as a combination of light metal semi-finished products with fibre-reinforced plastics in multi-layer design links the advantageous properties of both material classes and can be used to design an improved material behaviour. [10][11][12][13][14][15] A well-known example of a fibre-metal-laminate is GLARE, where glass fibre-reinforced epoxy layers and aluminium sheets are used. [16][17][18][19][20] In contrast, the present study is focussed on the usage of thermoplastic matrix materials, which offer significantly more energy absorption than thermosets, and thus are preferably used for impact-specific laminates.…”

The combination of thin light metal sheets with fibre-reinforced thermoplastic layers in multi-layered fibre-metal-laminates advantageously combines the properties of both material classes. In this way, components can be developed which have both significantly increased specific properties (strength and stiffness with respect to density) and high energy absorption capacity compared with conventional design with mono materials. However, the structural behaviour of crash structures is decisively determined by material behaviour of the thermoplastic and metal constituents as well as the interface properties between both constituents and the corresponding delamination behaviour. To evaluate the structural response of multi-layered fibre-metal-laminates under highly dynamic loading conditions, Charpy tests were performed, where the test parameters, light metal material configuration, support length and laminate thickness, were varied. Moreover, the metal sheet surfaces were pre-treated by embossing to achieve different surface topologies. The influence of the different test parameters on the specific energy absorption capacity was characterised by the analysis of force–displacement curves.
