“…The quasi-static tests were recorded by using a high-resolution video camera. A high cooled middle-wave infrared (IR) thermal camera FLIR SC 5000 [22] was also used to study the deformation and failure modes of the specimens subjected to the loading rate of 1 mm/s. The IR camera detected IR energy emitted from objects, converted it to temperature, and displayed an image of temperature distribution from the specimen surface.…”

Hybrid structures with epoxy embedded in open-cell aluminum foam were developed by combining open-cell aluminum foam specimens with unreinforced and reinforced epoxy resin using graphene oxide. These new hybrid structures were fabricated by infiltrating an open-cell aluminum foam specimen with pure epoxy or mixtures of epoxy and graphene oxide, completely filling the pores. The effects of graphene oxide on the mechanical, thermal, and acoustic performance of epoxy/graphene oxide-based nanocomposites are reported. Mechanical compression analysis was conducted through quasi-static uniaxial compression tests at two loading rates (0.1 mm/s and 1 mm/s). Results show that the thermal stability and the sound absorption coefficient of the hybrid structures were improved by the incorporation of the graphene oxide within the epoxy matrix. However, the incorporation of the graphene oxide into the epoxy matrix can create voids inside the epoxy resin, leading to a decrease of the compressive strength of the hybrid structures, thus no significant increase in the energy absorption capability was observed.

“…The compressive behaviour of the HS and nHS specimens and their individual components (PDMS, nPDMS and OCF) were studied using a servo-hydraulic dynamic INSTRON 8801 testing machine (maximum load 50 kN) at crosshead rates of 0.1 mm/s (quasi-static) and 284 mm/s (dynamic). The high-resolution video camera Sony HDR-SR8 and the mid-wave infrared (IR) cooled thermal camera Flir SC 5000 [33] were used in the quasi-static and dynamic tests in order to record the deformation and failure modes of the specimens. The temperature (heat) distribution on the specimen surface and the plastification front propagation can be efficiently observed by IR thermography to detect plastification zones in structures based on cellular metals [33].…”

“…In both cases, the upper compression plate was fixed while the lower plate compressed the specimens at prescribed rate. The specimens were monitored during testing by a high definition video camera and by a cooled middle-wave infrared (IR) thermal camera Flir SC 5000 (with frame rates up to 700 Hz) [22]. All foam specimens tested under dynamic condition were sprayed with black paint for easier monitoring of thermal emission.…”

“…The temperature (heat) distribution on the cellular structure surface and the plastification front propagation was observed by IR thermography [29]. IR thermography has proven to be an efficient technique to detect plastification zones in structures based on cellular metals, such as open-cell foam [30], closed-cell foam [31], syntactic foam [32], advanced pore morphology spherical foam [33] or even hollow structures filled by cellular metals (e.g. foam filled tubes) [34].…”

Multifunctional hybrid foams were developed and tested by combining aluminium alloy open-cell (OC) foam specimens with polymers, epoxy resin and silicone rubber. The rectangular OC foam specimens were impregnated with polymer, completely filling the voids. The aim of this work was to evaluate the effect of the polymer presence in the voids of aluminium alloy OC foam specimens (varying their size, e.g. height to width ratio) on the crush performance of the resulting hybrid foams. Quasi-static and dynamic uniaxial compressive tests and infrared thermography were used to compare the behaviour of hybrid foams with conventional (unfilled) OC foam specimens. Results show an improvement of the compressive strength and energy absorption capacity of hybrid foams, especially when infiltrated with epoxy resin. The results show that the epoxy leads to higher capacity of specific energy absorption of the hybrid foams, while silicone leads to lower capacity of specific energy absorption in comparison to the OC foam specimens. The high energy absorption values of
