“…The observed results are in good agreement with published studies on the investigation of metal foams (steel and aluminium foams) impregnated with polymers, such as polyethylene, polyamide, epoxy, expandable polystyrene and polyurethane [11][12][13][14][15]. They report that all of these polymers have a positive effect on the thermal and mechanical parameters of the hybrid foams (e.g.…”

“…We believe that in this way it is possible to achieve desired functionality necessary to satisfy requirements of a specific application. Few works have been published in this field [11][12][13][14][15][16][17][18][19], developing and testing hybrid foams based on both metal open-cell structures [12][13][14][15] and closed-cell foams [16][17][18][19]. Herein, further research in this field is presented in which the hybrid foam specimens of different sizes, combining aluminium alloy open-cell foam and two different polymer types, were developed, fabricated, tested and mechanically characterized.…”

Crush performance of multifunctional hybrid foams based on an aluminium alloy open-cell foam skeleton

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

“…In this context, filling these metallic skeletons with lightweight porous materials can be an interesting alternative to bulk polymers. Reinfried M. et al [14] explored the concept of hybrid foams, which consist of two different interpenetrating embedded foam-material classes. The idea behind the hybrid foams is to overcome the individual shortcomings of single-material foams by combining foams of two different material classes and therefore achieving synergistic property combinations that are relevant and beneficial for future applications.…”

This paper focuses on the development of hybrid structures containing two different classes of porous materials, nanocomposite foams made of polyurethane combined with graphene-based materials, and aluminum open-cell foams (Al-OC). Prior to the hybrid structures preparation, the nanocomposite foam formulation was optimized. The optimization consisted of studying the effect of the addition of graphene oxide (GO) and graphene nanoplatelets (GNPs) at different loadings (1.0, 2.5 and 5.0 wt%) during the polyurethane foam (PUF) formation, and their effect on the final nanocomposite properties. Globally, the results showed enhanced mechanical, acoustic and fire-retardant properties of the PUF nanocomposites when compared with pristine PUF. In a later step, the hybrid structure was prepared by embedding the Al-OC foam with the optimized nanocomposite formulation (prepared with 2.5 wt% of GNPs (PUF/GNPs2.5)). The process of filling the pores of the Al-OC was successfully achieved, with the resulting hybrid structure retaining low thermal conductivity values, around 0.038 W∙m−1∙K−1, and presenting an improved sound absorption coefficient, especially for mid to high frequencies, with respect to the individual foams. Furthermore, the new hybrid structure also displayed better mechanical properties (the stress corresponding to 10% of deformation was improved in more than 10 and 1.3 times comparatively to PUF/GNPs2.5 and Al-OC, respectively).

“…Recently, based on the multi-material concept, hybrid structures have been developed by combining the periodic open-cell aluminium foams [20][21][22][23][24][25] or Advanced Pore Morphology (APM) foam elements [26][27][28][29][30] with polymers in which the voids of an open-cell aluminium foams are completely infiltrated with a polymer. Results have demonstrated that the polymer lead to an enhancement of the compressive strength and energy absorption of the resulting hybrid structures compared to the conventional opencell aluminium foams.…”
