“…One of the reasons is that the elastic modulus was calculated with strain up to 3% whereas the DMA only presented the dynamic strain up to 2%. Together with the differences in testing frequency and the input signal (sinusoidal for DMA, triangular for quasi-static test) which led to different level of energy input per cycle, it is difficult to find a corresponding relationship between the results obtained from these two tests [12,23].…”

“…In a similar way to any conventional CNTs embedded in polymer matrix nanocomposites two main damping mechanisms exist in the MWNT core: the energy dissipation caused by (a) CNT-polymer interfacial sliding and (b) the energy dissipation caused by the CNT-CNT sliding [12]. Unlike conventional polymer based nanocomposites that are mainly characterised by the stick-slip mechanism at the CNT-polymer interface, the MWNT core contains more entangled CNTs that provide a larger CNT-CNT interface, and therefore would dissipate energy mainly through the CNT-CNT interfacial sliding.…”

“…In the classical polymer/carbon nanotube (CNT) composite with nanoparticles embedded in the polymer matrix, the three interface couplings that induce energy dissipation are the polymer-nanotube, the nanotube-nanotube interfacial sliding, and the coaxial sliding of the tube walls within the multiwall carbon nanotube (MWNT) [12]. Polymer-nanotube sliding is determined by the CNT/polymer interfacial bonding and dispersion quality [13,14], whereas nanotube-nanotube sliding within entangled CNTs is closely related to the filler content.…”

“…Presently, the research on SiCCMC focuses mainly on conventional properties and manufacturing processes, and research on its damping properties is lacking. Aluminum (Al) and its alloys are widely used, due to their low density and high strength [12][13][14][15]. It has been reported that adding SiC particles to the Al matrix improves the damping capacity of composites [7,16,17].…”

In this paper, we describe how an aluminum alloy-reinforced silicon carbide ceramic matrix composite (SiCCMC) with excellent damping capacity and storage modulus was fabricated by infiltration. The effects of silicon (Si) on the microstructure and damping capacity of the composite were studied. The interface bonding and damping mechanism involved were also discussed. The results show that composites with high damping capacity can be obtained by infiltrating SiC ceramics with aluminum alloy. The residual Si in the SiC ceramic had little effect on the damping capacity, and it provided the passage of aluminum alloy into the interior of the SiC ceramic. The aluminum atoms penetrate the SiC particles by diffusion. Optimal composite damping capacity was obtained when the Si content in the aluminum alloy was 15 wt. %, because the AlSi/SiC interface friction dissipated most of thermal energy. Ti3SiC2 formed on the surface had little effect on the damping capacity. Additionally, by changing the Si content in the aluminum alloy, the strength and damping capacity of the composites can be controlled.

Stiffness, Energy Dissipation, and Hyperelasticity in Hierarchical Multilayer Composite Nanocoated Open‐Cell Polyurethane Foams

The manufacturing, testing, and modeling of a class of open‐cell polyurethane (PU) foams doped with multiwalled carbon nanotubes (MWCNTs) and nano‐PU dispersions (PUDs) and subjected to quasistatic cycling compressive loading at large deformations are described. The doped nanoink foams are produced using a multiple‐step dip coating technique that makes the development of nano‐based porous materials by postprocessing existing off‐the‐shelf open‐cell foams possible. Tests are conducted up to 18.5% of compressive strain to identify loading/unloading moduli and energy absorbed after five cycles of stabilization. Hyperelastic Ogden models also considering the Mullins effect for cyclic loading are used to identify the constitutive parameters for these foams. The results show that the use of MWCNT layers provides an effective increase in the stiffness and energy absorbed compared with pristine and nano‐PUDs‐treated foams. The volume average energy absorbed after the stabilization cycles is increased by 200% compared with the pristine foam when the MWCNT layers are used. The parameters of the constitutive models extracted from the tests show that these nanoink foams are modeled following state‐of‐the‐art hyperelastic representations.
