The incorporation of viscoelastic materials represents an effective strategy to reduce the vibratory level of structural components. Thermoplastic vulcanizates (TPVs) are a special type of viscoelastic material that combines the elastomeric properties of rubbers with the easy processing of thermoplastics. In the present work, we propose innovative ways to improve the damping properties of high-performance TPVs by using rubbers with carboxylic functionalities. For that, TPVs from physical blends of carboxylated hydrogenated acrylonitrile butadiene rubber (XHNBR) and polyamide 6 (PA6) were prepared. The chain dynamics of different mixed crosslink systems containing peroxide, metal oxides and hindered phenolic antioxidants were investigated in order to find the most suitable strategy to design a high-performance TPV system with upgraded damping properties. The results indicate that the damping performance of the TPV system can be tailored by controlling the type and magnitude of the bonding interactions between the mixed crosslink system and the XHNBR rubber phase. Therefore, this study demonstrates the potential of TPV systems containing carboxylic rubbers as high-performance damping materials.

“…Conventionally, elastomers filled with a variety of special fillers like lead chippings, hollow tubes, ferrous‐ferric oxide particles, titanium dioxide, cork, chopped carbon fibers are used as vibration damping composites . The hysteretic damping of the elastomer combined with the intrinsic damping nature of the fillers and interfacial sliding between fillers and matrix forms the basis for the vibration damping capability of these composites . However, the requirement of high level of filler loading imposes a significant weight penalty as well as the reduction in ultimate properties.…”

This work deals with the study of effect of multiwalled carbon nanotubes (MWNT) on the tensile hysteresis behavior of carboxylated nitrile rubber composites under various cyclic strain levels (5, 25, and 300%). The presence of thermo‐labile ionic crosslinks as well as interfacial stick‐slip motion of filler in the matrix was found to enhance both Mullins effect and hysteretic damping. Hysteretic damping reached a maximum of 37% for 0.050 volume fraction of MWNT at medium strain (25%). The crosslink density measured through equilibrium swelling method revealed that the degree of ionic crosslinking decreased with increase in MWNT content, which was confirmed by infrared spectroscopy. Transmission electron microscopic images showed that agglomeration of nanotubes was prominent at higher volume fractions of MWNT. Acoustic absorption capability, as measured by the impulse method, decreased with increase in MWNT concentration. The high hysteretic damping and low acoustic absorption make the nanocomposites a superior choice for structural vibration damping in underwater acoustic sensor systems. POLYM.

“…Especially bending vibrations are effectively damped by the elastomer layers on the principle of so called constrained layer damping (CLD) [2]. However, CLD is usually used by subsequently applying damping foil to existing structures, mostly to increase the comfort for the user [3]. HyCEML, on the other hand, offer an integrated CLD mechanism which, if properly designed, can make additional damping foils obsolete.…”

Hybrid carbon fibre-elastomer-metal laminates consist of alternating layers of carbon fibre reinforced plastics, elastomer layers and aluminium sheets. These laminates offer great potential for a lightweight structural material with adjustable damping properties. The material damping is strongly influenced by the viscoelastic properties of the elastomer layers which damp by the principle of constrained layer damping when the laminate is vibrated. In this study the material damping was experimentally characterised by three point bending dynamic mechanical analysis (DMA). In this regard, HyCEML specimens were tested on different frequencies and temperatures. The loss factor, storage-and loss modulus were measured to characterise the damping over the temperature and the frequency range. Time-temperature superposition was applied to determine the damping characteristics at higher and lower frequencies. The experimental results were compared to numerical studies on the basis of a characterisation of the single constituents. A test setup with a cantilever beam under free vibration was chosen for the comparison of experimental and numerical results. Detailed multi-layer finite element models were generated offering high flexibility in terms of type and number of finite elements especially in the direction of laminate thickness. For this purpose, existing material models were used to investigate the influence of each component on the system's damping behaviour. The damping in the free vibration experiments was determined with the logarithmic decrement at the free end. Also the numerically and experimentally determined first eigenfrequencies were compared. It could be shown that the laminate damping is strongly dependent on the glass transitions of both the carbon-fibre reinforced plastics and the elastomers. The numerically determined first eigenfrequency matched the experimental with a deviation of 10 %, the logarithmic decrement of the experimental results was more than 50 % higher. The damping behaviour of the HyCEM laminate, however, is underestimated by the numerical investigation, since nonlinear viscoelastic effects are not yet considered.
