“…One of the recommended reuse routes for waste tires is to convert them into rubber particles as a possible alternative to the fine aggregates in concrete (1,2). Related studies have indicated that concrete containing rubber particles exhibits a better impact resistance, toughness, thermal insulation, and sound absorption, which are specially required in the construction of airports, surge guards and military protection (3)(4)(5). This study provides reliable insights into the recycling of waste tires into useful new materials.…”

This paper investigates the influence of silica coated rubber on the performance of rubber mortars. A classical Stöber sol-gel method is applied to produce a layer of silica coating on rubber particles, which is used to partially replace the fine aggregates in concrete. The effects of the surface-modified rubber particles on the flowability, mechanical strength, capillary water absorption rate, and microstructure of mortars are examined. The results show that the silica coating on the rubber particles reduces the contact angle between the rubber particles from 120° to 103° (i.e., by 17°) and changes the hydrophobic properties from strong hydrophobicity to weak hydrophobicity. The mechanical strengths of mortars are significantly improved by the incorporation of surface-modified rubber particles, i.e., from 41.60% to 44.86% (compressive strength) and from 7.80% to 26.28% (flexural strength). In addition, the incorporation of surface modified rubber particles increases the density of the mortar’s microstructure and enhances the interfaces with its surrounding pastes.

“…For the marine industry, they are used to reduce the vibration caused by the engines in order to provide a smoother ride as well as reduce the amount of damage done to the body when the ship is docked or docking [2]. In structures, shock absorbers are used to minimize the damage to the building or bridge in order to keep the damages to a minimum during an earthquake [3]. In this paper the shock absorber application is applied in the aerospace industry; the automotive industry; the marine industry; and the structural industry.…”

Shock Absorbers are a part of everyday life and have many different applications and uses. They are used for bridges, highways, buildings and cars to absorb the impact from the bumps, earthquakes and high winds. Different applications require different types of shocks and different materials. A rubber shock absorber cannot be used on a vehicle while a cylindrical shock absorber cannot be used on a highway. All the situations require a specific shape and type of shocks to be used for the required tasks.

“…This capacity not only improves driving comfort by buffering against road irregularities but also rapidly diminishes dynamic stress on vehicle components, thereby extending the vehicle’s longevity. Rail transit, too, requires vibration isolation to adhere to seismic safety standards and to reduce train-induced disruptions to neighboring infrastructure. , Aviation underscores the need for effective damping. Key areas such as pilot seats and landing gears are equipped to minimize disturbances from the engines and takeoff/landings to guarantee both pilots and passengers well-being .…”

Shock-absorbing materials play a vital role in various industrial sectors, including construction and transportation. Among these materials, natural rubber (NR) stands out due to its exceptional elastic and mechanical properties, coupled with its robust crack resistance. Nevertheless, with the rising demand for enhanced damping capacities, there is a need to further optimize the damping performance of NR. One direct approach is to blend it with high-damping rubber. Butyl rubber (IIR) is a prominent member of the high-damping rubber category. Integrating IIR effectively with the NR, however, presents challenges. These challenges arise from IIR's inherent characteristics, such as its low unsaturation, slower vulcanization rate, and restricted compatibility with NR. Addressing these challenges, our study employed isoprene and isobutene to synthesize a variant of butyl rubber with a higher degree of unsaturation�achieving an unsaturation level between 4 and 6 mol %. Notably, this heightened unsaturation significantly expedited the curing time of IIR and facilitated the concurrent vulcanization of both IIR and NR. Utilizing atomic force microscopy, we observed that the introduction of unsaturated double bonds ameliorated the compatibility between NR and IIR, leading to an interfacial region extending up to 1000 nm. Our tests using a dynamic mechanical analyzer and rubber processing analyzer demonstrated the material's damping temperature range. Furthermore, there was a noticeable rise in the loss factor (tan δ) at ambient temperature, which remains over 0.1 across both a frequency window of 0.2 to 5 Hz and a strain spectrum of 10 to 200%. This tan δ enhancement ensured the potential of these rubber composites for shock-absorbing applications.
