“…Only a few studies have explored fatigue life estimation methods for rubbers operating in a high-temperature environment. 2,9,10 Hussain et al 2 investigated and compared the mechanical properties and the fatigue lives of dumbbell rubber specimens subjected to uniaxial tension at 23°C (room temperature) and 40°C. The study concluded that exposure to a temperature of 40°C yields a lower tensile stress and a reduction in fatigue life compared with those at 20°C.…”

“…The crack nucleation mechanism of rubbers at high temperatures has been investigated by Weng and Huang. 10 The study employed filled natural rubbers to investigate thermal oxidation ageing, while scanning electron microscopy was used to monitor the crack growth during hightemperature fatigue. It was concluded that the crack is generated originally from a small hole and residual gas in some portions of the rubbers.…”

A fatigue experiment is carried out on filled natural rubber specimens with two different Shore hardnesses (45 and 50) and three different temperatures (23°C, 60°C and 90°C) under uniaxial tension loads. The measured fatigue life data obtained under different displacement loads are used to formulate fatigue life prediction models corresponding to different operating temperatures for the two hardnesses using the peak engineering strain as the damage parameter. The influences of the temperature, the stress softening at high temperatures and the hardness on the fatigue life of rubbers are measured and discussed. The proposed models are used to predict the fatigue life of a rubber mount for a powertrain mounting system. The validity of the prediction model is demonstrated by comparisons with the measured fatigue life data of the rubber mount at 90°C. A method for determining the damage parameters required for predicting the fatigue life is presented on the basis of the finite element model of the rubber mount. The Mooney-Rivlin constitutive constants of the hyperelastic rubber material are identified on the basis of the measured data on the specimens. Comparisons of the measured and the estimated fatigue lives of the rubber mount at 90°C revealed reasonably good agreement. The ratio of the predicted fatigue life to the measured fatigue life was within a factor of 2 under the range of loading conditions considered.

In the present work, functionalized liquid isoprene rubber (FLIR) was used to improve the filler dispersion and filler-rubber interaction in the silica filled natural rubber system. By the infrared spectra and scanning electron microscopy, it was proved that the FLIR was successfully grafted on the silica and the functionalized silica was dispersed in the NR matrix homogeneously. Based on the real-time crack tip morphology monitoring method, the influence of FLIR on the crack growth behavior of NR filled with silica was analyzed. By the adding of FLIR, the crack resistance of the natural rubber embedded with functionalized silica is remarkably increased. When the weight ratio of FLIR to silica is 3:10, the NR composite has the best crack resistance. V C 2015 Wiley Periodicals, Inc.J. Appl. Polym. Sci. 2016, 133, 42972.

Pyrolysis technology has appeared a long time ago, but it has not been widely recognized and used in the area of waste plastic/rubber management. The key reason is that the high energy consumption of pyrolysis is the most important problem that plagues the further development of pyrolysis. Prior to the pyrolysis of waste plastics/rubbers, in addition to dehydration and drying can save part of the energy consumption of pyrolysis, in this study, we have first reviewed and discussed high irradiance exposure to artificially accelerate the aging process of waste plastics/rubbers as pretreatment. The results from our preliminary experiments show that the pyrolysis process of the plastic that has undergone UV accelerated aging was speed up, accordingly to achieve saving energy in thermal cracking.
