“…The order of heat build‐up is ACM > RCM > CM, consistent with that of hysteresis as discussed above, which is in agreement with the results in the literature 16. It is found that the surface temperature of the sample rose rapidly during the cutting and chipping process 17. Higher heat bulit‐up indicates that more energy during cutting and chipping process is changed into heat, and correspondingly less energy is used to demage the rubber molecule chains.…”

A novel, effective approach to improve the cutting and chipping resistance (CCR) of carbon black (CB)filled styrene butadiene rubber (SBR) composite was reported in this study. CCR of SBR was dramatically improved more than 30% by addition of 4 phr nanodispersed clay (NC), while not decreasing the stress at 100% and the Shore A hardness of the composite. The curing characteristics, loss tangent (tan d), and the strength of filler network of the composites were further measured by a Disk Oscillating Rheometer and a rubber processing analyzer, respectively. It was found that the addition of NC led to a slightly lower crosslink density, higher tan d, and stronger filler network, which contributed to the higher CCR. Therefore, the novel layered NC is more efficient in improving CCR when compared with CB. The results are expected to promote the application of NC in rubber industry.

“…A similar situation may be noted for a standard application of the original BFGoodrich tester. It was reported [11], for example, that the lab compound rating obtained by means of BCCT showed a completely opposite trend to that from the real world field performance, and further study was recommended to explain the observed results.…”

“…The tester was proposed for analyzing the CCC resistance of different polymers and polymer-based composites. Application of this tester was reported in [8][9][10][11] for analysis of the effect of different parameters (the state of cure, factory processing variations, surface temperature of a sample, etc.) on CCC resistance.…”

A new experimental method and corresponding analytical model were proposed to characterize cut, chip and chunk wear for elastomeric materials. According to the model, the wear is considered as a time-dependent nonlinear process. Experimental verification of the proposed model was conducted for four typical elastomers. It was shown that the amount of wear loss may be accurately described by the model, based on two independent material parameters. The effect of each parameter on cut, chip and chunk wear resistance was analyzed in detail. High statistical reliability was shown for the proposed material parameters and corresponding analytical predictions. The proposed method may be recommended as a robust predictor of cut, chip and chunk wear processes for rubber and, potentially, other polymer materials.

“…The CC phenomenon is complex, yet traditional CC test methods for the rubber laboratory employ simple devices where loading conditions cannot be changed significantly, and sample weight loss is the only information collected [3][4][5][6]. This aim of this paper is to demonstrate a new instrumented approach for predicting CC resistance of rubber compounds used in tires and other applications such as rubberised tracks and conveyor belts.…”

Understanding the cut and chip (CC) effect in rubber is important for successful product development for tires used in off-road or poor road conditions and for other demanding applications of rubber. This research describes a laboratory testing method for characterising the CC fracture behaviour of rubber using a device that controls and records multiple applied loads and displacements during cyclic impact to the surface of a solid rubber specimen to mimic and quantify the CC damage experienced by tire tread compounds. To study the capabilities of the instrument, three model compounds were studied that are based on carbon black reinforced compounds of common elastomers used in tire treads: natural rubber (NR), styrene-butadiene rubber (SBR), and butadiene rubber (BR). These polymers have well-established CC tendencies in field performance of tire treads, with NR exhibiting the best CC resistance followed by SBR and finally BR. The same trend was found with the rubber impact testing approach that allowed the CC behaviour to be quantified using a new physical parameter which is the CC propensity (P). The relative ranking for CC resistance for the three compounds followed the fatigue crack growth resistances of the materials but was exactly opposite to the ranking of DIN abrasion resistance. This provides evidence that CC damage from impact by mm-scale asperities and abrasion of rubber against μm-scale asperities exhibit distinct characteristics in rubber.
