“…Synthetic elastomers like silicone rubber (SR) are commonly found in application in industries such as aerospace, medical, and electronics. Owing to their excellent environmental inertness, thermal stability, and insulating properties [1,2], most sectors prefer SR. Silicon rubber properties can be radically improved by adding nanofillers like carbon black (CB), carbon nanotube (CNT), graphite, nano C e O 2 [3,4]. Similar works can be found in literature that show the influence of graphene oxide addition on resistivity and dielectric constant [5], thermal stability with the function of iron oxide and CNT filling [6], and tribological study [7] of various nanocomposites performed on the SR composite.…”

Nanocomposite made by blending nano-montmorillonite (MMT) and Silicon Rubber (SR) for mechanical and tribological performance is explored in this work. Different configurations of MMT/SR nanocomposite, with 0, 0.5, 2 and 5 wt % of MMT are manufactured by two roll mixing methods. Noticeable improvement in the mechanical and tribological performance is observed, which is also justified by a morphological study of fractured and wear surfaces through SEM. Two percent of MMT loading is found to be the optimum content that shows excellent performance compared to other compositions. The performance improvement can be linked to the good interfacial interaction between the MMT and SR. Statistical modeling through ANOVA is carried out for tribological performance, which reveals the influence of load on the coefficient of friction (COF) and the influence of sliding distance on the wear rate.

“…The mechanical and wear characteristic of rubber components can be one essential factor when deciding its candidature for a particular application. Adding graphene and nano-C e O 2 as a filler in SR showed a decrease in the COF [4]. Reinforcement with CB enhanced the mechanical and tribological properties [8].…”

“…Zheng [ 17 ] explored the mechanical and frictional properties of graphene–silicone rubber composites by analyzing the microscopic fracture and friction mechanism of samples, which revealed that the lubrication and enhancement of graphene were important factors to improve the mechanical and frictional properties of silicone rubber composites. Han [ 18 ] prepared graphene/CeO 2 phenyl silicone rubber composites and studied its frictional properties before and after high temperature aging. The results indicated that the π–π conjugation of graphene with phenyl groups had significant effects on the wear resistance of rubber matrix.…”

The dry/wet environment's effects on the sliding friction properties of fabric–silicone rubber composites are studied, and the wear resistance of polyester fabric is evaluated. The yarn directions of the fabrics (inner and outer) have significant influence on the coefficient of friction (COF) of fabric–silicone rubber composites during sliding friction due to the difference in fabric texture and yarn modulus. The COF's variation laws of fabric–silicone rubber composites under different vertical loads and sliding rates are observed, respectively. Additionally, the outer fabric is more sensitive to the changes of vertical loads than those of the sliding rates under the wet environment, which can be attributed to the destruction of the fabric original structure by high load, resulting in the fabric fibers' pulling and breaking during the steel ball's sliding. This study provides new ideas for the design of fabric–silicone rubber composites applied in friction conditions and complex environments.

“…[7] However, due to poor wear resistance and tear resistance, the applications of silicone rubber under complex working conditions are greatly restricted. [8] The combination of fabric and rubber is an excellent structural form to improve the problem of poor wear resistance and tear resistance of the rubber matrix. [9] However, due to the low surface energy, the bonding quality between fabric and rubber has become a key indicator to evaluate the service safety and reliability of fabric-rubber composite components，which is also one of the most prominent problems that plagues many scholars.…”

The effects of titanate on the mechanical properties of silicone rubber and peel strength of polyester fabric with silicone rubber are studied. The tests show that the hardness and mechanical properties of silicone rubber containing 0.2 phr titanate are similar to those of pure silicone rubber, and the peel strength (1.11 N/mm) between fabric and rubber matrix without inner fabric is the highest in the test groups. Fourier transform infrared spectra (FT-IR) and contact angle test indicate that the surface wettability of silicone rubber is effectively enhanced with the addition of titanate, which is a key factor to improve the bonding properties between silicone rubber and polyester fabric because of the more adequate contact between the adhesive and silicone rubber surface.Due to the difference in the modulus of the fabric along different yarn directions, the peel direction has a significant effect on the peel force between the outer fabric and silicone rubber.
