This study presents experimental studies on thermal dissipation, thermal conductivity, and specific heat measurements of rubber mixtures reinforced with cord fabrics manufactured with three different PA 66 used in air suspension bellows. The studies were carried out between 20-160 °C. The cord fiber type and features used as reinforcement material within the rubber matrix significantly influence thermal properties. It has been observed that the amount of elastomer used in rubber composite mixtures also affects the thermal properties and approaches the properties of the matrix material. The thermal dissipation values of cord fabric reinforced rubber composites tend to decrease depending on the temperature. The heat flow perpendicular to the axis of the cord threads, the heat conduction rate is limited by the properties of the matrix, and the thermal properties of the composites approach the properties of this component. Because of the thermal properties of the progress perpendicular to the cord fiber of thermal resistance of cord fabrics, Increasing thermal conductivity and dissipation have been seen depending on the number of twists in a unit length for cord fiber. The thermal dissipation parallel to the fiber direction, the thermal dissipation perpendicular to the fiber direction and the thermal dissipation properties of the matrix were compared. As a result, it has been observed that the number of twists increases the thermal contact resistance by affecting the amount of compressed air in the composite samples and decreases the effective thermal conductivity perpendicular to the fiber array direction.

The objective of this study was to evaluate the effects of heat and moisture on the characteristics and tensile properties of resorcinol-formaldehyde-latex (RFL)-coated rayon cords and their adhesion to the natural rubber (NR)/styrene-butadiene rubber (SBR) matrix. The water absorption ratio, shrinking percentage, breaking force, and elongation at break of the cords, which were treated under various temperature-humidity conditions, were tested, and an attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy was used to investigate the chemical changes of the outer RFL layer. The static adhesion was investigated by an H pull-out test, and the evolution of the adhesive properties of the RFL-coated rayon cord/rubber matrix was tracked by an elastomer testing system. A scanning electron microscope (SEM) was employed to observe the interfacial fracture caused by both H pull out and fatigue. The results of this investigation show that the moisture absorption significantly affects the characteristics and the mechanical properties of rayon cords. The chemical state of the RFL layer and the static adhesion of the cord/rubber matrix were not obviously affected, but the interfacial fatigue life was extended due to the decrease of the load in the second of three fatigue stages, which was caused by a reduction in the modulus of the rayon cords.

The effects of various coupling agents on the characteristics and properties of a natural rubber (NR)/styrene–butadiene rubber (SBR) matrix and its adhesion to continuous basalt fiber (CBF) cords were studied. Four types of silane‐based and two types of titanate‐based coupling agents were added separately to the rubber matrix during the mixing process. The processability of the rubber compounds and the mechanical and tension fatigue properties of the vulcanizates were evaluated. The static and dynamic adhesion between the CBF cord/rubber matrices were investigated using the H pull‐out test and an elastomer testing system, respectively. The results showed that the effects of the coupling agent were controlled by its chemical structure, and it was found that the addition of (3‐aminopropyl)triethoxysilane was the most effective for enhancing the interfacial fatigue properties, due to the combined improvements of the initial adhesion, interfacial stress states, and the fatigue property of the rubber matrix. © 2018 Wiley Periodicals, Inc.
