“…Before the RFL dip is applied, the aramid cord is generally pre-activated with, e.g., an epoxy-based dipping system, to improve the chemical interaction between fiber and RFL [3][4][5][6]. As an alternative to this additional dipping step, adhesion activated aramid fibers have been developed and commercialized in the past [7,8].…”

The use of aramid fibers as a reinforcing material in both tires and mechanical rubber goods, such as hoses, belts, etc., is growing. In these dynamic applications, the adhesion between fiber and rubber is critical. This can be optimized by activating the aramid with an epoxy formulation, followed by RFL (Resorcinol Formaldehyde Latex) treatment.In the past, various combinations of analytical techniques have been used to study the relationship between the fiber surface treatment, the resulting microscopic interphase structure and the macroscopic rubber properties. The fundamental knowledge acquired from these past studies has been exploited here to investigate the effect of oily finish components on the aramid-rubber adhesion. For this purpose, aramid yarn has been treated with various combinations of an adhesion improving (epoxy-amine) component and a processability improving (oily) component.Contrary to general belief, the oily components do not directly reduce the SPAF (Strap Peel Adhesion Force) to rubber, rather show some positive effect. Furthermore, there is a relative broad 'safe' oil range, i.e., fluctuations in the amount of oil will not directly lead to adhesion problems. This is in line with earlier observations, but this study using appropriate analytical techniques provides quantitative confirmation and additional understanding of the fundamental principles behind these effects.

The interfacial adhesion between fibers as reinforcing fillers and thermoplastic matrices is a key requirement for obtaining effective reinforcement. Therefore, in situ polymerization of styrene onto polyethyleneterephthalate and in situ bulk polymerization of the same monomer on aromatic polyamide (Kevlar-aramid) fibers were carried out. In both cases, divinyl benzene was used as crosslinking agent in order to ensure the presence of reasonable amount of covalently bonded and nonextractable polystyrene on and/or onto the fibers. This treatment enhances the interfacial adhesion of investigated fibers to polystyrene matrix. The fibers were located in the matrix in continuous and uniaxially aligned form using a new injection moulding technique. A relation between the per cent change in weight of treated polyethyleneterephthalate and relative increase in the tensile strength of corresponding treated fiber-polystyrene composites was established. Some factors affecting the interfacial adhesion between investigated fibers and polystyrene matrix were discussed.

“…Therefore, high-performance organic fibers, for example, aramid fibers and ultrahigh molecular weight polyethylene (UHMWPE) fibers, have been recognized as good candidates for tire cords due to their high tensile and impact strength, low density along with excellent toughness. [11][12][13] Recently, high-strength-high-modulus polyimide (PI) fibers have drawn tremendous attention because of their superior comprehensive properties including outstanding mechanical properties, good dimensional stability, preeminent thermal, and aging resistance, which can be certainly used as the reinforcements for cords/rubber composites. 14 Nevertheless, on account of their commercially unavailable, the applications of high-strengthhigh-modulus PI fibers as skeleton materials in rubber composites have seldom been touched.…”

High-strength-high-modulus polyimide (PI) cords reinforced natural rubber (NR) composites are prepared, and the PI cords are treated with resorcinolformaldehyde-latex (RFL) adhesive to enhance the interfacial adhesion with NR matrix. The influence of RFL adhesive variables, such as the ratio of R/F and RF/L, on the adhesion between PI cords and NR is investigated. Furthermore, sorbitol glycidyl ether (SGE) and caprolactam blocked methylene diisocyanate (CBI) are adhered to the surface of the PI cords through a dipcoating procedure to introduce epoxy and NCO groups and graft with more RFL adhesive. The H pull-out force of SGE/CBI-RFL treated PI cords/NR composites reaches as high as 193.9 N, which is 580% higher than that of untreated PI ones. Additionally, the SGE/CBI-RFL treated PI cords/NR composites exhibit superior adhesion, aging, and fatigue resistance together with better mechanical properties as compared with SGE/CBI-RFL treated poly(paraphenylene terephtalamide) (PPTA) cords/NR composites.
