“…An increase in modulus was observed with increasing fiber content. Similar studies 9,35,36 have reported that an increase in fiber content increases the storage modulus of the polymer matrix. This effect was more pronounced for the addition of 5 phr jute fibers, and the addition of 2.5 phr practically did not increase the storage modulus.…”

There is growing interest in replacing the synthetic reinforcements used for natural rubber (NR) composites with natural fibers from renewable, environmentally sustainable sources. Jute fibers may be suitable reinforcements for NR because they have a high tensile strength, which is comparable to other fillers such as glass fibers. Thus, we studied the incorporation of bleached jute fibers into NR, characterizing the mechanical, dynamic mechanical, and morphological properties of the composites. The addition of fibers to the NR latex was achieved by chemical coagulation, followed by vulcanization in a laboratory two-roll mixing mill. The elastic modulus at 100 and 300% elongation of the NR doubled after the addition of 10 phr of fibers without significant loss in the tensile strength or the elongation at break. The hardness was increased by 47%, and the storage modulus also increased, indicating the excellent interactions between the surfaces of the fibers and the NR matrix.

“…19 However, the degree of reinforcement generated by that solid particle is dependent on some important parameters, such as: aspect ratio, volume fraction, distribution, orientation, and interfacial interaction with rubber matrix. 20 Thus, data of morphometric parameters quantified from micro-CT (Table 3) are useful to support the rheological investigation described in the next section.…”

This study reports the reinforcement degree investigation of two types of rockwool fibers (F1 and F2), in nitrile rubber composites. The micro-computed tomography (micro-CT) 3D images showed that both fibers were well-dispersed in the NBR matrix, without a preferential orientation. The micro-CT analysis also allowed quantifying volume fraction, inter-fiber distance, and aspect ratio. Those morphometric parameters were used for supporting the composites rheological behavior assessment. Changes in the elastic modulus and phase angle followed the same trend of the inter-fiber distance values, regardless the type of fiber. Both volume fraction and aspect ratio data from the micro-CT analysis were used to predict theoretical values of elastic modulus using the Guth-Gold and modified Guth-Gold equations, and the results obtained were compared to the rheological experimental data. This analysis was helpful to better understand the rockwool fibers reinforcement degree differences in the production of the nitrile rubber composites.

This article presents an experimental and numerical study of short-fiber-reinforced rubber sealing composites (SFRC) at different stress amplitudes (1 MPa, 2 MPa, and 3 MPa). The curves of the maximum strain varying with the number of cycles were obtained by the fatigue test, and the damage modes of SFRC at different stress amplitudes were determined by scanning electron microscope. A finite element model (FEM) was established, where fibers distributed randomly and the stress-based fatigue damage model integrating with a bilinear tractionseparation law of the cohesive zone model was embedded in the fiber/matrix interface. The effect of different stress amplitudes on the fatigue damage of SFRC was investigated by FEM where the interfacial debonding behavior was considered. The predictions at stress amplitudes of 1 MPa are generally consistent with experimental data. The predictions at high stress amplitudes (2 MPa and 3 MPa) are agreeable with experimental data at low number of cycles.
