“…It was revealed that reinforcing the composites with OMMT nanoclay improved their mechanical properties. Li et al 28 investigated the NBR matrix and discovered that OMMT was uniformly distributed. For various filler loadings, Suresha et al 29 investigated the three‐body abrasion wear behavior of epoxy composites filled with OMMT and discovered that an increase in load and abrading distance increases the wear volume.…”

The advent of additive manufacturing has brought a paradigm shift in many engineering applications involving polymer composites. The current study aims at integrating artificial neural network (ANN) with experimentation to assess the wear properties of glycol‐modified polyethylene terephthalate (PETG) composites reinforced with organically modified montmorillonite (OMMT) nanoclay (1%, 3%, and 5% weight percentages). The specimens are fabricated using fused deposition modeling technology. The proposed composites are compounded and developed using a single screw extruder with a diameter of 1.75 mm. As per ASTM G99 standard, the tribological characteristics were investigated using sliding wear with the dry pin on disc arrangement. The data points owing to the wear properties of PETG/OMMT nanocomposites are collected with the aid of the experimentation, which is then used to train the ANN model using Levenberg– Marquardt backward propagation algorithm. The experimental results show that adding OMMT nanoclay at a 3% weight percentage improves the wear properties of the composites compared to virgin PETG. A scanning electron microscope study of the wear mechanism reveals that adding OMMT nanoclay to the proposed composites results in mild wear as opposed to heavy wear in the case of virgin PETG. The ANN model developed to predict the tribological performance of PETG/OMMT facilitates better predictability with 99.6% accuracy, thereby reducing the requirement of expensive experimentation and analysis. The proposed composites may be applicable in the prosthetic, aerospace and automobile industries.

“…Since the introduction of carbon black as the first reinforcing agent for rubbers in 1904, there has always been interest in the incorporation of naturally occurring fillers into elastomers. Thereafter, different sorts of fillers, like graphite, silica, and calcium carbonate, have been examined to yield elastomeric composites with superior physical and mechanical properties compared with gum rubber .…”

This paper reports on the reinforcing effects of different types of fillers, namely, nanoclay (NC), micron size calcium carbonate (MCC), and micron size recycled powder coating waste (MPCW), on the ultimate properties of acrylonitrile butadiene rubber (NBR) compounds. The microcomposites and nanocomposites were characterized by X‐ray diffraction and scanning electron microscopy, implying enlargement of d‐spacing of NC or intercalation of NBR chains and formation of exfoliated structure, while some agglomerates of MCC were detected. Curing characteristics of the studied composites showed that incorporation of the fillers into the NBR, in particular the NC, causes an increase in the torque, indicating a higher degree of crosslinking. Furthermore, different from micron size MPCW and MCC, the NC accelerated the vulcanization reaction. It was also found that the use of NC and MPCW results in a remarkable increase in the mechanical and rheological properties compared with pure NBR. All in all, variations in the aforementioned criteria were attributable to the extent of matrix/filler interaction reflected by scanning electron micrographs. The correlation established between the microstructure and characteristics of the prepared NBR composites can shed some light on how to develop composites with enhanced properties by incorporating waste materials into the polymers.

“…As is known, the performance of NBR will be considerably influenced by the content of acrylonitrile (AN). With increasing AN content, improved oil resistance, heat resistance and mechanical properties can be achieved [1][2][3][4][5]. On the other hand, the relatively poor performance (such as, resistance to low temperature, ozone resistance, compression strength, etc.)…”

Maleic anhydride grafted POM (MAH-g-POM) was prepared and used as the compatibilizer for nitrile butadiene rubber (NBR) modified by acetal copolymer (POM) in different proportions. It was found that MAH-g-POM had good compatibilization effect for the blends. Both DSC and XRD results indicated that the process of blending POM with NBR considerably influenced the crystallization of POM. The scanning electron microscopy (SEM) study of tensile fracture surfaces of the blends clearly showed that the compatibility of NBR/POM blends was enhanced with increasing POM content. Mechanical properties indicated that NBR/MAH-g-POM had relatively higher elongation at break but lower tensile strength than NBR/POM blend. The present work will supply a good insight into the formula design and further optimization of polymer composites or blends.
