“…The addition of clay improves the mechanical strength of the CF/POM composite. The fillers' synergistic effect on improving Friction, wear behavior, and morphology was reported [5][6] [8,11] ( Mittal et al 2015) have systematically investigated the importance of surface treatment of MMT clay and its influence on the interaction with reinforced materials, resulting in better adhesion, which consequently influences friction and wear behavior of polymer composite. They found a decrease in the value of the frictional coefficient concerning the sliding time with the decrease in frequency level, keeping the normal load constant within the observed range.…”

The goal of the current study was to determine how different operating parameters, such as load, sliding speed, and sliding distance, affected the tribological behavior of composites consisting of 40% by weight of glass fiber and Polyphenylene Sulphide (PPS) with the varying percentage by weight of Bentonite clay. The study aimed to investigate the effects of different experimental settings on two distinct results: wear and coefficient of friction. This was made possible by utilizing a Taguchi L9 orthogonal array, allowing experiments to be performed at three distinct degrees of complexity. Six material samples totaling different weight percentages of bentonite clay were the subject of this investigation, which was carried out using a pin-on-disc setup as per ASTM G99. The outcome of this investigation revealed that for the virgin sample, the coefficient of friction increases with the increase in the applied average load. Also, it was observed that the rise in the average load reduced the coefficient of friction of the samples containing the Bentonite clay. Whereas an increased proportion of clay in the composite has shown a remarkable increase in the coefficient of friction value from 1% to 5%, a further rise in the clay proportion up to 7% shows a noteworthy reduction in the coefficient of friction value.

“…Among advanced fibers, CF is generally used as a reinforcing material for the thermoplastic matrix in automotive, electronics, and aerospace industries. 1,3,4 CF-reinforced polymer composites are attractive materials especially in aerospace applications due to their good mechanical and thermal properties, high corrosion resistance, and lightness, [5][6][7] especially weight being the critical factor. In addition, high-performance engineering thermoplastic poly(phenylene sulfide) (PPS) is the preferred matrix material for aerospace and automotive industries.…”

“…When literature was examined, it was seen that there were not much studies about the interface interaction of CF-reinforced PPS composites and CF surface treatment. Carnevela et al 6 examined the effect of CF-PPS interfacial adhesion on the local strain by using the digital image correlation technique. EP and industrial surface-treated CFs were used as reinforcing materials.…”

This paper aims to study the effect of different surface coatings of carbon fiber on the thermal, mechanical, and morphological properties of carbon fiber reinforced poly(phenylene sulfide) composites. To this end, unsized and different surface-coated carbon fibers were used. Prepared poly(phenylene sulfide)/carbon fiber composites were characterized by using Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, tensile test, dynamic mechanical analysis, and scanning electron microscopy. Tensile strength values of the surfaced-coated carbon fibers reinforced poly(phenylene sulfide) composites are higher than the unsized carbon fiber reinforced poly(phenylene sulfide) composite. The highest tensile strength and modulus values were observed for the polyurethane-coated carbon fiber reinforcement. Dynamic mechanical analysis studies indicated that polyurethane-coated carbon fiber reinforced composite exhibited higher storage modulus and better adhesion than the others. Differential scanning calorimetry results show that melting and glass transition temperature of the composites did not change significantly. Scanning electron microscopic studies showed that polyurethane and epoxy-coated carbon fibers exhibited better adhesion with poly(phenylene sulfide).

“…In such cases (such as composites or highly heterogeneous material), understanding the macroscopic behavior requires the description of the mechanical behavior in each phase. Then, there is a growing interest in trying to identify the spatially varying mechanical properties directly from full‐field measurement observations , which provide a versatile means for studying a material at several scales , in situ, in a non‐contact manner, and are ideal for capturing non‐homogeneous displacement fields that are usually present in composites. Furthermore, such an inverse problem (we generally denote in this paper as the ‘inverse problem’ the process of recovering the field of material parameters from the measured displacement field) should now be solved for three‐dimensional cases as literature has seen a growing focus on digital volume correlation (the 3D counterpart to DIC), through which the displacement fields within a heterogeneous body such as a composite ply can be recorded during mechanical loading .…”

SUMMARYThe post-treatment of (3D) displacement fields for the identification of spatially varying elastic material parameters is a large inverse problem that remains out of reach for massive 3D structures. We explore here the potential of the constitutive compatibility method for tackling such an inverse problem, provided an appropriate domain decomposition technique is introduced. In the method described here, the statically admissible stress field that can be related through the known constitutive symmetry to the kinematic observations is sought through minimization of an objective function, which measures the violation of constitutive compatibility. After this stress reconstruction, the local material parameters are identified with the given kinematic observations using the constitutive equation. Here, we first adapt this method to solve 3D identification problems and then implement it within a domain decomposition framework which allows for reduced computational load when handling larger problems.
