TL;DR: In this article, an almost linear dependence of the Vickers hardness on the SiC volume content in the broad range from 7 to 45% was found, and it was shown that the elastic modulus derived from the universal hardness measurements can be successfully used for studying the trend of the elastic properties in functionally graded materials.

TL;DR: In this paper, a series of composites containing additional fillers such as short carbon fibers (SCF), Aramid and polytetrafluoroethylene (PTFE) particles was developed and evaluated in adhesive and low amplitude oscillating wear modes.

TL;DR: In this article, a series of composites with varying amounts of nanoparticles was prepared and their morphology and mechanical properties were studied by tensile tests, dynamic mechanical thermal analysis, and fracture toughness (KIC) investigations; by standardized methods, to define the influence of the nanoparticle content on their mechanical and thermal properties.

TL;DR: The scanning electron microscope pictures of the fracture surfaces of the samples were carried out, which revealed that nanocomposites show a significantly rougher surface than the neat epoxy resin, which indicates a change in the fracture mechanisms.

TL;DR: In this paper, a case study of a journal bearing in pumps, transporting aggressive and abrasive fluids, is presented, where different material compositions were designed and investigated, including epoxy resins, polyetheretherketone (PEEK) matrix, reinforced with short carbon fibres for sealing applications.
