“…Based on previous studies, numerous thermosettingbased composite systems have been designed and developed using micro size fillers from metal oxides, carbon-based materials to natural fibers [12,13]. It could be consequently understood that the utilization of glass based reinforcements has been widely reported in the enhancement of mechanical properties of composites [14,15]. Although this body of research reveals the dependence of mechanical and physical behavior thermosetting composites reinforced with fillers, the use of the hollow glass microspheres (HGMSs) as lightweight high stiff reinforcements has been rarely reported in respect of the elastic response of polyesterbased composites filled with HGMS as the reinforcement [16].…”

“…The latter is believed to directly affect the strength of interfacial interaction due mainly to the attractive nature of particles when their hydrophobicity differs from that of the parent matrix. Although numerous studies have reported the effect of carbon-based fillers on the mechanical properties of polymeric composites [17,18], less research has been conducted on the correlations among the mechanical behavior and the interfacial interaction at the filler/polymer and in particular in the case of thermosetting composites [19,20].…”

In the micro/nanomaterial reinforced composites, interfacial interactions at the interface of filler/polymer lead to the formation of a third layer called interphase as the secondary reinforcing mechanism. The interphase may be formed due to local adsorption of polymer chains at the interface, mechanical interlocking, and interdiffusion of polymer chains. Since the interactions govern the load transfer at the filler/polymer interface, they play a key role in the mechanical response of reinforced composites. However, there exist only a few well-established and validated studies in the description of the interfacial interactions presented in thermosetting composites. This research aims at the understanding of correlations amongst the mechanical properties of thermosetting polyester composites reinforced with 0-15 wt. % of carbon black (CB) focusing on the nano-size cooperative rearranging region (CRR). To estimate the length of CRR, thermal analysis of the variations in the specific heat capacity or the relaxation strength within the glass transition temperature (Tg) range was measured using a thermodynamic model. A nano-size CRR of 10 nm on average was estimated and correlated to the enhanced impact and toughness behavior of the specimens. The results suggested the presence of softer interphase based on the Tg values influenced by the CBs agglomeration level and cross-linking density, which in turn governs the mechanical response of the composites. The methodology introduced in this study can be used in the explanation of changes in mechanical and physical properties of reinforced composites with a focus on the underlying role of nano-size interfacial interactions.

Purpose. The authors' goal is to determine the behavior of insulated rail joints with polymer-composite fishplates without glueing in the consideration of dynamic loadings regarding to own laboratory tests. In this paper they introduce the applied measurement opportunities. Methodology. Dynamic (fatigue) bending tests were performed by insulated rail joints assembled with plastic-polymer fishplates. The special laboratory measurements are related to digital picture/video measurement technique and assessment method executed by GOM hardware and software, as well as computer tomography according to laboratory bending tests. Findings. In previous papers the authors published the results of glued-insulated rail joints, in this period they continued their research with the investigation of rail joints with plastic-polymer fishplates without glueing. They tested two different types of rail fishplates made of plastic-polymer material. For the rail joints with fishplates but without glueing, the authors applied special measurement techniques by GOM products (Tritop, Aramis) that enable high precision digital measurement techniques with spectacular visualization results. The computer tomography records ensure the opportunity to be able to receive information about inner crackings and faults of plastic-polymer fishplates, with also high precision measurements. The assessment method has to be developed for these specific measurement methodologies to be able to compare the results and define scientific statements. Originality. Up to now any researcher and research group have been dealing with insulated rail joints with special plastic-polymer fishplates without glueing applied mentioned special techniques, no one determined the exact deterioration process of these joints, as well as the crack growing phenomenon in the cross section of the fishplates. Practical value. The research team of the authors had the possibility to see into the details of glass-fibre reinforced resin bonded plastic fishplates during laboratory tests, as well as they publish timely information in the consideration of their laboratory tests' results. This result can be applied in railway engineering at all stages: design, construction, maintenance&operation in the future.
