Enhanced dynamic mechanical properties of different-structured nanoclays incorporated BFRP based on “stick-slip” hypothesis

Abstract

The natural nanoclays and basalt fibers are attracting a considerable amount of interest due to their outstanding properties. Halloysite nanotubes (HNTs) incorporated basalt fiber reinforced polymers (BFRPs) exhibit promising potential applications in marine industries, such as offshore oil platforms and pipelines, due to their high mechanical strength and robust chemical durability. However, their damping capability, which is of great importance for large structural component applications, has not been yet thoroughly investigated. The main goal of this study is to investigate the damping property of nanoclays incorporated BFRPs, by combining the experimental patterns with the respective computational insights. Multiple-structured nanoclays were successfully synthesized by following various experimental approaches. The “stick-slip” mechanical model was implemented in order to elaborate on the energy dissipation issue, due to the development of interfacial frictional slip, whereas the experimental outcome was compared with the respective computational results in order to test the validity of our theoretical approach. Along these lines, the dynamic properties obtained by experimental analysis divulged a fair degree of agreement with the computational results. The fabrication of composites by incorporating HNTs with moderate aspect-ratio value and interfacial bonding can be considered as a quite promising solution in improving the energy dissipation performance.
