This article deals with the combined effect of micro and nano fillers on mechanical, thermal and morphological behavior of glass-basalt hybrid composites (GB). Three material systems were selected for the study: glass-basalt fiber reinforced 80 wt. % PA66 – 20 wt. % PTFE blend (GB), GB/Micro fillers (MoS2, SiC, Al2O3) (GBM) and GBM/nano fillers (TiO2) (GBN). It has been revealed from the experimentation that the effect of micro fillers deteriorated the mechanical behavior of micro composites (GBM). But the combined effect of micro and nano fillers slightly impaired the mechanical behavior of nano composites. The synergistic effect of micro and nano fillers constrained the loss of strength of nano composites. But the impact strength of nano composites has been improved due to hybrid fillers effect. The hybrid effect of fillers significantly improved the thermal stability of nano composites. Further, it is observed from the morphology that the fractured surfaces were characterized by fiber pull out and fiber overlapping, severe deformation and agglomeration of nano particles.

Basalt Fibre Reinforced Polymers (BFRP) was feasibly utilized as a preferable replacement to the Glass Fibre Reinforced Polymers (GFRP) due to their superior property and behaviour. Besides, reinforcing nano and micro fillers with basalt fiber will result in even better mechanical properties. In this research study, epoxy resin was blended with Cashew Nut Shell Liquid (CNSL) hardener, it beneficial to minimize the healing period. For 50% of epoxy resin, the ratio of CNSL hardener was taken as 50%. Standard Hand lay-up technique was utilized to produce the composite structures. In addition, 20g of nano and micro fillers were mixed with each epoxy-CNSL proportion. Accordingly, both (SiC & Banana) filler reinforced composites were fabricated and cut to the ASTM standard. Finally, the result of mechanical properties such as flexural and the impact (Charpy) of silicon carbide (SiC) and banana filler reinforced samples were compared.

The Impact

Understanding the damage mechanisms of composite materials requires detailed mapping of the failure behaviour using reliable techniques. This research focuses on an evaluation of the low-velocity falling weight impact damage behaviour of flax-basalt/vinyl ester (VE) hybrid composites. Incident impact energies under three different energy levels (50, 60, and 70 Joules) were employed to cause complete perforation in order to characterise different impact damage parameters, such as energy absorption characteristics, and damage modes and mechanisms. In addition, the water absorption behaviour of flax and flax basalt hybrid composites and its effects on the impact damage performance were also investigated. All the samples subjected to different incident energies were characterised using non-destructive techniques, such as scanning electron microscopy (SEM) and X-ray computed micro-tomography (πCT), to assess the damage mechanisms of studied flax/VE and flax/basalt/VE hybrid composites. The experimental results showed that the basalt hybrid system had a high impact energy and peak load compared to the flax/VE composite without hybridisation, indicating that a hybrid approach is a promising strategy for enhancing the toughness properties of natural fibre composites. The πCT and SEM images revealed that the failure modes observed for flax and flax basalt hybrid composites were a combination of matrix cracking, delamination, fibre breakage, and fibre pull out.

This paper discusses the design of virtual probe tip models for use in a nano-manipulation research test-bed (NMRT). The proposed NMRT would help study the feasibility of a given manipulation technique in a virtual environment before physical experiments. For example, NMRT would be able to help users determine if a specific kind of probe tip can be used to pull out a nano-particle from a given substrate. A virtual probe tip model (for instance) would consider the given geometry and material of probe tip and simulate its behavior in a manipulation application in a physics based virtual reality environment. Such a virtual analysis and overall approach would result in considerable saving in time and financial resources with substantial application potential in medical and biotechnology fields where nanoparticle manipulation is useful. Expandability of the NMRT is made possible by designing an ‘information oriented’ or ‘information intensive’ model for a target set of nano-manipulation activities, which maps in detail various attributes related to a target nano-manipulation process [1]. In this approach, information models based on “engineering Enterprise Modeling Language” (eEML) are used. For example, consider an existing information model for interaction of a probe tip with a spherical particle; a user can use an existing information model, or modify it quickly to study the impact of two approaches (eg. manipulation strategy-A versus strategy-B, which may apply a different probe-tip for gripping). For a target nano-manipulation process (for example, the assembly of nano particles using an Atomic Force Microscope probe as a gripper), an information model can represent the core attributes influencing the target process; influencing criteria including constraints, information inputs, and physical inputs can be modeled explicitly and used to drive a target analysis or simulation activity.

In this study, a new low-velocity shear impact test was introduced to carefully investigate the resistance of 3D E-glass fiber reinforced polymer composites with shear thickening fluid matrix. The shear thickening fluids were prepared by dispersing silica nano-particles in polyethylene glycol. Pure shear thickening fluid was modified by treating the silica surface with (3-Aminopropyl) triethoxysilane. Despite the low-velocity shear impact test, various experimental tests such as yarn pull-out, quasi-static puncture, flexibility and thickness tests were carried out to study the mechanical behavior of the composites. Results revealed the treated shear thickening fluid up to 60 wt% improves the performance of the impregnated samples against the yarn pull-out and puncture tests by 353% and 45%, respectively, and their shear impact resistance by 130% compared to the neat cases without noticeably affecting the fabric flexibility.

The Impact

Natural fiber reinforced polymer composites have become more attractive due to their high specific strength, light weight and environmental concern. However, some limitations such as low modulus and poor moisture resistance were reported. This paper presents the role of halloysite nanotubes (HNTs) on physico-mechanical properties of bidirectional silk and basalt fiber reinforced epoxy (SF-BF/Ep) hybrid composites. Vacuum bagging and ultra-sonication method were used for the fabrication of hybrid composite slabs. The effect of HNT loadings (1.5, 3 and 4.5 wt. %) on physico-mechanical characteristics like density, hardness, flexural and impact properties of SF-BF/Ep composites were determined according to ASTM standards. Experimental results revealed that the incorporation of HNTs improves the mechanical properties. The impact strength of SF-BF/Ep is predominant at 3 wt. % HNT loading where the impact strength surges to 568.67 J/m, which may render HNT filled SF-BF/Ep desirable for various toughness-critical structural applications. The test results demonstrated that SF-BF/Ep-3HNT coded composites exhibited improved mechanical properties among the all composites.

Composite sections have numerous favorable circumstances over unadulterated steel and solid segments. From the past examinations, it has been demonstrated that the yield strain of the high-quality steel is more prominent than a definitive compressive strain of the solid when exposed to stacking. Consequently, this investigation is centered around the impact of early solid pounding on the conduct of the composite sections.In order to maximize the contribution of the concrete to prevent early crushing of the concrete, the concrete reinforced with basalt fiber was considered. In this project, there are twenty one column specimens were casted to study the mechanical behavior in detail. The impact of basalt fiber on the quality and disappointment conduct of composite sections were wanted to explore. For the structure of composite sections, the standard Eurocode-4 plan strategy has been pursued. To ponder the test execution of the proposed composite sections, the two closures with stuck help condition and hub stacking tests were considered

AbstractThe objective of this work lies in the three-dimensional study of the thermo mechanical behavior of a blade of a centrifugal compressor. Numerical modeling is performed on the computational code "ABAQUS" based on the finite element method. The aim is to study the impact of the change of types of blades, which are defined as a function of wheel output angle β2, on the stress fields and displacements coupled with the variation of the temperature.This coupling defines in a realistic way the thermo mechanical behavior of the blade where one can note the important concentrations of stresses and displacements in the different zones of its complex form as well as the effects at the edges. It will then be possible to prevent damage and cracks in the blades of the centrifugal compressor leading to its failure which can be caused by the thermal or mechanical fatigue of the material with which the wheel is manufactured.
