This contribution is focussing on the application of visual elements in the process of creating composite structure with the use of technique hand lay-up Pre-preg. In this method the crucial factor is not only to specify the exact position of the applied layers but the important factor as well is the right order and orientation of individual layers which are determining the strength characteris...
In this research, the numerical and experimental analysis of the carbon fiber composite lattice conical structure has been performed to assess the buckling stability of the structure before and after the lateral impact. In the experimental analysis, the carbon fiber composite lattice conical structure was constructed with the winding method and using elastic molds and metal mandrel. In or...
The pair distribution function and the static structure factor are computed for composite fermions. Clear and robust evidence for a 2kF structure is seen in a range of filling factors in the vicinity of the half-filled Landau level. Surprisingly, it is found that filled Landau levels of composite fermions, i.e. incompressible FQHE states, bear a stronger resemblance to a Fermi sea than do fille...
The composite metal oxide electrode films were fabricated using ex situ electrodeposition method with further heating treatment at 300°C. The obtained composite metal oxide film had a spherical structure with mass loading from 0.13 to 0.21 mg cm(-2). The structure and elements of the composite was investigated using X-ray diffraction (XRD) and energy dispersive X-ray (EDX). The electrochemical ...
Composite coiled tubing is an emerging technology in the oil & gas sector that presents important advantages compared to the steel coiled tubing and conventional drilling. The composite tube has reduced weight, allowing extended reach and improved fatigue life. An additional advantage resides in the fact that the coiled tube wall can contain and protect additional functional elements, such as e...
In this study, a novel visible-light-sensitive Bi2WO6/BiVO4 composite photocatalyst was controllably synthesized through a facile one-pot hydrothermal method. The Bi2WO6/BiVO4 composite exhibited a perfect nest-like hierarchical microsphere structure, which was constructed by the self-assembly of nanoplates with the assistance of polyvinylpyrrolidone (PVP). The growth mechanism of the Bi2WO6/Bi...
In this paper, we describe our experience in using the RM-ODP to specify composite objects. The concept of a composite object as defined in RM-ODP does not take into account its dynamic structure as well as the classification of its properties into inherent, aggregate and emergent properties. To make this possible, we have to complement the description of composite objects with explicit contrac...
The aim of this paper is to introduce a method for creating a homogenous substitute material for composite materials using optimisation algorithms. Composite materials are modern construction materials used, for example, in aircraft construction. However, numerical modelling of these materials is, due to its multi-layer structure, very difficult to compute. This multi-layer structure and loss m...
Over the past few decades, there has been a considerable interest in the use of distributed optical fibre sensors (DOFS) for structural health monitoring of composite structures. In aerospace-related work, health monitoring of the adhesive joints of composites has become more significant, as they can suffer from cracking and delamination, which can have a significant impact on the integrity of ...
Magnetoresistive memory is a candidate for future universal memory because of fast switching, high density, and non-volatility. However, improvement regarding the essential parameters such as thermal stability and switching current is still needed and finding alternative architectures for magnetic cell structures is of considerable importance for the success of magnetoresistive memory. A struct...
