The complex mechanical behaviour of composite materials, due to internal heterogeneity and multi-layered composition impose deeper studies. This paper presents an experimental investigation technique to perform volume kinematic measurements in composite materials. The association of X-ray micro-computed tomography acquisitions and Digital Volume Correlation (DVC) technique allows the measuremen...

Composite materials have attracted much interest because of the emergent properties originating from the components. A variety of methods have been studied to control the morphology of composites based on noncrystalline polymers and crystalline materials. However, it is not easy to control complex morphologies, such as segregated sea-island structures, on the submicrometer scale. Polymerization...

This paper presents an overview of manufacturing, static/dynamic test and validation work carried out on composite rail vehicle structures. Two case studies, detailing the development and experimental validation of a composite bodied people mover and a foam core composite roof for a regional train are presented, demonstrating new and novel applications of composite materials within the rail ind...

The increasing demand for in-service structural health monitoring, particularly in the aircraft industry, has stimulated efforts to integrate self sensing capabilities into materials and structures. This work presents efforts to develop structural composite materials which include networks of sensors with decision-making capabilities that extend the functionality of the composite materials to b...

The aim of the research was: the scientific justification and development of non-destructive testing system of products made of composite materials using low-frequency acoustic methods. During the work the following problems have been pointed and solved: 1. Analysis of the statistical characteristics of information signals and forming a set of diagnostic parameters. 2. Justification of necessit...

Wear of restorative materials has been characterized in vitro using single-pass sliding.'4 Wear patterns and surface structures of composite restorations in vivo have been reported by Kusy and Leinfelder5 and by O'Brien and Yee.6 However, there have been few reports on the correlation between in vitro and in vivo wear. One reason could be that the in vivo wear characteristics result from gradua...

Free-radical polymerization inside mesoporous silica has been investigated in order to open a route to functional polymer-silica composite materials with well-defined mesoporosity. Various vinyl monomers, such as styrene, chloromethyl styrene, 2-hydroxyethyl methacrylate, and methacrylic acid, were polymerized after impregnation into mesoporous silicas with various structures, which were synthe...

Composite materials are being widely used in applications including marine industry where specific properties and corrosion resistance are required. Many applications have been mentioned for pipes systems on ships, offshore platforms and also for coastal engineering plant such as power stations and desalination installations. However, it was recognized that the optimum use of composite material...

Molecularly imprinted nanoparticles were encapsulated into polymer nanofibers with a simple electrospinning method. The composite nanofibers form non-woven mats that can be used as affinity membrane to greatly simplify solid phase extraction of drug residues in analytical samples. Upward 100% of propranolol-imprinted nanoparticles can be easily encapsulated into poly(ethylene terephthalate) nan...

OBJECTIVES To investigate the influence of pre-heating of high-viscosity bulk-fill composite materials on their degree of conversion and shrinkage force formation. METHODS Four bulk-fill composite materials (Tetric EvoCeram Bulk Fill-TECBF, x-tra fil-XF, QuixFil-QF, SonicFill-SF) and one conventional nano-hybrid resin composite (Tetric EvoCeram-TEC) were used. The test materials were either k...
