We present the implementation of aligned carbon nanotubes (CNTs) as a method to enhance properties of traditional advanced composites. The hybrid composites are 3-dimensional architectures of aligned CNTs, and existing advanced fibers and polymeric resins creating nanoengineered composites. Our work to date has focused on interlaminar strength and toughness, and electrical and thermal conductiv...

This clinical report describes the prosthodontic treatment for an 18-year-old man diagnosed with amelogenesis imperfecta. The aim of treatment was to reduce dental sensitivity and to restore esthetics and masticatory function. Metal-ceramic fixed partial dentures were placed on posterior teeth to modify the occlusion, and porcelain laminate veneers were placed to improve the esthetics of the ma...

objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...

The predominant use of FBG sensors to characterize the residual stress state in composite materials date does not permit absolute strain measurements. reason for this is loss connection between sensor and laminate during phase transitions resin. Thus, points significant changes measurement signal (e.g. bonding temperature) need be used evaluation. For fiber metal laminates (FML) however, gages ...

Hybrid laminates, such as fiber metal are increasingly used in engineering applications due to their outstanding damage tolerance and weight-specific performance. Prone vibrations, laminates have recently been complemented by viscoelastic elastomer layers order achieve a desired level of damping following the principles constrained layer damping. This paper presents an analytical modeling appro...

Probabilistic edge-delamination strength of a thermosetting polymer composite was studied experimentally in this work. During the procedure, by means of edge-delamination tensile test, the graphite–fiber/epoxy laminate made of unidirectional Toray P7051S-20Q-1000 prepregs with an optimized lay-up of [122/–122/02]S was used for examining its probabilistic distributions of the edge-delamination o...

Abstract The investigated hybrid carbon fiber reinforced plastics-elastomer-metal laminates (HyCEML) offer the potential of tailored structural materials with adaptable damping properties. Conventional metal laminates, like glass laminate aluminum epoxy are already widely spread in aviation industry owing to their outstanding fatigue behavior. By integrating an elastomeric interlayer, fibers ca...

An attempt is made to analyse the effect of variation in thermal properties in Fibre Metal Laminate with an implanted delamination. This work focuses to explore the variations in thermal contrast for the increase in values of thermal properties of delamination, Aluminium layers and glass reinforced epoxy layers. The paper projects the numerical investigations towards the thermal analysis of fib...
