ABSTRACT: This paper explores the behavior of infill masonry structures strengthened with a new type of Fiber Reinforced Polymer (FRP) strengthening system with high fracture strain know as PET (Polyethylene Teraphthalate) and a new near-surface mounted (NSM) Carbon fiber strengthening system using a cementitious material as the adhesive as compared to a Glass Fiber (GFRP) strengthening system ...

The efficient use of fiber reinforced polymer matrix composites in load-carrying structures requires detailed analyses to assess their mechanical performance, cost, and weight saving aspects. To accurately analyze the cyclic fatigue life of composite laminates, the influence of the physical non-linearity of the unidirectional lamina in the cyclic fatigue life analysis was examined using enhance...

Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coated nickel-titanium (NiTi) and esthetic archwires combined with ceramic brackets. Material and Method...

Kenaf (Hibiscus Cannabinus) fibers have received significant attention for replacing the usage of synthetic fibers, especially glass fiber, in fabrication fiber-reinforced polymer (FRP) composites. The aim this research was to study change wear behavior kenaf-epoxy fiber composites by filling them with multiwall carbon nanotubes (MWCNT). In particular, effect untreated MWCNT (PMWCNT), acid-trea...

A Model to Predict the Long-Term Strength of E-Glass Fiber Composites Subjected to Environmental Exposure Thomas Miles Damiani Glass Fiber Reinforced Plastics (FRP) are being used in an increasing number of structures and machines because of their advantages over conventional materials such as steel or aluminum. However, sustained exposure to seemingly nominal service conditions can act to degr...

Several building codes are available for the design of concrete structures reinforced with FRP; nevertheless knowledge on their structural behavior in case of fire is lack and no reliable design method is available. The experimental data available in the literature about the behavior of fiber-reinforced composite materials as well as of concrete slabs reinforced with FRP bars or grids at high t...

Since the development of carbon nanotubes (CNTs) in 1991, they have received much attention with improved mechanical, thermal, and electrical properties of their composites compared to common polymer composites. The CNTs are currently used to increase the modulus of common thermoplastics and thermosets, including urethanes and epoxies. The CNTs are difficult to disperse within any media because...

Composite resins were reinforced with glass and polyethylene fibers in this study, and the effect of fiber reinforcement on the color change of composite resins was investigated. After accelerated aging, the effect of fiber reinforcement on the color stability of composite resins was also examined. There were three experimental groups (n=12 disks per group): non-fiber-reinforced composite (non-...

Lightweight design, using high performance composites, which directly yields a reduced need for fuel is in the focus of new developments for traffic engineering. The increased substitution of traditional, metal based materials by fibre-reinforced composites in the aviation industry exemplifies this trend. In addition to mechanical properties, e.g. an increase in strength, that leads to direct w...

This review paper reported carbon nanotubes reinforced composites for biomedical applications. Several studies have found enhancement in the mechanical properties of CNTs-based reinforced composites by the addition of CNTs. CNTs reinforced composites have been intensively investigated for many aspects of life, especially being made for biomedical applications. The review introduced fabrication ...
