In this study, plasma polymerization technique was used to modify the surface of glass fiber under various plasma powers (30, 60 and 90 W) for exposure time of 15 min to improve the compatibility between glass fiber and epoxy matrix. γ -glycidoxypropyltrimethoxysilane (γ-GPS) monomer were used for surface coating of glass fiber. Interfacial properties of composites were investigated by short be...

The use of fiber-reinforced composite materials has widely spread in various sectors, including aerospace, defense, and civil industry. assessment these heterogeneous material systems is important for safer risk-free applications contributed to the need self-sensing composites. This work focused on development piezoresistive composites, prediction their performance structural health monitoring ...

The effect of polymeric coatings on the static fatigue of double-coated optical fibers is investigated. A closed form solution of the tensile stress in the glass fiber under the action of a constant tensile force in the fiber’s axial direction is obtained using viscoelastic theory. The tensile force is applied to the glass fiber and polymeric coatings. The applied tensile fore is gradually tran...

A novel foaming process-chemical foaming process (CFP)-using foaming agents to fabricate wafer-level micro glass cavities including channels and bubbles was investigated. The process consists of the following steps sequentially: (1) shallow cavities were fabricated by a wet etching on a silicon wafer; (2) powders of a proper foaming agent were placed in a silicon cavity, named 'mother cavity', ...

Abstract An alternative way for increasing the strength of runner’s prosthesis is by utilize direction fiber orientation. The aim this research to determine effect orientation carbon-glass reinforced composite on its bending strength. main materials used in study are carbon and glass fiber. independent variable (0°, 45°, 90°, 0°/90°/0° 90°/0°/90 o) . dependent variables fracture micro photograp...

PURPOSE The aim of this study was to investigate the effect of reinforcing materials on the fracture resistances of glass fiber mesh- and Cr-Co metal mesh-reinforced maxillary complete dentures under fatigue loading. MATERIALS AND METHODS Glass fiber mesh- and Cr-Co mesh-reinforced maxillary complete dentures were fabricated using silicone molds and acrylic resin. A control group was prepared...

The aim of this study was to evaluate the fracture resistance of simulated immature teeth after different intra-radicular treatments. Crowns and roots of bovine incisors were cut transversally and removed to simulate immature teeth. Root canal preparation and flaring were performed using a bur in crown-apex and apex-crown direction. The samples were distributed into 5 groups (n=10): Positive co...
