Intracanal Retention of Glass Fiber Posts
Objective: Fiber-reinforced composite (FRC) posts have recently become more popular for restoring endodontically treated teeth because of providing esthetics, better stress distribution and lower risk of root fracture. Resistance against tensile forces dislodging the post from the root canal is a prerequisite for these posts. This study aimed to evaluate the tensile retention (strength) of in...

متن کاملGlass Fiber and Health Complaints
The term “glass fiber” as used here refers to any rigid, vitreous fiber, mineral or organic. “Glass” is a physically defined state of matter and not a product with a specific chemical composition. To cause health complaints it must be large enough to be trapped by the upper respiratory system. Crystalline fibers, such as the asbestos minerals and other fibrous minerals and vitreous fibers that ...
متن کاملAn Investigation into the Deep Drawing of Fiber-Metal Laminates based on Glass Fiber Reinforced Polypropylene
Abstract Fiber-metal laminates (FMLs) are new type of composite materials which could improve defects of traditional composites in ductility, formability, impact and damage tolerance. Drawing behavior of a thermoplastic based FML was investigated consisting of glass-fiber reinforced polypropylene composite laminate and aluminum AA1200-O as the core and skin layers, respectively. The effects o...
