OBJECTIVE In our previous study, glass-fiber-reinforced plastics (GFRPs) made from polycarbonate and glass fibers were prepared for esthetic orthodontic wires using pultrusion. These laboratory GFRP wires are more transparent than the commercially available nickel-titanium wire; however, an investigation of the color stability of GFRP during orthodontic treatment is needed. Accordingly, in the ...

background : denture fracture is an unresolved problem in complete denture prosthodontics. however, the repaired denture often experiences a refracture at the repaired site due to poor transverse strength. hence, this study was conducted to evaluate the effect of joint surface contoursand glass fiber reinforcement on the transverse strength of repaired acrylic resins. materials and methods: a t...

In this paper the effect of various chemical treatments on the damping property of jute fiber reinforced green composite is discussed. The surface of the jute fiber was modified by alkali, permanganate, benzoyl chloride, malic anhydride and silane treatments. Several samples of unidirectional composites were prepared with treated jute fibers as well as untreated jute fibers. Matrix used is epox...

Carbon fiber-reinforced particulate composites are immensely used in commercial and military applications due to their excellent functional mechanical performance. Several studies have been reported use nanofiller carbon improve However, a comparative study was required depict the best dielectric magnetic nanofillers with The current research performed compare effect of different nanoparticles ...

In this paper, interphases in unidirectional fiber-reinforced composites under transverse loading are modeled by an advanced boundary element method based on the elasticity theory. The interphases are regarded as elastic layers between the fiber and matrix, as opposed to the spring-like models in the boundary element method literature. Both cylinder and square unit cell models of the fiber-inte...

AIM To compare the effect of different chemical solvents on glass fiber reinforced posts and to study the effect of these solvents on the shear bond strength of glass fiber reinforced post to core material. MATERIALS AND METHODS This study was conducted to evaluate the effect of three chemical solvents, i.e. silane coupling agent, 6% H2O2 and 37% phosphoric acid on the shear bond strength of ...

This study compared the initial and final failure loads and failure modes of indirect resin composite laminate veneers with and without fiber reinforcement. Forty intact lower canines received standard laminate preparations and were randomly assigned into four test groups (n=10). In Group 1, indirect resin composite veneers were repaired with two layers of preimpregnated bidirectional glass fib...
