page 62 Abstract: A fiber pullout test for examining controlled interfaces in fiber reinforced polymers has been designed and demonstrated. This test has been utilized in determining interfacial fracture toughness for sapphire/epoxy single fiber composite specimens. Some of these specimens incorporated a self-assembled monolayer at the sapphire/ epoxy interface as a means of adhesion control—th...

in this paper, using numerical methods and test results, the behavior of reinforced concrete beams strengthened with fiber-reinforced polymers (frp) is investigated. in the numerical analysis, the concrete damaged plasticity model is used for considering the nonlinear behavior and strain softening of concrete. the abaqus finite element program is utilized for the analysis of 12 flexural beams s...

This study focuses on the optimizing the microstructure to improve the efficiency for healing interfacial debonding in fiber-reinforced polymers (FRPs). Healing is accomplished by incorporating a microcapsulated healing agent and catalytic chemical trigger within a coating layer on the surface of the fiber strands. Self-healing is demonstrated on flat tensile specimens of unidirectional FRPs. T...

Timber, concrete and steel are among the traditional building materials used in construction of buildings. Since is a durable material, it material buildings, highways, dams, sidewalks many other areas. Wood one oldest materials, use wood wood-based for structural purposes continues to increase. The deterioration existing wooden structures may result from fatigue biological attack over time. co...

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...

This article is a survey discussing the application of fiber-reinforced polymer composites in freeform structures and their impact on design shape generation process. The analysis case studies showed that use FRP not only helps to overcome some challenges construction objects with complex geometry, but also creates brand new types approaches. On other hand, there problem—although materials are ...

Carbon fibers reinforced polymers (CFRPs) are prolifically finding applications in the medical field, moving beyond aerospace and automotive industries. Owing to its high strength-to-weight ratio, lightness radiolucency, CFRP-based materials emerging replace traditional metal-based implants. Numerous types of matrices can be incorporated with carbon fiber using various manufacturing methods, cr...

Objective. The aim of this study was to evaluate the effect of incorporation of glass fiber, zirconia, and nano-zirconia on the transverse strength of repaired denture base. Materials and Methods. Eighty specimens of heat polymerized acrylic resin were prepared and randomly divided into eight groups (n = 10): one intact group (control) and seven repaired groups. One group was repaired with auto...
