The use of mechanically-fastened fiber-reinforced polymer (MF-FRP) systems has recently emerged as a competitive solution for the flexural strengthening of reinforced concrete (RC) beams and slabs. An overview of the experimental research has proven the effectiveness and the potentiality of the MF-FRP technique which is particularly suitable for emergency repairs or when the speed of installati...

Abstract Fiber-reinforced polymer (FRP) strengthening and retro fi tting of concrete elements, such as beams, columns, slabs, and bridge decks, have become increasingly popular. Nonetheless, rapid and reliable nondestructive testing techniques (NDT) that are capable of remotely assessing in-situ integrity of retro fi tted systems are needed. Development of a robust NDT method that provides an a...

Fiber reinforced polymer (FRP) laminates are being used as external reinforcement for strengthening concrete members. The performance of unidirectional FRP laminates is highly dependent on fiber orientation with respect to applied load direction. In the case of fabrication by manual lay-up, it is possible to have fiber plies installed with improper orientation. In this project, the degradation ...

Shell-rib structures made of textile-reinforced composites are used in a wide range applications to increase bending, buckling and torsional stiffness. Such usually manufactured differential construction at the preform level by assembling several textile or component subsequent joining separately shells stiffening structures. Integral production is one way overcome disadvantages forenamed metho...

Fiber-reinforced polymer (FRP) composites have gradually gained wide acceptance as engineering material applications due to their unique advantages including high strength-to-weight ratio and excellent corrosion resistance. This study was carried out with prepared by hot press molding method using coconut spathe fiber reinforcing HDPE (from can obsolete polymer) matrix. Composites were made at ...

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 paper describes an innovative alternative to manual procedures for the application of carbon fiber and resin injection in concrete surfaces in tunnels. It is based on a specially designed light-weight integrated tool for automatic application of Fiber Reinforced Polymer (FRP) and epoxy resin injection. Vision and laser telemeter sensing are integrated into the tool to assure precise inspec...

objective : the aim of this study was to evaluate fracture characteristics of rigid two-tooth segments splinted with fiber reinforced composite (frc), with and without application of simulated masticatory forces. material and methods: in this experimental study, 80 extracted maxillary bicuspids were joined in pairs from the buccal aspect using frc. the specimens were divided into two groups. in...
