Analysis of Tensile Strength on Various Layer Stack Sequence of Fiber Reinforced Polymer (FRP)

Journal of Sustainable Civil Engineering and Technology, 2022
This paper presents the analysis of tensile strength on various layer stack sequence of Fiber Reinforced Polymer (FRP). FRP is a composite material which made of hardened or room temperature treated resin as medium. The FRP is composed with particular reinforcement materials in order to evaluate the strength.

Damage mechanics approach to nonlinear behavior of FRP laminates with cracking layers

Advanced Composite Materials, 1999
A damage mechanics model to predict the nonlinear behavior of laminated composites due to crack evolution is developed. We propose a new concept that a cracking layer can be replaced with an equivalent uniform work-softening layer. With this new concept, the constitutive equations for a cracking layer are constructed according to modem plasticity ...

Compression behavior and modeling of FRP-confined high strength geopolymer concrete

, 2021
Fiber-reinforced polymer (FRP) has proven its efficiency as a strengthening material of ordinary concrete. However, the research on the effect of these materials on geopolymer concrete is still less understood.

The effect of the number of strengthening layers on the FRP-concrete bond behaviour

European Journal of Environmental and Civil engineering, 2011
ABSTRACT Bonding is a very important issue when Fiber Reinforced Composites (FRP) are used to strengthen reinforced concrete beams. Bonding depends on the mechanical and physical properties of concrete, composite and adhesive. A number of studies have been published concerning the investigation of the relationship between these aspects and the ultimate

Experimental investigations on corrosion resistance of innovative steel-FRP composite bars using X-ray microcomputed tomography

Composites Part B: Engineering, 2019
A steel-fiber reinforced polymer (FRP) composite bar (SFCB) is a new type of hybrid bar consisting of a steel core and an FRP shell coating. The advantages of the two materials are complementary.

Remote sensing of air blisters in concrete?FRP bond layer using IR thermography

International Journal of Materials and Product Technology, 2003
Studies have been conducted to: (a) detect artificially induced blisters in the bond-line between FRP components and the RC beams and (b) evaluate the influence of air-voids on the flexural performance of FRP strengthened RC elements. The air-voids were introduced within the bond-line of the concrete elements and the reinforcing FRP.
