Durability Prediction of GFRP Rebar Based on Elastic Modulus Degradation

open access: yesFrontiers in Materials, 2019
A conventional method to study the durability of Glass Fiber Reinforced Polymer (GFRP) rebars is to carry out tensile tests on the corroded GFRP bars.

Effects of nano-SiO2 on mechanical and hygric behaviors of glass fiber reinforced epoxy composites

open access: yesScience and Engineering of Composite Materials, 2018
The unmodified and nano-SiO2 modified glass fiber reinforced polymer (GFRP) composites were prepared by the hot-compression molding process to investigate the effects of nano-SiO2 on the mechanical and hygric properties of the GFRP composites.

A Quantitative Study on the Void Defects Evolving into Damage in Wind Turbine Blade Based on Internal Energy Storage

open access: yesApplied Sciences, 2020
As manufacturing defects, voids in wind turbine blades may cause damage under fatigue loads. In this paper, the internal energy storage is used as an indicator to identify the critical moment when a defect evolves into damage.

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]

open access: yes, 2014
An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...

Flexural Response of RC beams cast with normal and steel fibre concrete internally reinforced with various types of FRP bars

open access: yesGrađevinar, 2021
Fibre Reinforced Polymer (FRP) bars can be used as an alternate for reinforcing bars to avoid corrosion of steel. Samples of reinforced concrete beams cast with normal or steel fibre concrete (SFC), internally reinforced with Glass Fibre Reinforced ...

Flexural Behavior of UHPC Beams Reinforced with Macro-Steel Fibers and Different Ratios of Steel and GFRP Bars [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering
The flexural and shear behavior of ultra-high-performance fiber-reinforced concrete (UHPFRC) reinforced with different ratios of glass-fiber-reinforced polymer (GFRP) and conventional steel rebars is experimentally studied in this paper. For this purpose,

Damage Monitoring of CP-GFRP/GFRP Composites by Measuring Electrical Resistance [PDF]

open access: yesKorean Journal of Materials Research, 2010
Abstract It is necessary to develop new methods to prevent catastrophic failure of structural material in order to avoidaccidents and conserve natural and energy resources. Design of intelligent materials with a self-diagnosing function toprevent fatal fracture of structural materials was achieved by smart composites consisting of carbon fiber tows or ...

Comparison of Fatigue Tensile Properties of Scrimp-Gfrp and Hlup-Gfrp

open access: yesJournal of Mechanics, 2008
AbstractSeemann Composites Resin Infusion Molding Process (called SCRIMPTM for short) is a resin transfer molding process which is commonly used in the manufacture of yachts. Fiber-Reinforced Plastic (called FRP for short) manufactured by using SCRIMP has higher fiber-volume-content than that manufactured by using Hand Lay-Up Process (called HLUP for ...
