Journal ArticleDOI
Mechanical performance evolution and life prediction of prestressed CFRP plate exposed to hygrothermal and freeze-thaw environments
TL;DR: In this article , a wedge-extrusion bond anchorage system was applied to provide the reliable anchorage load-bearing capacity for CFRP plate, and a new prestressed tension device was put forward to realize the coupling exposure of elevated temperature (20 °C, 60 °C and −20 to 30 °C), distilled water and sustained loading (20, 40% and 60%).
Journal ArticleDOI
Long-term service evaluation of a pultruded carbon/glass hybrid rod exposed to elevated temperature, hydraulic pressure and fatigue load coupling
TL;DR: In this article, a pultruded glass fiber shell (GFS) and carbon fiber core (CFC) hybrid rod (HFRP) with the diameter of 19mm was exposed in an underground oil well.
Journal ArticleDOI
Mechanical property evolution and service life prediction of pultruded carbon/glass hybrid rod exposed in harsh oil-well condition
TL;DR: In this paper, the degradation mechanism of HFRP rods was attributed to plenty of bound water combined with the resin through the hydrogen bond and brought about the hydrolysis of resin and the increase of pore volume content, leading to the debonding of fiber/resin.
Journal ArticleDOI
Hygrothermal resistance of pultruded carbon, glass and carbon/glass hybrid fiber reinforced epoxy composites
TL;DR: In this article, the hygrothermal properties of pultruded carbon, glass and carbon/glass hybrid fiber reinforced polymer composite plates were investigated experimentally through the immersion in deionized water at 40°C, 60°C and 80°C as long as 135 days.
Journal ArticleDOI
Innovative compound-type anchorage system for a large-diameter pultruded carbon/glass hybrid rod for bridge cable
TL;DR: In this article, a hybrid fiber reinforced polymer (HFRP) composite rod was developed as the bridge stay cable through the pultrusion technology with the diameter of 19 mm, including carbon fibre reinforced polymer core (CFC) and glass fiber reinforced composite shell (GFS), and a simplified mechanical model based on equilibrium, geometric and physical equations and finite element analysis were conducted to analyze the potential failure modes of anchoring HFRP rods.
