Debonding of CFRP-to-steel joints with CFRP delamination
Composite Structures, 2016Abstract Extensive experiments were conducted to investigate the bond characteristics of CFRP-to-steel joints on cohesive failure, which is considered as the ideal failure mode. In this present article, the main aim is to demonstrate the rationality of CFRP delamination and to provide a detailed understanding of bond characteristics on delamination ...

3D-reinforcement techniques for co-bonded CFRP/CFRP and CFRP/metal joints: a brief review
Ciência & Tecnologia dos Materiais, 2017Abstract The present paper will make a brief review on some of the most relevant through-thickness reinforcement technologies for CFRP/Metal and CFRP/CFRP joints developed so far. A distinction between the traditional (“ z-pinning ” and “ stitching and tufting ”) and novel (“ COMELD TM ”, “ CMT ”, “ HYPER ” and “ RHEA ”) 3D-reinforcement ...

A signal segmentation method for CFRP/CFRP stacks drilling-countersinking monitoring
Mechanical Systems and Signal Processing, 2023Carbon-fiber-reinforced plastics (CFRP) stacks are widely used in the aerospace industry owing to their superior mechanical properties and lightweight nature. In this industry, CFRP/CFRP stacks are often drilled and countersunk to create holes for assembly fasteners.

Some effects of moisture on adhesive-bonded CFRP-CFRP joints
Composite Structures, 1986Abstract Investigations have been carried out into the effect of long-term exposure to a hot, humid environment on the strength and mode of failure of CFRP-CFRP joints bonded with structural epoxy adhesives. Strengths of joints have been shown to be reduced both by absorption of moisture and by increased test temperature. There is some evidence that,

A Comparative Study of Carbide Tools in Drilling of CFRP and CFRP-Ti Stacks
Journal of Manufacturing Science and Engineering, 2013A comparative study was conducted to investigate the resulting tool wear and hole quality when drilling the stacks made of titanium (Ti) and carbon-fiber reinforced plastic (CFRP) versus CFRP only plate using micrograin tungsten carbide (WC) twist drills. The experiments were designed to first drill CFRP alone to create 20 holes.

A Comparative Study of Carbide Tools in Drilling of CFRP and CFRP-Ti Stacks
ASME 2011 International Manufacturing Science and Engineering Conference, Volume 1, 2011A comparative study was conducted to investigate drilling of a titanium (Ti) plate stacked on a carbon fiber reinforced plastic panel. The effects on tool wear and hole quality in drilling using micrograin tungsten carbide (WC) tools were analyzed. The experiments were designed to first drill CFRP alone to create 20 holes.

Prestressing with CFRP Tendons
High Performance Materials in Bridges, 2003Considerable corrosion of reinforced concrete members accelerated the research on non-metallic materials such as fiber reinforced polymers (FRP) for structural applications in non-corrosive reinforcement. This paper describes a comparative experimental study that was performed on prestressed concrete beams pretensioned with carbon-FRP or steel wires ...

Hysteresis behaviour during tensile microstrain and constant amplitude load cycling has been studied with CFRP of approximately 50% fibre volume fraction. This hysteresis is explained in terms of the residual strain in the composite caused by the different thermal expansion coefficients of the fibre and matrix. The energy loss during cyclic deformation
