Carbon fibre reinforced plastic (CFRP) laminates are getting more widely used outside the aerospace industry. For large structures the selected process is often vacuum infusion, due to tool cost and heating/pressure limitations for large components. It has also been shown that such process can give sufficient mechanical properties. In the current EUROPE 103-014 project, supported by the Western...

The purpose of this study was to investigate how different materials affect the magnetic resonance imaging (MRI) detectability of interbody test spacers (ITS). We evaluated the post-implantation MRI scans with T1 TSE sequences for three different ITS made of titanium, carbon fibre-reinforced polymers (CFRP) and titanium-coated CFRP, respectively. The main target variables were total artefact vo...

The objective of this study was to investigate the performance pipelines repaired with carbon-fibre-reinforced polymer (CFRP) under external pressure. pipeline experienced defects in terms thinning its local inner wall. three-dimensional finite element method used analyse collapse pressure pipes internal corrosion defects. traction–separation law and interlaminar damage criterion were applied s...

This paper presents the findings of an experimental program aimed at investigating the strain distribution between Carbon Fiber Reinforced Polymer (CFRP) sheets and concrete. CFRP is used as externally bonded reinforcement for concrete structures to improve flexure and shear strength and confinement of concrete. The effects of bonded length, concrete strength, and number of plies (or stiffness)...

This paper investigates the deterioration of reinforced concrete with carbon fiber reinforced polymer (CFRP) anode after polarization. The steel in the concrete was first subjected to accelerated corrosion to various extents. Then, a polarization test was performed with the external attached CFRP as the anode and the steel reinforcement as the cathode. Carbon fiber reinforced mortar and conduct...

This paper gives an intuitive numerical multi-scale method to estimate damping in anisotropic viscoelastic hybrid composite structures using finite element analysis. Different CFRP-R (CFRP with Rubber) architectures, both microstructural and macrostructural, are studied compared order maximize but also minimize rigidity loss. Homogenization by virtual DMA frequency domain is performed on repres...

Thin prepregs with thickness of less than 0.06 mm support flexible lamination design because it is possible to apply various stacking sequences. The objective this study elucidate the effects layer and sequence on open-hole compressive (OHC) strength for thin-ply carbon fiber reinforced plastic composite (CFRP) laminates. Details OHC CFRP laminates were evaluated experimentally. Furthermore, fi...

Guided wave detection using different fiber optic sensors and their applications in damage detection for composite laminates were systematically investigated and compared in this paper. Two types of fiber optic sensors, namely fiber Bragg gratings (FBG) and Doppler effect-based fiber optic (FOD) sensors, were addressed and guided wave detection systems were constructed for both types. Guided wa...

This paper describes fractographic features observed in aerospace composites failed under tensile loads. Unidirectional Carbon Fibre Reinforced Plastic (UD CFRP) and Unidirectional Glass Fibre Reinforced Plastic (UD GFRP) composite specimens were fabricated and tested in tension. The morphology of fractured surfaces was studied at various locations to identify failure mechanism and characterist...
