Abstract In this study, structurally efficient carbon fiber reinforced plastic (CFRP) sandwiches were developed via introducing pumice/Mg composite foams as new core material. The effects of the direction (0°, 45°, 90°) on mechanical properties CFRP laminates and studied. Compared with 45°-CFRP 90°-CFRP laminates, 0°-CFRP laminate exhibits outstanding flexural due to different failure modes. Co...

Porosity is a result of a deficiency in the production process that could lead into the mechanical degradation of CFRP composite structures. Therefore, some checkpoints for determining its presence during part manufacturing have to be established, verifying that precise threshold values are not exceeded. Currently, porosity characterization is carried out by an indirect way using ultrasonic tec...

Introduction: Carbon fibre-reinforced polymers (CFRP) are being investigated for the next generation of arthroplastic devices. Their mechanical similarities with bone make them ideal for load bearing implants. Previous attempts at using CFRP have failed due to the lack of osseointegration with bone. Treatments to increase surface roughness and topography have shown to affect the attachment and ...

This paper presents results from Finite Element Modelling (FEM) of steel-concrete composite beams strengthened with prestressed Carbon Fibre Reinforced Polymer (CFRP) plate. For the purpose of this study, three beams were strengthened using prestressed CFRP plate with three different levels of induced prestressing force. The models were developed using ANSYS FE package. The results of an experi...

This paper presents an elastic shear stress distribution theoretical model at the carbon fiber-reinforced polymer (CFRP)-adhesive interface of a single-rod and a multi-rod straight-pipe bonding anchor. A comparison between theoretical and finite element analysis results reveals that the accuracy of the theory can be used to guide the preliminary design of CFRP rod bonding anchors. The mechanica...
