Design optimization of a CFRP-aluminum joint for a bioengineering application

John Botsis, Georgios Pappas

Lightweight design demands and complexity requirements of modern high-end structures in aerospace, automotive, sports and bioengineering can be successfully covered by a combination of fiber reinforced polymers (FRPs) with metallic components. Conventional ...

Bond Behavior of CFRP Sheets Attached to Concrete through EBR and EBROG Joints Subject to Mixed-Mode I/II Loading

Ardalan Hosseini

The bond behavior of carbon fiber–reinforced polymer (CFRP) sheets attached to concrete surface subject to mixed-mode I/II loading through single lap-shear tests is assessed. A 63 concrete prism specimens of 150 × 150 × 330 mm were prepared through externa ...

Probing the micromechanical strength of oxide ceramic composite reinforcements

Václav Pejchal

This work shows how one can probe the micromechanical strength of ceramic reinforcements used in metal matrix composites, which greatly influences the mechanical performance of the composite material yet has seldom been quantified with precision. More spec ...

Stress Analysis of Unbonded and Bonded Prestressed CFRP-strengthened Steel Plates

Alain Nussbaumer, Elyas Ghafoori, Masoud Motavalli, Ardalan Hosseini

Numerous research studies are available in the literature on strengthening of steel members using carbon fiber reinforced polymer (CFRP) composites. Although it is clear that strengthening using prestressed CFRP plates has several advantages over non-prest ...

Determination of minimum CFRP pre-stress levels for fatigue crack prevention in retrofitted metallic beams

Alain Nussbaumer, Elyas Ghafoori, Gary Scott Prinz, Andrin Herwig

The majority of fatigue strengthening studies focus on reducing propagation rates of existing cracks, ignoring the crack initiation stage. Many existing metallic bridge members however do not contain existing cracks, but rather are nearing their design fat ...

A Novel Structural Health Monitoring Method for Full-Scale CFRP Structures

Enrique René Guzman Solares

Polymer-based composite materials are used to manufacture ultra-light panels, massively introduced in the last decades in the aeronautical industry, as a potential solution to reduce the energy consumption and combustion emissions. Safety being the main co ...

Multi-factorial models of a carbon fibre/epoxy composite subjected to accelerated environmental ageing

Thomas Gmür, Joël Cugnoni, Enrique René Guzman Solares

Among materials being introduced in the aerospace industry, the carbon fibre reinforced plastics (CFRP) have a place of privilege because of their exceptional stiffness-to-mass ratio. However, the polymer-based matrix is vulnerable to damages by environmen ...

Carbon Fiber-Reinforced Polymer Punching Reinforcement and Strengthening of Concrete Flat Slabs

Thomas Keller, Robert Koppitz

Three different carbon fiber-reinforced polymer (CFRP) systems were used to reinforce new or strengthen existing concrete slabs against punching. Untensioned CFRP plates or only very low prestressed CFRP straps could not prevent brittle punching failure. S ...

Carbon Fibre Reinforced Composite Waste: An Environmental Assessment Of Recycling, Energy Recovery And Landfilling

Jan-Anders Edvin Maansson, Véronique Michaud, Christian Ludwig, Robert Andrew Witik

The environmental benefits of recycling are assessed against other end-of-life (EOL) treatments for Carbon Fibre Reinforced Plastic (CFRP) waste. Recycling via pyrolysis, incineration with energy recovery, and disposal via landfilling are compared. To acco ...

An analysis of destination choice for opaque airline products using multidimensional binary logit models

Michel Bierlaire

We investigate how customers respond to an opaque airline product offered by a European carrier. In this opaque product design, customers are randomly assigned to travel to one of approximately ten destinations; however, for a fee they may exclude one or m ...
