Behavior of prestressed CFRP plates bonded to steel substrate: numerical modeling and experimental validation

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In recent years, retrofitting of steel structures has emerged as a major issue in structural engineering and construction management. As the adhesive bond is often the critical aspect controlling the actual performance of steel profiles externally strength ...

Studies on Traction Separation Relations in Fracture of Layered Composites

Georgios Pappas

Layered fiber reinforced composite materials are prone to fracture in planes parallel to the direction of fibers leading to extensive delamination or intralaminar fracture. This phenomenon of crack propagation is frequently accompanied by significant incre ...

Strong particles in Metal

Andreas Mortensen, Marco Cantoni, Goran Zagar, Raphaël Charvet, Cyril Dénéréaz, Martin Guillermo Mueller, Václav Pejchal, Marta Fornabaio, Lionel Michelet, Willy Dufour

We all know that strong fibers make most of today¹s composite materials what they are : exceptionally stiff, strong, light and tough materials that serve in a number of demanding structural applications. This presentation will try to make the case for stro ...

Aramid/glass fiber-reinforced thermal break - thermal and structural performance

Thomas Keller, Julia De Castro San Roman Fest, Kyriaki Goulouti

Energetically weak points in thermally insulated building envelopes are formed by thermal breaks that are implemented to structurally connect external balconies to internal slabs. Current thermal breaks comprise stainless steel bars that penetrate the insu ...

Temperature effects on material properties and structural response of polymer matrix composites

Wei Sun

Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...

Processing of Sustainable Cellular Biocomposites

Carole Boissard

Petroleum-based polymers and composites are commonly used in a wide variety of application fields. However ecological concerns, increasing oil prices and dwindling natural resources explain why nowadays industrial and public interest is more than ever focu ...

EPFL2012

Nowadays, composite materials are increasingly used in high technology fields such as aerospace and automotive because of the combination of excellent mechanical performance and lightweight. For these characteristics, classical metal alloys are progressive ...
