2. 1. Behaviour and design of adhesive joints in flexural steel members bonded with FRP laminates

   Author : Reza Haghani Dogaheh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; Adhesive joint; Stress concentration; FRP; Design; Optic measurement; Fillet; Tapering;

   Abstract : The use of bonded CFRP laminates to strengthen and upgrade existing structures has attracted a great deal of attention during the past two decades. The superior mechanical properties of CFRP laminates, such as high strength and stiffness, excellent fatigue properties and good durability characteristics, have made them a suitable alternative to steel plates used in traditional strengthening and repair methods.

4. 2. Comparison of operational limit estimations for FRP laminates – effects of material modelling and stochastic behaviour

   Author : Luis Felipe Sanchez Heres; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety.; FRP; reliability; probability;

   Abstract : Transport companies need vehicles with higher efficiency to remain competitive and comply with environmental regulations. Lightweight construction is one way to increase the efficiency of a vehicle. In some vehicles, lightweight construction can reduce the fuel consumption, increase the cargo capacity and reduce the environmental footprint. READ MORE

5. 3. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

   Author : Valbona Mara; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

   Abstract : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. READ MORE

6. 4. Influence of liquid diffusion on the performance of polymer materials in industrial applications

   Author : Stefanie Römhild; Mikael Hedenqvist; Lars Berglund; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LCP; Vectra A950; thermoset resin; FRP; diffusion; disclination; annealing; lining; bonding; long-term properties in water; Polymer chemistry; Polymerkemi;

   Abstract : Diffusion of liquids into and through polymers is an important factor that negatively may influence the durability or lifetime of a polymer structure used in industrial applications. In this work two types of polymers, a liquid crystalline polymer (LCP, Vectra A950) and various thermoset resins as used in fibre reinforced plastics (FRP) process equipment were studied with regard to barrier properties, chemical resistance and long-term performance.

7. 5. Analysis of geometrically modified adhesive joints in steel beams strengthened with composite laminates

   Author : Reza Haghani Dogaheh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; Stress concentration; Fillet; Laminate; Reverse tapering; Normal tapering; Adhesive joint; FRP;

   Abstract : The use of bonded FRP laminates to strengthen and upgrade existing structures has attracted a great deal of attention during the past two decades. The attractiveness of this method is mainly due to the superior material properties of FRP laminates such as high strength and stiffness, as well as advantages associated with the bonding technique, such as ease of application and good fatigue performance.
