   Sammanfattning : This thesis treats various aspects of structural polymercomposites in aircraft applications. The mechanical performanceand quality of resin transfer molded (RTM) carbon fiberreinforced epoxy composites is studied. LÄS MER

3. 12. Forming of stacked unidirectional prepreg materials

   Författare :Ylva Larberg; Malin Åkermo; Dan Zenkert; Kevin Potter; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - Production; SRA - Produktion;

   Sammanfattning : To reduce cost of structural composites, the development of more efficient manufacturing methods is of great interest. An automatic tape layer (ATL) can be used to perform the layup in an efficient way for flat sheets and the second step is by pressure forming the prepreg stack onto a given mould. LÄS MER

7. 15. Hygrothermal Durability of Adhesively Bonded FRP/steel Joints

   Författare :Mohsen Heshmati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cohesive zone modelling; durability; moisture diffusion; Fibre reinforced polymer; adhesively bonded FRP steel joints; long-term performance;

   Sammanfattning : Fibre reinforced polymer (FRP) composites offer superior mechanical properties, such as specific strength and stiffness, corrosion resistance and light weight. Over the past four dec-ades, FRPs have been increasingly used for strengthening and repair of bridge structures, and more recently, in the manufacture of whole/hybrid FRP bridges. LÄS MER
