  4. 7. Stress-laminated-timber bridge decks subjected to ultimate loads

    Author : Kristoffer K J Ekholm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultimate-load tests; Stress-laminated timber; Timber bridges;

    Abstract : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. READ MORE

  5. 8. Deformability of unidirectional prepreg materials

    Author : Ylva Larberg; Malin Åkermo; Patrik Fernberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; prepreg; deformability; carbon composite; Vehicle engineering; Farkostteknik;

    Abstract :  To reduce cost of structural composites the development of more efficient manufacturing methods is of great interest. Sheet forming of thermoset prepreg, also known as hot drape forming, has been a promising manufacturing method for decades. An automatic tape layer (ATL) can be used to perform the lay-up in an efficient way. READ MORE

  6. 9. Modelling of Delamination Growth in Composite Structures

    Author : Niklas E. Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large deformation; interface; composite materials; 3D-shell; cohesive zone; regularization; shell element; delamination;

    Abstract : Delaminations constitute an important damage and failure mode in polymeric composite laminates. In order to explicitly incorporate and model the delamination progression within a finite element analysis, the meso-modelling concept is applied in the present work. The laminate is thereby represented by separate layers connected with interfaces. READ MORE

  7. 10. Aircraft composites and aeroelastic tailoring

    Author : Jakob Kuttenkeuler; KTH; []
    Keywords : polymer composites; testing; resin; transfer molding; RTM; process parameters; mechanical properties; aircraft; impact damage; BVID; modal; inverse method; uncertainties; aeroelasticity; optimization; wind tunnel; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE
