  3. 3. Experimental methods to determine model parameters for failure modes of CFRP

    University dissertation from Institutionen för flygteknik

    Author : Daniel Svensson; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; delamination; energy release rate; compressive failure; cohesive modelling; composite;

    Abstract : The focus of this thesis is to develop methods to predict the damage response of CarbonFibre Reinforced Polymers (CFRP). In the pursuit of reducing the manufacturing costand weight of CFRP components, it is crucial to enable modelling of the non-linearresponse associated with various failure modes. READ MORE

  4. 4. Physical properties of dispersions and composites containing surface-grafted cellulose nanocrystals

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Lilian Forsgren; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite; Cellulose; Thermal stability; Cellulose nanocrystals; Tensile properties; Rheology;

    Abstract : The needs and requests from the society for non-fossil-based materials as well as more lightweight products are constantly increasing. The increasing awareness of the sustainability of the resources available paralleled by a growing population, point to a need for changes, if the population also aim for constantly higher standard of living.

    Abstract : Basic (apatite-based) calcium phosphate cements (CPCs), and acidic (brushite and monetite-based) CPCs are used as bone replacement materials because of their bioactivity, mouldability and ability to harden in place. However, their application is limited by their inherent brittleness and difficulties related to their handling. READ MORE
