  2. 1. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure

    Author : Daniel Svensson; Ulf Stigh; Bent Sørensen; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; Cohesive zone model; J-integral; LEFM; Delamination; Compressive failure; Technology; Teknik; Mechanics of Materials; Materialmekanik;

    Abstract : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.
