  1. 1. Experimental and numerical studies of intralaminar cracking in high performance composites

    Författare :Mohamed Sahbi Loukil; Janis Varna; Zoubir Ayadi; Constantinos Soutis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : The macroscopic failure of composite laminates subjected to tensile increasing load is preceded by initiation and evolution of several microdamage modes. The most common damage mode and the one examined in this thesis is intralaminar cracking in layers. LÄS MER

    Sammanfattning : Fiber reinforced polymer composite laminates make up more than 50% of modern aircrafts. Such composite laminates are exposed to various environmental and in-service thermo-mechanical load conditions. LÄS MER

  5. 4. Transverse cracking in cross-ply composites during static and fatigue loading at different temperatures

    Författare :Vivek Richards Pakkam Gabriel; Patrik Fernberg; Mohamed Sahbi Loukil; Kristofer Gamstedt; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer composite laminate; Static loading; Fatigue loading; Elevated temperature effect; Weibull distribution model; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : Polymer composite laminates are preferred in many load bearing applications for its tailorable mechanical properties while offering light-weight solution, corrosive resistance etc. Hence, polymer composites are attractive material choice for aircraft manufacturers to reduce weight and emissions.
