  3. 2. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

    Författare :Mikael Danielsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

    Sammanfattning : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. LÄS MER

  4. 3. In-plane Compressive Response of Sandwich Panels

    Författare :Anders Lindström; Dan Zenkert; Stefan Hallström; Leif Carlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sandwich; Finite Element Analysis FEA ; Fracture; In-plane compression; Other engineering mechanics; Övrig teknisk mekanik; Structural and vibration physics; Struktur- och vibrationsfysik;

    Sammanfattning : The high specific bending stiffness of sandwich structures can with advantage be used in vehicles to reduce their weight and thereby potentially also their fuel consumption. However, the structure must not only meet the in-service requirements but also provide sufficient protection of the vehicle passengers in a crash situation. LÄS MER

  7. 5. Damage tolerance and residual strength of composite sandwich structures

    Författare :Peter H. Bull; KTH; []
    Nyckelord :sandwich structure; damage tolerance; carbon fiber; compression after impact;

    Sammanfattning : The exploitation of sandwich structures as a means toachieve high specific strength and stiffness is relatively new.Therefore, the knowledge of its damage tolerance is limitedcompared to other structural concepts such as truss bars andmonocoque plate solutions. Several aspects of the damage tolerance of sandwichstructures are investigated. LÄS MER
