  1. 1. Failure prediction of orthotropic Non-Crimp Fabric reinforced composite materials

    Författare :Henrik Molker; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Orthotropic; Non crimp-fabric; Failure initiation; Design methodology; Carbon fibre composite;

    Sammanfattning : The automotive industry needs to reduce the energy consumption to decrease the impact on the environment. One part of this is to reduce the weight of cars, thereby reducing the fuel consumption. A promising way to be successful with this is to introduce carbon fibre composites in the structural parts.

  3. 2. Stiffness characterization in Non-Crimp Fabric Composites

    Författare :Hana Zrida; Spyros Tsampas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Lightweight materials with high stiffness and damage tolerance are requested for aerospace, marine and automotive industries. Many types of composite materials are today used in various types of load carrying structures, due to their excellent strength and stiffness to weight ratio. LÄS MER

  4. 3. Behaviour and material properties of composites for crash modelling

    Författare :Thomas Bru; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon fibre composite; non-crimp fabric; crushing; mechanical testing.;

    Sammanfattning : The transport industry must find solutions to reduce its impact on climate change. A promising way to reduce the weight of vehicles and therefore to reduce the CO2 emissions is to introduce components made of lightweight composite materials, in particular laminated carbon fibre reinforced polymers (CFRPs).

  5. 4. Industrial framework for hot-spot identification and verification in automotive composite structures

    Författare :Henrik Molker; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global - local; Failure initiation; Analysis framework; Carbon fibre composite; Non crimp-fabric; Orthotropic material; Sub-modelling;

    Sammanfattning : The automotive industry needs to reduce energy consumption to decrease environmental impact. This can be achieved by reducing the weight of cars, which would consequently reduce the energy consumption and emission of greenhouse gases. LÄS MER

  7. 5. Damage Tolerance of Impacted Composite Sandwich Structures

    Författare :Moeen ud din Saeed Rajput; Malin Åkermo; Stefan Hallström; Magnus Burman; Christian Berggreen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite sandwich; cellular; polymer; material characterization; modulus; non-crimp fabric; low velocity impact; vibration; uncertainty analysis; drop-weight impact; fractography; barely visible impact damage; X-ray microtomography; compression-after-impact; bending-after-impact; high speed image processing; damage resistance; damage tolerance; Aerospace Engineering; Flyg- och rymdteknik;

    Sammanfattning : This thesis deals with damage tolerance of impacted sandwich structures for load bearing applications. Composite sandwich structures find wide application as lightweight solutions in aerospace components, since weight reduction and less fuel emissions are primary concerns for aircraft manufactures.
