  1. 1. Environmental Impact Analysis of Flax Fibre Cultivation for Composite Reinforcement

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : Elin Jacobsson; [2018]
    Keywords : flax fibre; life cycle assessment; reinforcement; environmental impact assessment;

    Abstract : Searching for environmentally sustainable alternatives for reinforcement of composite materials, flax fibre has one of the most promising potentials due to its desired mechanical properties. The fact that flax is a bio-material, in contrast to conventional synthetic fibres, does not ensure a less environmental impact. READ MORE

  3. 2. Difference in marginal and internal fit between Luxatemp crowns and Empress crowns

    University essay from Umeå universitet/Institutionen för odontologi; Umeå universitet/Institutionen för odontologi

    Author : Aboud Habib; Sargon Shamoel; [2018]
    Keywords : ;

    Abstract : The purpose with this in-vitro study is to examine the difference in marginal and internal gap width between bis-acryl composite resins (Luxatemp Fluorescence) and IPS Empress crowns. A maxillary left first phantom Frasaco molar tooth placed in a maxillary Frasaco model was prepared for an all-ceramic crown. READ MORE

  4. 3. Numerical and experimental analysis of adhesively bonded T-joints : Using a bi-material interface and cohesive zone modelling

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap; Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Andreas Andersson Lassila; Marcus Folcke; [2018]
    Keywords : adhesive; cohesive zone modelling; Finite Element Method; mixed-mode; T-joint; fracture; experiment; cohesive laws; Bi-material Interface;

    Abstract : With increasing climate change the automotive industry is facing increasing demands regarding emissions and environmental impact. To lower emissions and environmental impact the automotive industry strives to increase the efficiency of vehicles by for example reducing the weight. READ MORE

  5. 4. Early assessment of composite structures : Framework to analyse the potential of fibre reinforced composites in a structure subjected to multiple load case

    University essay from KTH/Lättkonstruktioner; KTH/Hållfasthetslära (Avd.)

    Author : Srikanth Ananthasubramanian; Priyank Gupta; [2018]
    Keywords : MATLAB; Fibre Reinforced Plastics; finite-element; laminate design; classical laminate theory.;

    Abstract : To meet the need of lightweight chassis in the near future, a technological step of introducing anisotropic materials like Carbon Fibre Reinforced Plastics (CFRP) in structural parts of cars is a possible way ahead. Though there are commercially available tools to find suitability of Fibre Reinforced Plastics (FRPs) and their orientations, they depend on numerical optimization and complexity increases with the size of the model.

  6. 5. Failure Modeling of Curved Composite Beams : Numerical Modeling of Failure Onset and Propagation in L-Profile Beams

    University essay from KTH/Lättkonstruktioner

    Author : Suhas Gururaj Shetty; [2018]
    Keywords : ;

    Abstract : The high strength/stiffness-to-weight ratio that composite materials exhibit has led to the utilization of composites as alternative to traditional materials in weight-critical applications. However, the highly anisotropic nature of composites renders the strength prediction under complex loading challenging. READ MORE
