  1. 1. Variation Simulation Customized for Composites by Including FEM Simulations of Orthotropic Lamina

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Cornelia Jareteg; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometry assurance; FEM; Composites; Shell model; Process variation; Method of Influence Coefficients; Monte Carlo; Orthotropic material; Manufacturing; Tolerance analysis; Variation simulation; Spring-in;

    Abstract : The use of composite materials is increasing in many fields of production. Composite manufacturing, as well as other fields of production, suffers from uncertainties resulting in products that deviate from the specification. Geometry assurance is a common procedure used to keep the variations in product assemblies under control. READ MORE

  2. 2. Cellulose–Assisted Dispersion of Carbon Nanotubes : From Colloids to Composites

    University dissertation from KTH Royal Institute of Technology

    Author : Alireza Hajian; KTH.; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocelluloses; Carbon nanotubes; Composites; Colloids; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : It is a challenge to disperse nanoparticles to obtain a nanostructured composite. This thesis aims at providing a new route to fabricate carbon nanotube (CNT) composites and suggests mechanisms for nanocellulose–CNT interactions. This route is based on unmodified CNT dispersed in water with the help of nanocellulose. READ MORE

  3. 3. Resin composites Sandwich restorations and curing techniques

    University dissertation from Umeå : Odontologi

    Author : Anders Lindberg; Umeå universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Adaption; Clinical; Degree of conversion; Depth of cure; Flowable; Resin composite; Restorations; SEM; Medicin;

    Abstract : Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing demand for aesthetic restorations. READ MORE

  4. 4. Natural fiber composites optimization of microstructure and processing parameters

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Birgitha Nyström; Luleå tekniska universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : Natural fiber composites, (NFC) are defined in this work as a group of materials where at least the fibers originates from renewable and CO2 neutral resources. NFC consists of a polymer matrix and a natural fiber. The fibers which originate from wood or plants can replace non-renewable fibers or fillers or simply replace part of the plastic. READ MORE

  5. 5. Durability of Embedded Fibre Optic Sensors in Composites

    University dissertation from Institutionen för flygteknik

    Author : Klas Levin; KTH.; [2001]
    Keywords : composites; fibre optic sensor; embedded EFPI sensor; bragg grating sensor; durability. Fatique; impact strain measurement;

    Abstract : This thesis concerns various aspects of the durability offibre optic sensors embedded in composite. Since repair orreplacement of embedded sensors is not generally possible, thefunctional reliability of embedded sensors is one of the mostimportant prerequisites for successful use. READ MORE
