  1. 11. A spectroscopic study of polymer : Carbon nanotube composites

    Författare :Andreas Müller; Ove Andersson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Since the identification of carbon nanotubes (CNTs) by Ijima in 1991, this material has become a subject of great interest and effort in science because of the outstanding physical properties it exhibits. CNTs can be thought of as graphene sheets rolled into seamless cylinders of various diameters and in principle infinite length. LÄS MER

  3. 12. Durability of Embedded Fibre Optic Sensors in Composites

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : This thesis treats various aspects of structural polymercomposites in aircraft applications. The mechanical performanceand quality of resin transfer molded (RTM) carbon fiberreinforced epoxy composites is studied. LÄS MER

  5. 14. Poromechanical Modeling of Composites Manufacturing

    Författare :Mohammad Sadegh Rouhi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element Analysis FEA ; Polymer Composites; Manufacturing Technologies; Poromechanics;

    Sammanfattning : Fibre reinforced composite materials are used extensively in today's industry. On one hand, the low-weight feature of this kind of material gives important advantages such as lower fuel consumption and lower amount of CO2 emissions. LÄS MER

  7. 15. Development of Constituents for Multi-functional Composites Reinforced with Cellulosic Fibers

    Författare :Zainab Al-Maqdasi; Roberts Joffe; Nazanin Emami; Liva Pupure; Yvonne Aitomäki; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose fibers; multi-functional; composites; nano-reinforcement; thermoplastics; development; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : Bio-basedcomposites are being increasingly used in applications where weight saving,and environmental friendliness is as important as structural performance. Obviously, bio-based materials have their limitations regarding durability and stability of the properties,but their potential in use for advanced applications can be expanded if they were functionalized and considered beyond their structural performance.
