  1. 6. Modeling of the wet-out process in composites manufacturing

    Författare :Da Wu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process modeling; liquid composite molding; fiber preform deformation; free surface flow; porous media theory;

    Sammanfattning : The fiber reinforced polymer composites (FRPCs) are carving out a niche amid the keen market competition to replace the other material counterparts, e.g., metals. Due to the low weight and corrosion resistance, the FRPCs are wildly utilized from aviation to automobile industries; both in the sectors of civilian and defense. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly 3-hydroxybutyrate ; permeability; diffusion cells; poly lactide-co-glycolide acid ; mass-transport; polyethylene; poly lactic acid ; ethylene acrylic acid; interfaces; cellulose;

    Sammanfattning : Many of the products in our daily life consist of layered structures, where packaging materials and wound care products can be mentioned as examples. These structures often consist of different kind of polymeric materials and between these materials interfaces are formed. LÄS MER

  4. 8. Isolation, Characterization and Material Properties of Arabinoxylan from Barley

    Författare :Anders Höije; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical structure; moisture content; film formation; Arabinoxylan; isolation; mechanical properties; oxygen permeability;

    Sammanfattning : The growing amount of household waste and the limited supply of fossil fuel on earth make it important to find renewable resources for the production of biodegradable polymers for a variety of applications, particularly as packaging and other disposable products. Hemicelluloses are important components in all plants and the second most abundant plant biopolymers on earth. LÄS MER

  5. 9. Permeability of non-crimp fabrics : a computational fluid dynamics approach

    Författare :Markus Nordlund; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : In the present market for manufacturing of high performance structural parts for various applications such as aerospace, transportation, infrastructure, marine, sports and recreation, low weight, high performance composites are preferable. Non-Crimp Fabrics (NCFs) are often used for such applications due to its high mechanical properties and often cost effective production. LÄS MER
