  1. 6. Thermo-Oxidative Degradation of High Temperature Polyimide Composites : Characterization and Modeling of Composites Affected by an Extreme Environment

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Magnus Persson; [2016]
    Nyckelord :Polyimide composite material; thermal and oxidative degradation; glass transition temperature; stiffness modeling;

    Sammanfattning : Carbon fiber (CF) 8-harness satin weave, T650/Neximid system of [(+45/-45)/(0/90)]2S and [(0/90)]4S layup was manufactured using resin transfer molding (RTM). The material was cut into 3-point bending specimens and treated for 24 hours in a burn oven at T=(320,350,375,400,450 & 500)°C. LÄS MER

    Sammanfattning : Ink-jet printing (IJP) using conductive inks, has gained the attention of scientistsand researchers during the past decades. Solar Cells (SCs), Radio FrequencyIdentication (RFID), E-papers and antennas are only some of the applicationsfor which IJP is being applied. IJP facilitates printing complex antenna structureswith a good resolution. LÄS MER
