    Abstract : The rapid growth of plastic waste from food packaging around the world demands renewable substitutes, such as natural fibers and biocomposites. Wood fibers are natural fibers extracted from trees and are commonly used in packaging. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

  4. 3. The effect of different recovered fibres on mechanical properties of board

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Syed Ali Hassnain Shah; [2012]
    Keywords : Z-strength; mechanical properties; bending stiffness; couching method; recovered fibres; 4-ply board;

    Abstract : The objective of this work was to determine the influence of recovered fibres on the mechanical properties of board. Industrial board was provided by Fiskeby Board AB and laboratory board was made by using an isotropic sheet former. Board properties such as tensile strength, tensile stiffness, z-strength and bending stiffness were evaluated. READ MORE
