  2. 1. Development of hierarchical cellulosic reinforcement for polymer composites

    Author : Abdelghani Hajlane; Angelika Bachinger; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : Cellulose is an environmentally friendly material which is obtainable in vast quantities, since it is present in every plant. Cellulosic fibers are commercially found in two forms: natural (flax, hemp, cotton, sisal, wood, etc.) and regenerated cellulose fibers (RCF). READ MORE

  4. 2. Hierarchical cellulosic reinforcement for composites: enhanced resistance to moisture and compatibility with polymers

    Author : Abdelghani Hajlane; Mikael Skrifvars; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : Cellulosic fibres (flax, hemp, regenerated cellulose) possess decent mechanical properties and they are gaining interest as an alternative to synthetic reinforcement (e.g. glass fibres) in polymers to reduce the petroleum consumption and pollution. READ MORE

  5. 3. Contactless Test of Circuit Boards

    Author : Abdelghani Renbi; Heli Jantunen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : Electronics are still continuing to respond to the small-feature size requirement for economical, performance and environmental benefits.Due to the non-idealities in the manufacturing process of circuit boards, electronics production yield is never 100 %. READ MORE

  6. 4. Improved PWB test methodologies

    Author : Abdelghani Renbi; Erik Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : Printed Wiring Board (PWB) and Printed Circuit Board Assembly (PCBA) testing aims to ensure an error free board after the etching and the assembly processes. After the etching process, several types of errors might occur such as opens and bridges, which are already, showstoppers in Direct Current (DC) applications. READ MORE
