2. 1. Wood fiber composites : processing, structure and properties

   Author : Lars-Olof Nordin; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : The goal of this work has been to investigate how to make wood polymer composite materials with good mechanical properties, which also could be tailored for different applications. The fundamental idea behind the work was that good mechanical properties of the composite material require that the stiffness and strength of the wood cell wall material are really utilized.

   Abstract : Through 270 million years of evolution, the finely tuned hierarchical structure of wood has been optimized for efficient nutrient transport and exceptional mechanical stability. Its distinctive orthotropic constitution can provide inspiration and design opportunities for the development of novel functional materials. READ MORE

6. 4. Wood-fibre composites : Stress transfer and hygroexpansion

   Author : Karin M. Almgren; Kristofer Gamstedt; Véronique Michaud; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : Wood fibres is a type of natural fibres suitable for composite applications. The abundance of wood in Swedish forests makes wood-fibre composites a new and interesting application for the Swedish pulp and paper industry. READ MORE

7. 5. High-Performance Composites from Modified Wood Fiber

   Author : Mats Westin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kraft lignin; fiberboard; lignocellulosic fiber; durability; wood fiber; mechanical properties; dimensional stability; decay resistance; acetylation; composite;

   Abstract : The objective of this work was to produce and evaluate high-performance wood fiber composites. High-performance was defined as: high dimensional stability and a high durability, including resistance to wood-decaying organisms (fungi, bacteria, and insects). READ MORE
