2. 1. Inelastic analysis of fiber reinforced polymeric composites

   Author : Modris Megnis; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : Fiber reinforced polymer composites are seeing increased use in the outomotive industry and other applications. This is because of the potential for rational and economical production in large series of complex shaped parts. Properties such as high strength to weight ratio and superior impact properties are of particular interest. READ MORE

4. 2. 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

5. 3. Mechanics of composites with fiber bundle meso-structure

   Author : Normunds Jekabsons; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : The presented thesis analyze mechanical phenomena in fibrous composites with fiber bundle sub-structure (woven composite sheet molding compounds (SMC) etc.). This sub-structure defines an intermediate meso-scale between the scale of individual fibers and macro-scale of the composite. READ MORE

6. 4. Analysis of transverse composite cross-ply laminates

   Author : Janis Varna; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : Advanced polymer composites are commonly based on thin prepreg plies stacked at different angles to form a laminate. When the laminate is loaded, intralaminar transverse cracking in off-axis plies is one of the first damage modes. In the presented thesis, cross-ply laminates are used to study the transverse cracking phenomenon. READ MORE

7. 5. Hygroelastic behaviour of wood-fibre based materials on the composite, fibre and ultrastructural level

   Author : Razvan Cristian Neagu; Kristofer Gamstedt; Staffan Toll; KTH; []
   Keywords : wood fibres; ultrastructure; structure-property relations; microfibril angle; composites; characterization methods; hygroelastic properties; micromechanics; modelling; reinforcement potential; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Wood fibres can be used as reinforcement in plastics for load carrying purposes. Some advantages compared with conventional man-made fibres are that wood fibres come from a renewable resource, have high specific stiffness and strength, are generally less hazardous to health, biodegradable, and can be manufactured at low cost and high volumes.
