1. Fatigue damage mechanisms in polymer matrix composites
Sammanfattning : Polymer matrix composites are finding increased use in structural applications, in particular for aerospace and automotive purposes. Mechanical fatigue is the most common type of failure of structures in service. The relative importance of fatigue has yet to be reflected in design where static conditions still prevail. LÄS MER
2. Nanostructured Cellulose Biocomposites : Effects from dispersion, network and interface
Sammanfattning : The major load bearing component in native wood, cellulose nanofibrils, are potential candidates for use as reinforcement in polymer matrices. This study is based on nanocellulose composites and attempts to prepare and characterize biocomposites with high nanocellulose content and investigate the influence of nanostructure on macroscopic properties.

3. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties
Sammanfattning : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. LÄS MER
4. Natural fiber composites : optimization of microstructure and processing parameters
Sammanfattning : Natural fiber composites, (NFC) are defined in this work as a group of materials where at least the fibers originates from renewable and CO2 neutral resources. NFC consists of a polymer matrix and a natural fiber. The fibers which originate from wood or plants can replace non-renewable fibers or fillers or simply replace part of the plastic. LÄS MER
5. Wood fiber composites : from processing and structure to mechanical performance
Sammanfattning : The work presented in this thesis has been focused on the mechanical properties of wood fiber composites. One goal has been to investigate the processing of wood polymer composite materials with good mechanical properties, and how to tailor these properties for different applications. LÄS MER
